Electronic & Ultrasonic Rodent Repellers

Electromagnetic units send pulses through your home’s electrical wiring, so the effect is not confined to the room the unit is plugged into in the way an ultrasonic unit is. Manufacturers state coverage per unit on the packaging - follow that figure rather than assuming whole-house coverage.

Repellers are a supplementary layer rather than a treatment on their own, so we would not expect them to clear an infestation. Use one alongside proofing and trapping, and judge progress by what the traps are catching rather than by the unit itself.

They are not suitable for households with pet rodents - hamsters, guinea pigs, gerbils, rabbits and chinchillas hear in the same range and may be distressed. Cats, dogs and birds are generally unaffected, but check the manufacturer’s guidance and place the unit away from any pet’s sleeping area.

No. Ultrasonic sound will not travel through walls, furniture or solid objects, and soft furnishings absorb it. Place the unit in an open area free from obstructions, and use separate units for separate rooms.

No - treat a repeller as an extra layer alongside the things that actually clear an infestation. Close the entry points with proofing first, then clear what is already inside with traps or bait. A repeller on its own will not resolve an active problem.

Once you’ve eliminated the rodents, prevention is key. Use rodent proofing products to seal entry points in your home, store food in airtight containers, and regularly clean up food debris. We also offer rodent repellents that create a barrier to help prevent future infestations.

No. These units contain no active substance - they plug in and run on mains power. If you want to avoid poison across the whole job, pair one with snap or electronic traps and physical proofing.
