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.

I have used a similar item in the past. and they just now wore out. I had them approximately t years just noticed field mice coming in so I bought the 6 pack option. Inwill probably buy a other y pack just to put them in every room and two closets in my house. Much better than mouse traps and no odor from messy traps.

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!

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.

They are working great at keeping the mice out of my house, and a bonus is they are working great at keeping flies out of my home also. I love these and will definitely keep buying them!

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,

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.

It keeps the pests away but makes a clicking noise. I should have read the label online more closely and researched this product before buying it.

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.
