Ultrasonic pest repeller safe for pets

Updated: October 2026

The title says pet safe, the dog is in the kitchen, and the hamster is in the same room as the socket. An ultrasonic pest repeller safe for pets is not a single yes. On these amazon.co.uk listings, pets usually means cats and dogs in the seller’s wording. It does not mean hamsters, gerbils, or every mode. This page is the household, not a price ranking and not a proofing guide. The table is on the [ultrasonic pest repeller comparison](/hub/pest-control/ultrasonic-pest-repeller). Peter F. read the listings and UK sources on 16 October 2026. We did not run a veterinary test. A qualifying purchase can earn us a commission at no extra cost to you.

What the titles mean by pets

Pestbye says it has not been found to affect cats, dogs, birds, reptiles, amphibians, or children, and that it may affect gerbils, hamsters, or chinchillas. TruSky says it is for children, dogs, and cats, and not for hamsters. A title that only says pet safe has not copied that sentence. Siyuio’s title says safe for pets, then splits the modes: blue when pets are around, red when the house is empty. VNEED says the output is inaudible to people and pets, which the click in the reviews puts in doubt, and it does not mention hamsters. The BLIAZAY four-pack has no pet warning. Silence is not a clearance for a cage. If a hamster, gerbil, rat, or guinea pig lives in the home, do not put the plug in that room. Mode tables, if you are still choosing, are on the buying guide.

Modes people and pets can hear

Some rodent settings are specified where people can hear them. FunBean’s red mode is 10–15 kHz, and the bullet says not to use it with people or pets indoors because it is uncomfortable noise. TruSky’s pressure mode is 1–20 kHz, and reviews describe a high-pitched sweep. Siyuio’s red mode is for an empty house, and one review says children heard a stronger setting the adult did not. If the room is occupied, leave those settings off. Where the socket goes overnight is on the how to use page.

Dogs, cats, and the published hearing ranges

Rentokil publishes ranges that show why a dog is not outside this sound: humans roughly to about 23 kHz, dogs to about 45 kHz, cats to about 64 kHz, at Rentokil’s hearing figures. Siyuio prints 20–100 kHz. A dog’s published range reaches about 45 kHz, so you cannot say dogs hear none of these units. Those figures are not a veterinary trial of these ASINs. If a dog leaves the room or will not settle on a particular mode, switch that mode off. If you want a medical view, ask a vet.

Night lights and clicks

A unit can bother a room without being a loud tone. VNEED’s text says the output is inaudible, and reviews repeat a click and a blue light at night, with no mode to turn the click down. One BLIAZAY model 218 review calls the indicator a little bright in a bedroom. Siyuio reviews call the blue glow bright if it faces the room, on the mode suggested for bedrooms. If the dog sleeps there, move the socket, turn the unit, or leave that plug out of the room.

Safe is not the same as effective

A careful pet line is not evidence that mice or insects leave. The Advertising Standards Authority has yet to accept an efficacy claim for these devices, and testimonials are not enough. Pestbye can print a long list of animals and still have reviews that say the mice came back. If the job is rodents, the mice page says the plug does not close the hole. Do not use an ultrasonic deterrent in or near a bat roost. Nothing here is a reason to leave a hamster in the room to see what happens. The cage moves, or the plug does not go in.

Common questions

Is it safe for dogs?
Sellers who mention dogs mean dogs, and that is not a test of these plugs. Rentokil’s published dog range reaches about 45 kHz, and several units state bands that overlap it. One Siyuio review says a dog did not react on the quiet mode. Watch your own dog and switch the mode off if the animal is unsettled. Ask a vet if you need a medical view.
What about hamsters, gerbils, or pet rats?
Do not use these plugs in that room. Pestbye says it may affect gerbils, hamsters, or chinchillas. TruSky says not around hamsters. The BLIAZAY four-pack never mentions rodent pets, which is not a clearance. Pet safe on a title is the dogs-and-cats wording, not a line you can stretch to a cage.
Why can you hear a mouse repeller if it is ultrasonic?
Because some modes are specified in a band people hear. FunBean’s red mode is 10–15 kHz. TruSky’s pressure mode is 1–20 kHz. On Rentokil’s figures, human hearing runs to about 23 kHz. REPELIX also warns that sensitive hearing may notice the quietest mode. Ultrasonic on the box does not mean every setting is silent.
Which mode should stay on when pets are in the room?
Siyuio says blue when pets are around, and red when the house is empty. FunBean says not to use red indoors with people or pets. REPELIX calls mode 1 the quietest and still adds a sensitive-hearing warning. If the only rodent mode is the one you must switch off, you cannot leave it on beside a dog and call both things true.
Does safe mean the device works?
No. A pet warning can be the most honest sentence on the listing and still say nothing about mice leaving. The Advertising Standards Authority has not accepted efficacy claims for this kind of device on testimonials. If the problem is rodents, proof the holes and read the mice page. A quiet mode a dog tolerates is a household fact, not a clear-out.
