Thursday, February 20, 2025

Without an air purifier for pets, our furry friends’ dander can get the better of us. As much as we love our animals, they are ripe with allergens, which can cause serious issues for those with sensitivities. But living with a cat or dog doesn’t have to result in misery for those with allergies, even in our own homes. We’ve chosen the Levoit Core P350 as the best overall air purifier for pets due to its mix of features for its price. The best air purifiers for pets offer multiple levels of filtration to capture everything from dander and other pet allergens to clumps of loose fur and even odors, getting rid of that wet dog smell.  Best overall: Levoit Core P350 Best splurge: Molekule Air Pro Best for large rooms: GermGuardian Air Purifier Best for small rooms: Molekule Air Mini+ Best budget: Winix A231 Tower H13 How we chose the best air purifiers for pets My household comprises a dog whose favorite thing is rolling in the grass, a cat, and a husband who is allergic to all three things. As a result, air purifiers are a must in our household to combat the constant barrage of allergens. When selecting the best air purifiers for pets, we prioritized devices with high-efficiency particulate air (HEPA) filters, as these offer the best results for reducing allergens. We then looked at other filtration methods (some offer multiple varieties in a single air purifier), room size coverage, and odor-reducing features. Finally, we factored in device size, noise levels, and any additional features, such as timers and connectivity options. We based our selections on hands-on experience, customer feedback, and editorial reviews.  The best air purifiers for pets: Reviews & Recommendations Having pets in your home doesn’t mean you must be miserable and simply deal with allergies, thanks to air purifiers. Purifiers for pets can provide significant relief from the effects of dander and other allergens, like what gets tracked in the house after a long walk, and even get rid of those less-than-pleasant pet odors and floating fluff.  Best overall: Levoit Core P350 Pros Quiet Compact Plenty of settings and controls Pet Lock keeps settings from changing if it gets bumped Cons No app connectivity Specs Filter type(s): Fabric pre-filter, True HEPA filter, and activated carbon filter Maximum coverage area: Up to 218 square feet Dimensions: 8.7 x 8.7 x 14.2 inches Weight: 7.5 pounds The Levoit Core P350 earns our top slot thanks to its balance of features, design, quality, and price. Levoit purpose-built this air purifier for pets, as is evidenced by the Pet-Lock function to keep your furry friend from accidentally changing settings on the touchscreen display. It’s also a bonus in households with kids.  The Core P350 features a three-in-one filtration system. The Non-Woven Fabric Pre-Filter traps pet fur to reduce the amount of hair on your floors. The Efficient Activated Carbon Filter neutralizes pet odors to keep your home smelling fresh. It effectively removed the dog smell from my office, where the dog crate lives. And finally, the True HEPA filter cleans the air to remove allergens.  All three filter types are packed in a relatively compact package with a sleek, attractive design that will fit well in just about any space. It’s powerful enough to purify a 219-square-foot room in only 12 minutes, yet can produce as little as 24 decibels. Three fan modes allow you to fine-tune noise levels and cleaning effectiveness, and a night mode turns off lights so you can sleep without distractions.  The primary downside to the Core P350 is that it doesn’t pair with an app and doesn’t offer an air quality sensor. But at $130, it’s hard to beat all that this air purifier for pets has to offer.  Best splurge: Molekule Air Pro Pros Very quiet Automatic mode detects changes in air quality Six manual speeds offer lots of control Attractive design Tackles odors, smoke particles, dust, and more Cons Expensive Specs Filter type(s): PECO, True- HEPA, and carbon filters Maximum coverage area: Up to 1000 square feet Dimensions: 23.1 x 10.9 inches Weight: 22.9 pounds If thorough air-cleaning abilities, smart design, and broad coverage are of utmost importance, the Molekule Air Pro is your best bet. This larger air purifier for pets covers up to 1,000 square feet in rooms with ceilings up to eight feet. The modern design will look smart in your home, and the vegan leather handle makes it easier to move when cleaning a different room. The Air Pro features a True HEPA filter to capture 99.7 percent of small particles. A carbon filter removes odors and gases. But what makes it unique is the light-activated PECO technology, which destroys organic pollutants instead of simply trapping them. In 2023, scientists at the Florida International University published a preclinical study in Nature examining how PECO filters reduce allergic reactions to cat dander. The team found that the PECO filter was more effective at destroying cat dander, thus reducing allergy responses. The air in the room where I have my Air Pro definitely smells fresher since getting this purifier up and running.  On top of effective air purifying abilities, Molekule’s Air Pro is also extremely smart. Thanks to the built-in air quality sensor, it offers two automatic modes. One automatically adjusts the fan speed when it detects increased particles and chemical levels. When I burned some food while cooking, the fan spun up to clear out the smoke faster. The other automatic mode does the same, but silently. There are also six manual fan speeds, so you can take full control when you want. It operates at noise levels between 30-65 decibels, with the lowest level barely noticeable over normal white noise in your home.  