BORHOOD Ultrasonic Pest Repellent Plug-in, Electronic Mouse Traps & Insect Repellent (Black, 1 Pack)

What buyers think

Buyer-review evidence for this ultrasonic repeller is limited, but the recurring themes are consistent. Multiple reviewers report it was easy to install, quiet during certain modes, and that they saw fewer insects and signs of rodent activity after using it for weeks. Others emphasize the appeal of avoiding chemical sprays and sticky traps.

There is also at least one negative experience suggesting weak performance for roaches, including complaints about noticeable sound during one mode. Overall, buyer sentiment leans toward “easy, non-messy deterrence,” but the evidence is not strong enough to treat this as a guaranteed solution for all insect types.

How it works and what the modes are for

This device uses variable sound waves across an ultrasonic range (25kHz to 65kHz) and offers three operating settings. In practice, that means you are not trapping pests, you are trying to make the area less comfortable for them to stay.

• Pressure Wave and Ultrasonic modes: positioned for daily deterrence and calmer operation.
• Audible mode: intended for more stubborn issues, with guidance to use it only in uninhabited spaces like attics or when you are away.

It also includes an LCD display so you can confirm the active mode and that the unit is working.

Coverage and placement tips that affect results

Ultrasonic repellers work best when the sound can reach where pests are moving and resting. This unit’s guidance notes that ultrasonic waves cannot penetrate solid walls or heavy furniture, so placement matters.

• Use one unit per enclosed room: especially for kitchens, living rooms, basements, and garages.
• Height matters: the recommended placement is roughly 10–50 inches above the floor to help disperse sound.

If you are dealing with pests that are hiding in one specific area, you may get better deterrence by targeting that zone rather than relying on a single unit to “cover everything.”

Power use and day-to-day convenience

For convenience, this is a plug-in device meant to run continuously. It’s rated at about 3–5W and uses the included adapter for 24/7 operation. That makes it easier to maintain than sticky traps or ongoing bait replenishment, since you are not constantly monitoring it for catches.

Family and pet considerations

The design is marketed as a cleaner, trap-free approach suitable for use around children and typical household pets. There is also an explicit note not to use it around pet rodents such as hamsters. If you keep small pet rodents indoors, treat that instruction as a hard stop for your setup.

Pros and cons for common buyer situations

Best for

• Buyers who want a non-chemical deterrent: especially if you prefer plug-in operation over sprays or sticky traps.
• Light to moderate pest pressure: where you are aiming to discourage pests from settling in living spaces.
• Multi-room prevention setups: if you are willing to place one unit per enclosed room and adjust height.

Who should avoid it

• Roach-focused buyers: review evidence is mixed for roaches, and you may need more established approaches.
• Anyone expecting instant elimination: guidance indicates it usually takes 3–4 weeks for complete results.
• Homes where you cannot control placement: if furniture and walls block access to the pest area, deterrence may be limited.
• Households with pet hamsters or other pet rodents: the product is not intended for that scenario.

Verdict

The BORHOOD ultrasonic pest repellent plug-in is a straightforward, low-effort option for deterrence, with useful features like three modes, continuous operation, and placement guidance. It appears well-suited for buyers who want to reduce insects and help deter rodents without chemicals. However, it is not a guaranteed fix for every pest, and results take weeks, so it makes the most sense for prevention and discouragement, not immediate eradication or roach-heavy infestations.

FAQ

How long does it take to see results?

It’s typically expected to take 3–4 weeks for complete results. An initial increase in activity during the first week can be part of the deterrence process as pests leave their nests.

Does it work through walls and furniture?

No. Ultrasonic sound waves cannot penetrate solid walls or heavy furniture, so you may need one unit per enclosed room and should place it according to the recommended height.

Is it safe for pets?

The device is designed to be used around children and typical household pets. However, do not use it around pet rodents like hamsters.

Which mode should I use for daily pest deterrence?

The quiet Pressure Wave and Ultrasonic modes are intended for daily use. The audible, “power” mode is intended only for uninhabited spaces like attics or when you are away from home.

Is this good for roaches?

Buyer feedback is mixed for roaches. If roaches are your primary concern, you may want to consider more proven control methods rather than relying on an ultrasonic deterrent alone.

What power does the plug-in use?

It consumes about 3–5W, using the included adapter for 24/7 operation.

Where should I place the unit?

Place it about 10–50 inches above the floor to help sound dispersion, and target enclosed rooms where you want deterrence.
