Are Ultrasonic Pest Repellents Safe for Pets? What Every Pet Owner Should Know.
At PESTFREEHOME, we’re committed to humane pest control that protects your home — without putting your pets at risk. One of the most common questions we receive is:
“Are ultrasonic pest repellents safe to use around pets?”
The short answer is: Yes — but with important considerations depending on the type of pet.
In this guide, we’ll walk you through everything you need to know about using ultrasonic repellent devices safely around:
- Dogs and cats
- Rabbits, hamsters, guinea pigs, and other small mammals
- Birds, reptiles, amphibians, and exotic pets
Ultrasonic Pest Repellents and Dogs
Most ultrasonic pest repellers operate at frequencies between 20 kHz and 65 kHz, which are generally above the hearing range of adult humans — but well within the range of dogs.
Will it harm your dog?
No — ultrasonic waves are non-lethal and do not cause physical harm. However, dogs can hear the sound, and some may react to it with curiosity, discomfort, or stress, especially in quiet environments.
Best Practice:
- Observe your dog’s reaction when the device is first plugged in
- Use in open or larger rooms where the sound is more diffused
- If discomfort occurs, reposition the unit or switch the modes.
We recommend AMZ BRAND ( HX188 ) Ultrasonic Repellents that offers 4 different strength modes starting from Quiet Mode ( Mode 1 ) to Ultra High Mode ( Mode 4 )

Ultrasonic Pest Repellents and Cats
Cats also have an excellent sense of hearing, with sensitivity to higher frequencies than humans.
Do cats mind ultrasonic repellents?
In general, cats are less reactive than dogs to these sounds. However, very sensitive or anxious cats may still notice and be bothered by prolonged exposure.
Best Practice:
- Avoid placing the unit near their favourite resting areas.
- Monitor for subtle behavioural changes like hiding or pacing
- Opt for less powerful models to minimize disturbance
We recommend our own PESTFREEHOME ( PFH88 ) Ultrasonic Repellents that offers 2 different strength modes starting from Auto Mode ( On and Off ) and Mode 2 ( Consistent ) - both modes are quiet and less powerful for pets such as cats, yet still very effective for mice.

Small Pets: Rabbits, Hamsters, Guinea Pigs & Ferrets
Small mammals like hamsters, rabbits, and guinea pigs have high-frequency hearing ranges and may be more affected than cats or dogs.
Important Considerations:
- These animals are more prone to stress from environmental changes, including sound.
- Chronic exposure could potentially cause anxiety or interfere with natural behaviours.
Best Practice: ( if Ultrasonic Repellent is used )
- Keep ultrasonic units well far away from cages or enclosures
- If possible, use repellents only in areas where small pets are not housed
- Choose alternative options such as Repellent Sprays.
We recommend natural non-toxic Rodent Repellent spray ( Purchase Here ) starting only from £10.48 / per 100ml bottle Free UK delivery inc.
or much more affordable option in the long term - 50ml of Pure Peppermint Mixture to be mixed with water ( Makes 40L of Effective Solution ) and includes free UK Shipping.

Exotic Pets: Birds, Reptiles, Amphibians & More
Exotic pets have wildly different auditory sensitivities depending on species.
- Birds ( especially parrots ) can detect ultrasonic frequencies and may find them stressful.
- Reptiles and amphibians typically do not hear in ultrasonic ranges — but sound-wave occurred vibrations can still be disturbing
Best Practice:
- Always research your specific pet species
- Avoid placing devices near terrariums or aviaries
Consult with a vet or exotic pet specialist if in doubt
We recommend natural non-toxic alternatives such as Peppermint Scented Repellent Spheres ( Purchase Here ) or any other Natural Repellent Spray / Solution.
General Tips for Pet-Safe Use
- Choose Ultrasonic Pest Repellents that are low power or have adjustable frequencies.
- Always monitor your pet's behaviour in the first ( 24–48 hours ) after installing a new unit or using new solutions.
- Consider other humane and natural pest control methods for more flexibility in pet-heavy environments.
- Never use multiple units in small spaces where animals live or sleep