The Molekule app is easy to navigate and provides daily and weekly air quality assessments. With the Air Pro, you can even break these down into specific pollutants, such as carbon dioxide, VOCs, and various particle sizes. It will remind you when to change filters, and you can subscribe to receive new filters automatically. The Air Pro is expensive, to be sure. But it is ripe with features, scientifically backed, and attractively designed. The steep price tag is the only reason this didn’t earn our best overall designation. Best for large rooms: GermGuardian Air Purifier Pros Cleans up to 1,760 square feet Three fan speed settings UV-C light reduces germs, viruses, and bacteria Removes odors Cons Two fan speeds are quite loud A bit bulky Specs Filter type(s): True HEPA, UV-C light, carbon pre-filter Maximum coverage area: Up to 1760 square feet Dimensions: 9.65 x 15.95 x 20.87 inches Weight: 13 pounds Large spaces require more robust air purifiers for pets. The GermGuardian can purify rooms up to 1,760 square feet, fitting the bill. In rooms that size, it can circulate the air one time per hour. Or, for faster cleaning, it can cycle the air 4.8 times per hour in 365-square-foot spaces. It features three levels of cleaning, including a True HEPA filter, a carbon pre-filter to remove odors and trap pet hair, and a UV-C light to reduce airborne germs.  The GermGuardian is roughly the size of a dehumidifier, though slightly more narrow. It will require some space, but since it’s made for large rooms, that shouldn’t be too much of an issue for most. It’s relatively affordable for the large coverage as well, which is nice to see. A night mode turns off the device’s lights. And an eight-hour auto-off timer keeps it from running unnecessarily.  Our main complaint with the GermGuardian is the fan speed settings. There is not much difference in noise between two levels, and both are quite loud. The third setting is barely noticeable, so we primarily keep it at this setting. Having more even differences between the three levels for more control would be nice. There are no sensor or automatic controls, so you must manually change fan speeds. But, overall, it seemed to cut back on our allergies when running and effectively removed odors as well, which is appreciated.  Best for small rooms: Molekule Air Mini+ Pros Extremely quiet Pairs with the Molekule app  FDA-cleared as a medical device Compact and portable Cons Pricey for the size Specs Filter type(s): PECO, True- HEPA, and carbon filters Maximum coverage area: Up to 250 square feet Dimensions: 8.26 x 8.26 x 12 inches Weight: 7.3 pounds The Molekule Air Mini+ is essentially a smaller version of the Air Pro mentioned above. It features the same proprietary PECO-HEPA Tri-Power to purify air from various allergens and pollutants effectively. Like the Air Pro, the Air Mini+ is DA-cleared as a 510(k) Class II medical device to destroy viruses, bacteria, and mold.  The Air Mini features a particle sensor to detect and track PM2.5 levels over time, which you can view in the app. The automatic mode spins up the fan as needed, adapting to the current conditions in your room. Or you can manually adjust with five different speed settings, resulting in noise levels from 39 to 62 decibels.  This compact air purifier for pets can purify up to 250 square feet. We’ve had ours in our bedroom and have noticed much-improved allergies while trying to sleep. The vegan leather handle makes it easy to move if you need to bring it from room to room with you. Although the PECO filter is light-activated, it is very dim and doesn’t cause much of a glow in a dark room at night. There are controls on the top of the device that are easy to use, or you can change settings via the Molekule app as well. Overall, it’s a sleek, effective little air purifier. Best budget: Winix A231 Tower H13 Pros Washable pre-filter saves money Carbon filter reduces odors Automatic mode with built-in sensor and air quality indicator Offers a dedicated sleep mode Cons Fairly loud, even on lower settings Specs Filter type(s): Washable fine mesh pre-filter, activated carbon filter, True HEPA filter Maximum coverage area: Up to 230 square feet Dimensions: 9.5 x 9.5 x 14.6 inches Weight: The Winix A231 offers quality air purification even for those on a tight budget. And despite the friendly price, it still has plenty of features, making it our best value pick. Most notable for an air purifier for pets at this price is the built-in sensor and automatic mode. Plus, the air quality indicator will alert you to changes in air quality with different light colors on the top of the device.   This Winix air filter features three levels of purification. The True HEPA filter captures 99.97 percent of airborne particles as small as 0.3 microns in size. The carbon filter reduces odor-causing VOCs to keep your room smelling fresh. A washable fine mesh pre-filter traps larger airborne particles, including pet hair. We love to see a washable design since it saves you money and reduces the environmental impact.  Unique to this air purifier is the Winnix PlasmaWave Air Cleaning Technology, which can be turned on or off. Winix says this acts as a permanent filter to break down odor, allergens, chemical vapors, and other pollutants. Unfortunately, users have reported that it is loud even on the lowest fan speed, though the sleep mode does provide quiet operation. But for the price, you’ll be hard-pressed to find as many features or quality in other options. Things to consider when shopping for the best air purifiers for pets Air purifiers for pets can vary from extremely simple devices with just a few settings to tech-heavy options with all sorts of fancy features. No matter what variety you are looking for, there are some key things to look out for to ensure you get a quality purifier that will actually clean your air.  Filter types The most important aspect of any air purifier is the thing doing the purifying—the filters. High-efficiency particulate air (HEPA) filters are the best available, so prioritize air purifiers with this type of filter for best results. That’s because HEPA filters can remove 99.97 percent of dust, pollen, mold, bacteria, or any other airborne particles as small as 0.3 microns, according to the EPA.  