Mouse Rodent Rat Spider Roach Repellent Indoor Ultrasonic Pest Insect Bug Repeller, Pest Control Device for Home Basement Attic Garage (4 Pack)

I have tested these ‘repellents’ and can say without a doubt that they do absolutely nothing. I had them next to a new infestation of bats who were not disturbed by them. The stink bugs are still inside the house, the squirrels congregate on the porch, and the ants build a trail right under them. For a couple of weeks, I had three of the units on top of a beam under which the bats were hanging. Given that bats use ultrasonic echolocation, these units did not to seem to interfere. Looks like the joke is on the buyer….

Does nothing at all for moles or spiders. Replaced weather strip on garage door to keep mice out. Noise can be quite loud at times as well but you kind of get used to it.

I have been using this pest repeller for about 2 yrs now. Still the same divice plugged in, its still working! I used to have tons of ants around my cat food bowl cuz I leave the dry food out for them 24/7 to eat in case i didnt get a chance to feed them the wet food yet. This device works like a miracle. The ants are totally gone. The closer to the plug area (around 3 ft farther out the max, or else it wont be as effective) the more effective it is.

Zero effect on roaches, they walk nearby without hesitation and without any harm. The only useful feature is a nightlight that works regardless of effectiveness against pests.

I love that it repels pests without harming my pets or children.No noise or smell, unlike chemical sprays. Very pleasant to use.
