Ultrasonic Pest Repeller 4-Pack – Indoor Electronic Insect & Rodent Control for Home, Kitchen, Office

I can't believe how well these work. Amazing. Worth the money. They arrived next day via Walmart and the driver followed my delivery instructions and notified me when it was delivered. I will surely use the Walmart shopping app on a regular basis.

These pest repellers perform as well as the so called "big name" brands" and are very effective at keeping the house free of mice, riaches and ants as well.

so far so good! haven't heard any noise in the walls, as soon a i plugged them in the mice seemed to disappear. the only thing i don't care for is the clicking noise the unit makes. but I'll take that over mice any day!

I am very satisfied with this item. It works just as it is described. I would recommend it to anyone who is wanting to deter pest,

I bought as a precaution of mice coming inside for winter , didn't have any and didn't want any

Does as advertised, keeps mice at bay, no running across the floors, or fumbling in your pantry, but the effect doesn't carry into your homes walls so is limited to driving the pest completely out of the structure. I had to puchase Mighty Mint peppermint spay to drive , the rodents from my home. But use these to ensure they don't return. Another item the ultrasonic do make a chirp , and its audible, but to me it's not a nuisance.

haven't seen any in the house since getting these

I realize it takes a little time to become effective but the mouse don't seem to be affected at all.

it doesnt work i have had all four plugged into a 35ft rv and mice are still running around day and night.

They Didnt Work AT All