However, you’ll want to pay close attention to HEPA filter mentions on air purifier listings. There are True HEPA filters, which are highly effective. But there are also HEPA-like filters, which are not certified to meet the standards mentioned by the EPA.  Many air purifiers rely on multiple types of filters, so there are other filter types to pay attention to—some feature activated carbon filters, which work to reduce odors. For households with pets, this may be an extremely important feature. If you have extra furry friends that make it impossible to keep up with vacuuming, look for devices with a pre-filter, which will catch loose hair to prevent it from blocking up the HEPA filter. Some air filters also feature a UV light to kill airborne bacteria.  Room size As with any air filter, manufacturers build pet air purifiers for specific room sizes. This will be listed in square footage. A small purifier meant for a 350-square-foot room won’t work well in a vast, open space. On the other hand, a large air purifier meant for over 1,000 square feet will be overkill for a tiny bedroom. Be sure to consider where you will put the filter and roughly how many square feet it is before selecting. Clean Air Delivery Rate (CADR) Clean Air Delivery Rate (CADR) refers to the volume of filtered air an air purifier delivers. The CADR is broken into separate scores for tobacco smoke, pollen, and dust. The CADR of your air purifier should be equivalent to at least two-thirds of the room’s area, according to the Association of Home Appliance Manufacturers (AHAM). For example, for a 120-square-foot room, it “would be best to have an air cleaner with a smoke CADR of at least 80.”  Using an air purifier with a CADR number larger than two-thirds of the room’s square footage simply means that it will clean the air more often and faster, which isn’t bad. Unfortunately, not all manufacturers will list CADR numbers. But it is worth checking to see if they are provided.   Replacement filter cost To keep your filter working, you’ll need to replace filters occasionally. Some are reusable, though they will still require proper cleaning. If you are on a budget, be sure to factor in the cost of replacement filters on top of the initial cost of the air purifier for pets. Some companies, such as Molekule, offer subscription services to send you new filters when it’s time automatically. If you tend to forget such things, you may want to opt for a device with a subscription service to keep your air clean.  Noise levels Air filters use a fan to pull air through a filter, inevitably producing noise. Some are louder than others, though. Manufacturers will occasionally list decibel levels; if noise is a concern for your household, check to see if the decibel level is provided on the models you are considering.  Luckily, many devices provide multiple fan levels. That means you can turn it up when you want a boost of cleaning and then lower the fan noise when you are trying to watch TV. You can even find models with specific sleep modes to keep the volume down when it’s time for bed. Additional features Beyond the necessities, you may find additional features on air purifiers for pets that could be of interest. Some offer timers so that you aren’t constantly running the unit. Others feature air quality sensors to keep you aware of the air quality in a given room. Others provide app connectivity with reminders to change filters, remote control features, and more.  FAQs Q: Do air purifiers really work for pets? Yes, air purifiers are effective at removing pet-related allergens. A 2022 study found that “air filtration was effective in removing mites, cat and dog allergens and also particulate matter from ambient indoor air, offering a fast and simple solution to mitigate allergen exposome. Q: Do air purifiers remove pet smells? Certain air purifiers remove pet smells, but not all. Pet odors are the result of volatile organic compounds (VOCs). The molecules in VOCs are too small for HEPA filters, so an air purifier with only that variety of filtration will not remove the odors. However, an air purifier with a carbon filter will trap odors to remove them from the air. If pet odors are a significant concern, a purifier with a carbon filter will be crucial. Keep in mind, though, that carbon filters need to be changed fairly frequently to maintain effectiveness. That cost can add up quickly.For an alternative to carbon filters, you may want to consider Molekule’s proprietary PECO technology. Intertek, a Nationally Recognized Testing Laboratory (NRTL), independently tested the PECO technology and found it to be effective against airborne chemicals. Q: Where do you put an air purifier for pets? There are a few things to consider when choosing a location for your air purifier. First, placing the purifier close to the pollutant source will make it more effective. For example, putting the air filter by a litter box, dog crate, or wherever your pet spends time will clean up the air before it has time to travel around your house.Second, you may want to place your air purifier where you spend most of your time so that you actually benefit from the clean air. If you suffer from bad allergies at night, a small air purifier for your nightstand may offer the most impact. Finally, air purifiers need airflow to do their job. Placing it against a wall can limit that and may even damage the device. Be sure to provide a little breathing room for the air purifier to function properly. Q: How do you maintain an air purifier? Each air filter will have different maintenance requirements. Some rely on reusable filters that need to be vacuumed or washed out. Others use disposable filters that need to be replaced every few months. The best air purifiers for pets will offer a light or app notification that alerts you when it’s time to change the filter, but consult your product manual to keep the device working as it should.

