Tomu Ultrasonic Pest Repeller for Bugs and Insects, Mice Repellent to Repel and Prevent Mouse, Ant, Mosquito, Spider, Rodent, Roach,Child and Pets Safe Control(4 New Packs)

Did not work. I hoped this would keep flies, knats, and ants away. Instead it keeps nothing away, and i actually have an increase in creepy crawlers. I have used this for 2 months. Waste of money.

At first, my dogs were not barking at mice activity in the kitchen.....now the mice are back. They didn't work so good.

Didn’t work

Haven't noticed a difference. Dont buy.

Seems like all the mice came out of the woodwork! Would not recommend this product. I've never seen a mouse who stays in one's presence like he's part of the family. Ughhh!!!

False claims. Waste of money

Did not keep the mice and roaches away. I'm checking to see if it can be returned.

Really good, I used for cockroaches and it works perfectly.
