Accellorize Pest Control Ultrasonic Repeller, Electronic Mouse Repellent Plug In for Insects, Mice, Rats, Spiders, Roaches, Ants, Bugs, Flies, Fleas, Mosquitoes, Environment-friendly [3-Pack]

Can't give these a full 5 yet because it's only been a few weeks since I got them for all the gnats and spiders I have and crickets oh my... But It must be working because I have several dead ones from time to time away from these plugs and literally have only noticed the gnats or little flies that come in at night when we open the door.Overall they make no sound, love the back light especially in the bathrooms and hallways for my little ones.

It's been about a week, I plugged in these units. Really can't say if there is a difference from the pest control perspective. The rating is based on the basis, that all the units worked and there was no cat or other pet noise.

These don’t do anything. We have had them up for over a month and still nothing has changed

Sorry but this product doesn't work.. i have had it up for almost 2weeks. But see no reduction in the cockroaches..