Things to consider when shopping for the best air purifiers for pets

Air purifiers for pets can vary from extremely simple devices with just a few settings to tech-heavy options with all sorts of fancy features. No matter what variety you are looking for, there are some key things to look out for to ensure you get a quality purifier that will actually clean your air. 

Filter types

The most important aspect of any air purifier is the thing doing the purifying—the filters.

Room size

As with any air filter, manufacturers build pet air purifiers for specific room sizes. This will be listed in square footage. A small purifier meant for a 350-square-foot room won’t work well in a vast, open space. On the other hand, a large air purifier meant for over 1,000 square feet will be overkill for a tiny bedroom. Be sure to consider where you will put the filter and roughly how many square feet it is before selecting.

Clean Air Delivery Rate (CADR)

Clean Air Delivery Rate (CADR) refers to the volume of filtered air an air purifier delivers. The CADR is broken into separate scores for tobacco smoke, pollen, and dust. The CADR of your air purifier should be equivalent to at least two-thirds of the room’s area, according to the Association of Home Appliance Manufacturers (AHAM). For example, for a 120-square-foot room, it “would be best to have an air cleaner with a smoke CADR of at least 80.” 

Using an air purifier with a CADR number larger than two-thirds of the room’s square footage simply means that it will clean the air more often and faster, which isn’t bad. Unfortunately, not all manufacturers will list CADR numbers. But it is worth checking to see if they are provided.

Air filters use a fan to pull air through a filter, inevitably producing noise. Some are louder than others, though. Manufacturers will occasionally list decibel levels; if noise is a concern for your household, check to see if the decibel level is provided on the models you are considering. 

Luckily, many devices provide multiple fan levels. That means you can turn it up when you want a boost of cleaning and then lower the fan noise when you are trying to watch TV. You can even find models with specific sleep modes to keep the volume down when it’s time for bed.

Additional features

Beyond the necessities, you may find additional features on air purifiers for pets that could be of interest. Some offer timers so that you aren’t constantly running the unit. Others feature air quality sensors to keep you aware of the air quality in a given room. Others provide app connectivity with reminders to change filters, remote control features, and more. 

FAQs

Q: Do air purifiers really work for pets?

Yes, air purifiers are effective at removing pet-related allergens. A 2022 study found that “air filtration was effective in removing mites, cat and dog allergens and also particulate matter from ambient indoor air, offering a fast and simple solution to mitigate allergen exposome.

Q: Do air purifiers remove pet smells?

Certain air purifiers remove pet smells, but not all. Pet odors are the result of volatile organic compounds (VOCs). The molecules in VOCs are too small for HEPA filters, so an air purifier with only that variety of filtration will not remove the odors. However, an air purifier with a carbon filter will trap odors to remove them from the air. If pet odors are a significant concern, a purifier with a carbon filter will be crucial. Keep in mind, though, that carbon filters need to be changed fairly frequently to maintain effectiveness. That cost can add up quickly.

For an alternative to carbon filters, you may want to consider Molekule’s proprietary PECO technology. Intertek, a Nationally Recognized Testing Laboratory (NRTL), independently tested the PECO technology and found it to be effective against airborne chemicals.

Q: Where do you put an air purifier for pets?

There are a few things to consider when choosing a location for your air purifier. First, placing the purifier close to the pollutant source will make it more effective. For example, putting the air filter by a litter box, dog crate, or wherever your pet spends time will clean up the air before it has time to travel around your house.

Second, you may want to place your air purifier where you spend most of your time so that you actually benefit from the clean air. If you suffer from bad allergies at night, a small air purifier for your nightstand may offer the most impact. Finally, air purifiers need airflow to do their job. Placing it against a wall can limit that and may even damage the device. Be sure to provide a little breathing room for the air purifier to function properly.

Q: How do you maintain an air purifier?

Each air filter will have different maintenance requirements. Some rely on reusable filters that need to be vacuumed or washed out. Others use disposable filters that need to be replaced every few months. The best air purifiers for pets will offer a light or app notification that alerts you when it’s time to change the filter, but consult your product manual to keep the device working as it should.

Final thoughts on the best air purifiers for pets

As much as we love the animals in our lives, they put out an awful lot of allergens. Even those without serious allergies may suffer from minor reactions to all that dander and associated pollutants. The best air purifier for pets will keep the air clean even with a small zoo in your house, making it more comfortable and safer for everyone involved.

A “scientific sandbox” lets researchers explore the evolution of vision systems

The AI-powered tool could inform the design of better sensors and cameras for robots or autonomous vehicles.

