Ants can be a nuisance in and around the home, invading kitchens and pantries in search of food. While ants pose no real threat to human health, they can contaminate food and trigger allergic reactions in some people. As such, many homeowners turn to chemical ant repellents and baits to control ant infestations. However, if you have cats, you may wonder if these products are safe to use around your furry friends. In this article, we’ll explore whether ant repellents and baits contain ingredients that are toxic to cats.

Are ant repellents toxic to cats?
The short answer is that some ant repellents and baits contain ingredients that are toxic to cats and should be kept away from them. However, not all ant control products pose a risk. Much depends on the specific active and inert ingredients used.
Some of the most common active ingredients found in ant repellents and baits include:
- Pyrethroids – synthetic versions of pyrethrins found in chrysanthemum flowers. Often used in sprays, dusts, and ant traps.
- Neonicotinoids – a relatively new class of insecticides based on nicotine. Found in ant baits, gels, and granules.
- Borates – minerals that act as stomach poisons. Used in gels and powders.
- Fipronil – disrupts the central nervous system of insects. Used in some spot treatments and baits.
Of these active ingredients, pyrethroids and borates are most concerning for cats. Cats lack certain liver enzymes that help metabolize and detoxify these compounds. As a result, exposure can lead to drooling, tremors, and even seizures in cats. Neonicotinoids and fipronil are generally less toxic but can still cause vomiting, lethargy, and other symptoms if ingested.
Inert ingredients may also pose hazards. For example, ant baits often contain sweeteners or fats to attract ants. Xylitol is a common sweetener that, while safe for humans, can cause liver damage and low blood sugar in cats.
So in summary, products containing pyrethroids, borates, xylitol, or unspecified “inert” ingredients should generally be avoided if you have cats. Always check labels carefully and keep cats away from areas treated with ant repellents. Consult your vet if you have any concerns.
Are some ant repellents safer for cats?
Fortunately, not all ant repellents and baits contain ingredients toxic to cats. Some safer options include:
Diatomaceous earth
Diatomaceous earth is made from the fossilized remains of diatoms, a type of hard-shelled algae. The powder works by absorbing lipids from the exoskeleton of ants, leading to dehydration and death. Diatomaceous earth is non-toxic to cats, although inhalation can cause minor lung irritation. Avoid breathing in dust when applying.
Botanical repellents
Certain plant oils like peppermint, citrus, and eucalyptus have natural insect repellent properties. Products based on these botanical ingredients are typically safe for cats when used as directed. Just avoid getting oils on your cat’s fur, as they can be irritating upon grooming.
Boric acid
Though borates are toxic, boric acid is safer at low concentrations. It acts as a stomach poison for insects but is far less toxic to mammals. Use bait stations to limit access. Avoid letting cats ingest powder directly.
Food-grade diatomaceous earth
Make sure to buy food-grade diatomaceous earth, distinguished by low crystalline silica content. Crystalline silica can cause lung damage but food-grade products are safe when used as directed around pets. Still, take care to minimize inhalation.
Desiccant dusts
Dusts like silica aerogel and synthetic amorphous silica kill ants by absorbing their outer waxy layer, causing dehydration. These desiccant dusts are non-toxic for cats and can be applied in walls, cracks and crevices. Avoid leaving piles where curious cats may ingest them.
In summary, there are several ant repellents and baits that use ingredients considered safe for cats when manufacturers’ directions are followed. Check labels and consult your vet if ever unsure.
Tips for using ant repellents safely around cats
If you need to use ant repellents that contain potentially harmful ingredients, there are some precautions you can take to use them safely around cats:
- Carefully read product labels and research all active and inert ingredients.
- Look for low-dose bait stations rather than loose granular bait that can be ingested.
- Avoid spray and dust formulations which are more likely to stick to cat’s fur.
- Apply products in areas inaccessible to cats, like within wall voids.
- Use pet-safe barriers to temporarily block access to treated areas.
- Wipe down or remove granules/residue in areas cats can access once ants are controlled.
- Bathe cats if they come into contact with repellents before they can groom themselves.
- Monitor cats closely for any signs of illness and contact your vet immediately.
With some smart precautions, you can eliminate ants in your home while keeping your cats safe from harm. But your best option is always to use repellents made with cat-safe ingredients whenever possible.
Natural home remedies to repel ants safely around cats
In addition to commercial low-toxicity products, some natural home remedies can help deter ants without putting your cats at risk:
Keep kitchen surfaces clean
Thoroughly clean up any crumbs or spills that can attract foraging ants. Pay special attention around pet bowls.
Store food in sealed containers
Keep pantry items and pet food in airtight containers made of glass, plastic or metal. Ants can chew through paper and cardboard.
Use essential oils
Dab cotton balls with peppermint, eucalyptus or tea tree oil and place along ant trails or potential entry points like windows. Oils deter ants without harming cats.
Spread coffee grounds
Used coffee grounds sprinkled around the outside of your home create an unpleasant texture and odor trail that repels ants. Avoid using directly in gardens.
Plug up cracks and crevices
Seal as many holes and cracks where ants may enter with caulk or pet-safe sealant. This forces them to use exposed trails you can monitor.
Apply vinegar
White vinegar wipes out ant trails by removing pheromones. Mix equal parts vinegar and water in a spray bottle. Reapply every few days until ants are gone.
Draw lines with chalk
Chalk line barriers across trails or around containers disrupts the ants’ scent path. The calcium carbonate abrades their bodies. Reapply after rain or watering.
Sprinkle chili powder
A light dusting of chili powder repels ants and deters them from returning. Focus along trails and entry points but avoid direct contact with plants.
Conclusion
Ant repellents and baits contain a range of active ingredients, some of which are toxic if ingested by cats. Products containing pyrethroids, borates, xylitol, or unspecified inert ingredients should be avoided if you have feline companions. However, alternatives like diatomaceous earth, boric acid bait stations, and desiccant dusts are effective while posing little risk to pets. Exercise caution with any ant control product and always inspect labels thoroughly before use. Implement pet-safe barriers as needed and monitor your cats closely during treatment. With prudence, ant invasions can be safely eliminated without putting your cats in harm’s way.
