Is ant powder safe for pets?

Updated: October 2026

The tub is in the hall, the cat sleeps on the doorstep, and the question was whether ant powder is safe for pets. A yes or no for the whole category would be the wrong answer. Peter F., editor for DIY & tools at productscompared.co.uk, compared the pet sentences on the amazon.co.uk listings captured on 19 October 2026 with the Nippon 150 g label, HSE No 5499, and PDSA’s permethrin advice. No toxicity test was run. A qualifying purchase can earn a commission at no extra cost to you. Prices and scores are on the [ant powder](/hub/pest-control/ant-powder) comparison. Take the sentence on your pack.

The sentences on these packs

Nippon’s bullets say children and pets need not be excluded. The 150 g label does not use that phrase. It says avoid the dust, cover fish tanks and water tanks, and keep powder out of food and drains. Zero In, B08XQLZYFB, says keep cats away during application. Pestshield does not answer pets. PestShield 150 g does say keep the pack from children and off food-contact areas. A deltamethrin Nippon powder, UK-2017-1104, says not to apply it when pets are present. That line does not transfer to permethrin listing B000TASTU4. Steps are on how to use ant powder.

Food, fish, drains and bats

Keep dust out of food, cover fish tanks and water tanks, and keep the tub out of drains. Garden World says the powder is hazardous to bees and stays off soft furnishings and places where water could be contaminated. A pond edge and a worktop both fail. Before a loft or eaves, the Nippon 150 g label says consult, because a bat roost is protected under the Wildlife and Countryside Act 1981. Match the household on the ant powder buying guide.

Cats and permethrin, without mixing products

PDSA describes permethrin as extremely poisonous to cats at flea-product doses, with drooling, tremors and seizures, and usually fatal if untreated. For a flea spray, PDSA says remove animals, wait half an hour, then ventilate. That is not a dose for these ant powders, and this page will not call the tubs safe for cats or claim they kill cats. Zero In already says keep cats away while you apply it. GOV.UK’s warning is about putting a dog spot-on on a cat.

If something has gone wrong

If a cat is drooling, trembling or fitting after a permethrin product, phone a vet the same hour and name the pack. If a person has swallowed powder, use NHS 111, or 999 if they are collapsing, fitting or cannot breathe. Do not induce vomiting. A possible bat roost is a stop. Dust on a bait trail is covered on ant powder versus ant bait.

Common questions

Is ant powder safe for cats?
There is no category-wide yes. Zero In’s listing says keep pets, especially cats, away during application. Nippon’s amazon bullets say children and pets need not be excluded, while the captured 150 g label still says to avoid the dust and to protect water. Pestshield does not answer pets in these saved listings. PDSA’s severe warnings describe flea products and high doses, which we are not equating with these tubs.
Why does Nippon say pets need not be excluded?
That sentence is on the amazon bullets for both Nippon sizes in this set, and Garden World repeats that treated areas have no access restriction, with storage out of reach of children and pets. The Nippon 150 g label we captured does not use that phrase. It still tells you to avoid breathing the dust, to protect fish tanks and water tanks, and to keep the powder out of food and drains. The bullet does not cancel the label.
Why does Zero In say the opposite?
Zero In’s amazon listing tells you to keep pets, especially cats, away during application, and the manufacturer’s 450 g page says to remove pets, particularly cats. Nippon’s bullets are more open. The two listings are not one policy. If a cat uses the step, Zero In’s sentence is the one you can follow only by keeping the cat off that step while you apply the dust.
What about a fish tank or a pond?
Cover fish tanks and water tanks before you treat nearby, which is the Nippon 150 g instruction. Garden World also says to keep the powder away from places where water could be contaminated. A crack beside a garden pond is a poor place for a dust that can blow or wash in. Drains are out as well: the same label says not to empty the tub into them.
Is permethrin ant powder the same as a dog flea spot-on?
They can share the active ingredient and still be different products. PDSA and GOV.UK warn that dog spot-ons and similar flea products can poison cats. Those pages do not set a dose for the ant powders in this comparison. Never put a dog spot-on on a cat. For the ant tub, follow the pet sentence on that pack, and treat PDSA’s emergency signs as a reason to call a vet.
What if a child or a pet has swallowed some?
Phone a vet if a pet has swallowed powder or is drooling, trembling or fitting. For a person, use NHS 111, or 999 when someone is collapsing, fitting or cannot breathe. Take the pack with you so the active ingredient is clear. Do not induce vomiting and do not try a home remedy. This page cannot tell you a safe amount.