Why did humans evolve the eyes we have today?While scientists can’t go back in time to study the environmental pressures that shaped the evolution of the diverse vision systems that exist in nature, a new computational framework developed by MIT researchers allows them to explore this evolution in artificial intelligence agents.The framework they developed, in which embodied AI agents evolve eyes and learn to see over many generations, is like a “scientific sandbox” that allows researchers to recreate different evolutionary trees. The user does this by changing the structure of the world and the tasks AI agents complete, such as finding food or telling objects apart.This allows them to study why one animal may have evolved simple, light-sensitive patches as eyes, while another has complex, camera-type eyes.The researchers’ experiments with this framework showcase how tasks drove eye evolution in the agents. For instance, they found that navigation tasks often led to the evolution of compound eyes with many individual units, like the eyes of insects and crustaceans.On the other hand, if agents focused on object discrimination, they were more likely to evolve camera-type eyes with irises and retinas.This framework could enable scientists to probe “what-if” questions about vision systems that are difficult to study experimentally. It could also guide the design of novel sensors and cameras for robots, drones, and wearable devices that balance performance with real-world constraints like energy efficiency and manufacturability.“While we can never go back and figure out every detail of how evolution took place, in this work we’ve created an environment where we can, in a sense, recreate evolution and probe the environment in all these different ways. This method of doing science opens to the door to a lot of possibilities,” says Kushagra Tiwary, a graduate student at the MIT Media Lab and co-lead author of a paper on this research.He is joined on the paper by co-lead author and fellow graduate student Aaron Young; graduate student Tzofi Klinghoffer; former postdoc Akshat Dave, who is now an assistant professor at Stony Brook University; Tomaso Poggio, the Eugene McDermott Professor in the Department of Brain and Cognitive Sciences, an investigator in the McGovern Institute, and co-director of the Center for Brains, Minds, and Machines; co-senior authors Brian Cheung, a postdoc in the  Center for Brains, Minds, and Machines and an incoming assistant professor at the University of California San Francisco; and Ramesh Raskar, associate professor of media arts and sciences and leader of the Camera Culture Group at MIT; as well as others at Rice University and Lund University. The research appears today in Science Advances.Building a scientific sandboxThe paper began as a conversation among the researchers about discovering new vision systems that could be useful in different fields, like robotics. To test their “what-if” questions, the researchers decided to use AI to explore the many evolutionary possibilities.“What-if questions inspired me when I was growing up to study science. With AI, we have a unique opportunity to create these embodied agents that allow us to ask the kinds of questions that would usually be impossible to answer,” Tiwary says.To build this evolutionary sandbox, the researchers took all the elements of a camera, like the sensors, lenses, apertures, and processors, and converted them into parameters that an embodied AI agent could learn.They used those building blocks as the starting point for an algorithmic learning mechanism an agent would use as it evolved eyes over time.“We couldn’t simulate the entire universe atom-by-atom. It was challenging to determine which ingredients we needed, which ingredients we didn’t need, and how to allocate resources over those different elements,” Cheung says.In their framework, this evolutionary algorithm can choose which elements to evolve based on the constraints of the environment and the task of the agent.Each environment has a single task, such as navigation, food identification, or prey tracking, designed to mimic real visual tasks animals must overcome to survive. The agents start with a single photoreceptor that looks out at the world and an associated neural network model that processes visual information.Then, over each agent’s lifetime, it is trained using reinforcement learning, a trial-and-error technique where the agent is rewarded for accomplishing the goal of its task. The environment also incorporates constraints, like a certain number of pixels for an agent’s visual sensors.“These constraints drive the design process, the same way we have physical constraints in our world, like the physics of light, that have driven the design of our own eyes,” Tiwary says.Over many generations, agents evolve different elements of vision systems that maximize rewards.Their framework uses a genetic encoding mechanism to computationally mimic evolution, where individual genes mutate to control an agent’s development.For instance, morphological genes capture how the agent views the environment and control eye placement; optical genes determine how the eye interacts with light and dictate the number of photoreceptors; and neural genes control the learning capacity of the agents.Testing hypothesesWhen the researchers set up experiments in this framework, they found that tasks had a major influence on the vision systems the agents evolved.For instance, agents that were focused on navigation tasks developed eyes designed to maximize spatial awareness through low-resolution sensing, while agents tasked with detecting objects developed eyes focused more on frontal acuity, rather than peripheral vision.Another experiment indicated that a bigger brain isn’t always better when it comes to processing visual information. Only so much visual information can go into the system at a time, based on physical constraints like the number of photoreceptors in the eyes.“At some point a bigger brain doesn’t help the agents at all, and in nature that would be a waste of resources,” Cheung says.In the future, the researchers want to use this simulator to explore the best vision systems for specific applications, which could help scientists develop task-specific sensors and cameras. They also want to integrate LLMs into their framework to make it easier for users to ask “what-if” questions and study additional possibilities.“There’s a real benefit that comes from asking questions in a more imaginative way. I hope this inspires others to create larger frameworks, where instead of focusing on narrow questions that cover a specific area, they are looking to answer questions with a much wider scope,” Cheung says.This work was supported, in part, by the Center for Brains, Minds, and Machines and the Defense Advanced Research Projects Agency (DARPA) Mathematics for the Discovery of Algorithms and Architectures (DIAL) program.

Common household rat poisons found to pose unacceptable risk to wildlife as animal advocates push for ban

Environmentalists say proposed temporary suspension of second-generation anticoagulant rodenticides ‘doesn’t go far enough’Follow our Australia news live blog for latest updatesGet our breaking news email, free app or daily news podcastCommonly available rat poisons pose unacceptable risks to native wildlife, according to a government review that has stopped short of recommending a blanket ban on the products, to the consternation of animal advocates.The long-awaited review of first- and second-generation anticoagulant rodenticides – FGARs and SGARs – has recommended the cancellation of some products, but a large array of waxes, pellets and blocks could continue to be sold to consumers subject to stricter labelling and conditions of use.

Commonly available rat poisons pose unacceptable risks to native wildlife, according to a government review that has stopped short of recommending a blanket ban on the products, to the consternation of animal advocates.The long-awaited review of first- and second-generation anticoagulant rodenticides – FGARs and SGARs – has recommended the cancellation of some products, but a large array of waxes, pellets and blocks could continue to be sold to consumers subject to stricter labelling and conditions of use.Baits containing anticoagulant rodenticides are widely available in supermarkets and garden stores such as Bunnings, Coles and Woolworths.The baits have come under scrutiny because they have been found in dead native animals such as tawny frogmouths, powerful owls and quolls that had eaten poisoned rats and mice.The second-generation products are more toxic and are banned from public sale in the United States and parts of Canada and highly restricted in the European Union.Commercially available rat poisons have been found in dead native animals. Photograph: Fabio De Paola/The GuardianConsumers can identify SGARs in Australia by checking whether they contain one of the following active ingredients: brodifacoum, bromadiolone, difethialone, difenacoum and flocoumafen. There are three FGAR active ingredients registered for use in Australia: warfarin, coumatetralyl and diphacinone.The Australian Pesticides and Veterinary Medicines Authority (APVMA), in response to the review which was published Tuesday, has proposed a temporary suspension of SGARs while public consultation about the recommendations is under way. If the suspension goes ahead the APVMA said the affected products could still be used, but only in accordance with the proposed stricter conditions.“If suspended, the importation or manufacture of SGARs would be illegal. They could only be sold if they meet the new strict conditions around pack size and use,” a spokesperson said.Holly Parsons, of BirdLife Australia, said the review “doesn’t go far enough and crucially, fails to address secondary poisoning that is killing owls and birds of prey” such as when, for example, a native bird ate a poisoned rat.“Despite overwhelming evidence provided in support of the complete removal of SGARs from public sale, we’re yet to see proposed restrictions that come close to achieving this,” Parsons said.She said consumers should be able to “walk into stores under the assumption that the products available to them aren’t going to inadvertently kill native animals” but the APVMA has put “the responsibility on to the consumer with an expectation that labels are fully read and followed – and we know that won’t be the case”.The review also recommended cancelling the registration of anticoagulant rodenticides baits that come in powder and liquid form or which do not contain dyes or bittering agents, finding they do not meet safety criteria.But it found other baits sold as waxes, pellets and blocks could continue to be sold to consumers with some changes to labelling and conditions of use.Sign up: AU Breaking News emailThe APVMA found that under “current instructions” it could not be satisfied that these types of products would not have unintended, harmful effects on non-target animals, including native wildlife, nor that they would not pose undue safety risks to people who handled them including vulnerable people such as children.But it found the conditions of product registration and other “relevant particulars” could be varied in such a way as to allow the authority “to be satisfied that products will meet the safety criteria”.Some of the proposed new instructions would include limiting mice baits to indoor use only when in tamper-resistant bait stations; placing outdoor rat baits in tamper-proof stations within two metres of outside a building; changes to pack sizes; and tighter directions for the clean-up and disposal of carcasses and uneaten baits.The recommendations are subject to three months of public consultation before the authority makes a final decision.John White is an associate professor of wildlife and conservation biology at Deakin University. In 2023 he worked with a team of researchers that studied rat poison in dead tawny frogmouths and owls, who found 95% of frogmouths had rodenticides in their livers and 68% of frogmouths tested had liver rodenticide levels consistent with causing death or significant toxicological impacts.He said the authority’s proposed changes failed to properly tackle the problem that SGARS, from an environmental perspective, were “just too toxic”.White said even if the authority tightened the conditions of use and labelling rules there was no guarantee that consumers would follow new instructions. “We should be completely banning these things, not tinkering at the edges,” he said.A spokesperson for Woolworths said the supermarket would await the APVMA’s final recommendations “to inform a responsible approach to these products, together with the suppliers of them”.They said the chain stocked “a small range of second-generation anticoagulant rodenticides for customers who might have a problem with rats or mice in their home, workplace, and especially in rural areas where it’s important for customers to have access to these products” while also selling “a number of alternative options”.Bunnings and Coles declined to comment.

Trail Cameras in Vermont Captured Something Strange: Moths Sipping a Moose's Tears

Tear-drinking, known as lachryphagy, has mostly been observed in the tropics, so scientists were somewhat surprised to find the unusual behavior so far north

Trail Cameras in Vermont Captured Something Strange: Moths Sipping a Moose’s Tears Tear-drinking, known as lachryphagy, has mostly been observed in the tropics, so scientists were somewhat surprised to find the unusual behavior so far north Sarah Kuta - Daily Correspondent December 16, 2025 8:49 a.m. A trail camera in Vermont captured 80 photos of moths fluttering around a moose's head, likely slurping up its tears. Vermont Fish and Wildlife Department Laurence Clarfeld was sifting through images captured by a trail camera in Vermont when he came across a photo that stopped him in his tracks. Clarfeld, an environmental scientist at the University of Vermont, knew he was looking at a moose. But, beyond that, he was totally perplexed. “It almost looked like the moose had two [additional] eyes,” he tells Scientific American’s Gennaro Tomma. When he flipped through more photos in the sequence, Clarfeld finally understood what he was seeing: Moths were sipping tears straight from the ungulate’s eyes. Scientists have observed this unusual phenomenon, known as lachryphagy, among other types of animals. But, as far as anyone knows, the photos represent the first documented evidence of moths drinking moose tears. Clarfeld and his colleagues describe the encounter in a new paper published November 20 in the journal Ecosphere.  Moths seen drinking moose tears for first time ever The photos were captured in the early morning hours of June 19, 2024, in the Green Mountain National Forest, a large swath of protected woodlands in southern Vermont. Researchers had deployed them as part of an ongoing wildlife survey by the Vermont Fish and Wildlife Department. In total, the camera captured 80 snapshots of the moths fluttering around a moose’s head. The photos don’t specifically show the moths’ proboscises, the long, slender, straw-like mouthparts they use to suck nectar from flowers. But lachryphagy is the “most plausible explanation,” the researchers write in the paper. Roughly a year later, a colleague captured video footage that appeared to show the same thing—moths hovering around a moose’s eyes, per Scientific American. Scientists have previously observed moths, bees and butterflies feeding on the tears of other animals. They’ve documented solitary bees drinking the tears of yellow-spotted river turtles in Ecuador, stingless bees harvesting human tears in Thailand, erebid moths feasting on the tears of ringed kingfishers in Colombia and erebid moths slurping up the tears of sleeping black-chinned antbirds in Brazil. But most of these instances have occurred in subtropical and tropical regions. Only one known case of lachryphagy has been documented outside the tropics, according to the researchers: a moth eating the tears of a horse in Arkansas. At first, researcher Laurence Clarfeld didn't know what he was seeing when he spotted moths hovering around a moose's eyes. Vermont Fish and Wildlife Department It may be that lachryphagy is simply more common in the tropics. But it’s also possible that “not a lot of scientists are looking in [other] places,” Akito Kawahara, an entomologist at the Florida Museum of Natural History who was not involved with the research, tells Scientific American. Why do moths and other insects feed on tears? It’s not entirely clear, but scientists suspect they may be seeking out certain essential nutrients, like sodium, during periods when those substances may be harder to find elsewhere. They may also be looking for protein boost. Insects typically get protein from plant nectar, but tears may be a handy backup. “Vertebrate fluids are the main alternative source for obtaining proteins,” Leandro Moraes, a biologist at the University of São Paulo who observed tear-feeding moths in Brazil, told National Geographic’s Sandrine Ceurstemont in 2018. Did you know? Resourceful insects Aside from tears, butterflies and moths have been known to take advantage of whatever resources are available, gathering up nutrient-rich liquids in and around soil, feces and carrion, including sweat and blood. Scientists call this feeding behavior “puddling.” Though lachryphagy appears to be relatively rare in nature, researchers still want to learn more about this unusual behavior. The tear drinker obviously benefits, but what about the tear supplier? For now, the relationship appears to be fairly one-sided—and might even be harmful to the host. In moose, for instance, eye-visiting moths could be transmitting pathogens that cause keratoconjunctivitis, which can lead to eye lesions and “significant health impacts,” the researchers write in the paper. For now, though, that’s just a hypothesis. Now that tear-drinking has been observed outside its typical range, the researchers are curious to know where else this behavior might be taking place, and among which other species. They’re encouraging wildlife scientists to keep an eye out because lachryphagy might ultimately be “more widespread than the lack of past records would suggest,” they write.

Costa Rica Shifts Toward Regenerative Tourism Alongside Other Nations

Costa Rica has long stood out for its commitment to protecting natural areas through tourism. Now, our country joins a growing number of nations that push beyond basic protection. They aim to restore and improve ecosystems damaged by past activities. This approach, called regenerative tourism, changes how visitors interact with places they travel to. In Costa Rica, tourism generates over 8 percent of the national economy and supports hundreds of thousands of jobs. For decades, the focus stayed on sustainability—keeping beaches clean, forests intact, and wildlife safe without causing more harm. But recent efforts show a clear move to regeneration. Local projects work to rebuild habitats, boost biodiversity, and strengthen communities hit hard by environmental changes. Take Punta Leona, a coastal area in Puntarenas. Hotels there add a small fee to each booking, with funds going directly to conserve local plants and animals. This has helped protect scarlet macaws and other species facing threats from habitat loss. In the Arenal area, Rancho Margot operates as a self-sustaining farm and lodge. It grows its own food, recycles water, and teaches guests how to plant trees that restore soil eroded by old farming practices. These actions do more than maintain the status quo; they repair what was lost. Costa Rica’s government backs this trend. The Tourism Board promotes programs that encourage visitors to join conservation work, such as planting mangroves along the Pacific coast or monitoring sea turtles in Tortuguero. A group called Costa Rica Regenerativa advises businesses on how to integrate regeneration into their operations. They focus on holistic plans that cover social, cultural, and environmental needs. As a result, areas like Monteverde see improved cloud forest health, with reforestation efforts bringing back native species absent for years. This shift aligns with global patterns. New Zealand sets a strong example. Its tourism authority invites travelers to participate in restoring native forests and waterways. In places like Rotorua, canopy tours fund projects that remove invasive plants and protect geothermal sites. The country reports higher visitor satisfaction when people contribute to these efforts, leading to longer stays and more repeat trips. Saudi Arabia takes a different path but shares the goal. It invests in large-scale regeneration in desert regions, turning arid lands into green spaces through water management and planting programs. Tourism there now includes experiences where guests help with these restorations, drawing interest from eco-conscious travelers. Finland emphasizes carbon neutrality in its northern landscapes. Cities like Helsinki offer tours that involve cleaning up lakes and planting boreal forests. This not only offsets travel emissions but also enhances wildlife corridors for species like reindeer. Ecuador’s Galápagos Islands provide another case. Strict rules limit visitor numbers, but regenerative programs let people assist in removing invasive species and monitoring marine life. Revenue from these activities funds habitat restoration, helping giant tortoises and other endemic animals thrive. In Mexico, Playa Viva on the Pacific coast runs as a regenerative resort. It restores mangroves and coastal dunes while involving local communities in decision-making. Guests leave with a sense of having improved the place they visited. These examples show regenerative tourism spreading across continents. It responds to rising awareness of climate change and biodiversity loss. Travelers today seek meaningful trips that give back, and nations like Costa Rica benefit from this demand. Studies from the World Travel & Tourism Council indicate that regenerative practices can increase tourism revenue by up to 20 percent in participating areas, as they attract higher-spending visitors. Challenges remain. Mass tourism can strain resources, as seen in some Costa Rican beaches where overcrowding leads to pollution. To counter this, experts call for better regulations and education. Community involvement stays key—local people must lead these initiatives to ensure they meet real needs. Looking ahead, Costa Rica plans to expand regenerative models nationwide. Partnerships with international organizations aim to share knowledge with other countries. This positions the nation as a guide in the field, showing how tourism can heal rather than just preserve. As more nations adopt this model, the travel industry may see lasting change. For us here in Costa Rica, it means building a healthier future for our land and people.

In Alaska’s Warming Arctic, Photos Show an Indigenous Elder Passing Down Hunting Traditions

An Inupiaq elder teaches his great-grandson to hunt in rapidly warming Northwest Alaska where thinning ice, shifting caribou migrations and severe storms are reshaping life

KOTZEBUE, Alaska (AP) — The low autumn light turned the tundra gold as James Schaeffer, 7, and his cousin Charles Gallahorn, 10, raced down a dirt path by the cemetery on the edge of town. Permafrost thaw had buckled the ground, tilting wooden cross grave markers sideways. The boys took turns smashing slabs of ice that had formed in puddles across the warped road.Their great-grandfather, Roswell Schaeffer, 78, trailed behind. What was a playground to the kids was, for Schaeffer – an Inupiaq elder and prolific hunter – a reminder of what warming temperatures had undone: the stable ice he once hunted seals on, the permafrost cellars that kept food frozen all summer, the salmon runs and caribou migrations that once defined the seasons.Now another pressure loomed. A 211-mile mining road that would cut through caribou and salmon habitat was approved by the Trump administration this fall, though the project still faces lawsuits and opposition from environmental and native groups. Schaeffer and other critics worry it could open the region to outside hunters and further devastate already declining herds. “If we lose our caribou – both from climate change and overhunting – we’ll never be the same,” he said. “We’re going to lose our culture totally.”Still, Schaeffer insists on taking the next generation out on the land, even when the animals don’t come. It was late September and he and James would normally have been at their camp hunting caribou. But the herd has been migrating later each year and still hadn’t arrived – a pattern scientists link to climate change, mostly caused by the burning of oil, gas and coal. So instead of caribou, they scanned the tundra for swans, ptarmigan and ducks.Caribou antlers are stacked outside Schaeffer's home. Traditional seal hooks and whale harpoons hang in his hunting shed. Inside, a photograph of him with a hunted beluga is mounted on the wall beside the head of a dall sheep and a traditional mask his daughter Aakatchaq made from caribou hide and lynx fur.He got his first caribou at 14 and began taking his own children out at 7. James made his first caribou kill this past spring with a .22 rifle. He teaches James what his father taught him: that power comes from giving food and a hunter’s responsibility is to feed the elders.“When you’re raised an Inupiaq, your whole being is to make sure the elders have food,” he said.But even as he passes down those lessons, Schaeffer worries there won’t be enough to sustain the next generation – or to sustain him. “The reason I’ve been a successful hunter is the firm belief that, when I become old, people will feed me,” he said. “My great-grandson and my grandson are my future for food.” That future feels tenuous These days, they’re eating less hunted food and relying more on farmed chicken and processed goods from the store. The caribou are fewer, the salmon scarcer, the storms more severe. Record rainfall battered Northwest Alaska this year, flooding Schaeffer’s backyard twice this fall alone. He worries about the toll on wildlife and whether his grandchildren will be able to live in Kotzebue as the changes accelerate.“It’s kind of scary to think about what’s going to happen,” he said.That afternoon, James ducked into the bed of Schaeffer’s truck and aimed into the water. He shot two ducks. Schaeffer helped him into waders – waterproof overalls – so they could collect them and bring them home for dinner, but the tide was too high. They had to turn back without collecting the ducks. The changes weigh on others, too. Schaeffer’s friend, writer and commercial fisherman Seth Kantner grew up along the Kobuk River, where caribou once reliably crossed by the hundreds of thousands. “I can hardly stand how lonely it feels without all the caribou that used to be here,” he said. “This road is the largest threat. But right beside it is climate change.”The Associated Press receives support from the Walton Family Foundation for coverage of water and environmental policy.
