KOEPUO Ultrasonic Pest Repellent, Plug In Pest Repeller Electronic Pest Control for Roaches, Bugs, Ants, Spiders, Fleas, Mice, Mosquitoes and Other Insects Rodents, Non-toxic Eco-Friendly (4 Pack)

Picked this because of the reviews yet when I tried, nothing happened. Plugged them in around the ground floor of the house and nothing happened, still got mice coming into the kitchen. Only way we stopped the mice was ultimately by going round and meshing up any air bricks they were getting through and as a result, still have one round the back of the cooker. Obviously the noise doesn't bother Mickey as he's still there with no sign of leaving by himself.

This does not get rid of insects, but it greatly disturbs them. Plug these in and the insects will move from their hides.I had a silverfish problem in a house I recently moved into. My advice, know your enemy! I learned where they are likely to hide, I researched the best products for getting rid of them.Important! Set your traps before using these plugs. I sprayed all of the areas these things come out of with really powerful insecticide. I stuck the plug in and honestly, the walls came alive! These buggers where everywhere! It was like a scene from a horror film.The next day I must've scooped up 70 dead ones. This went on for a week. I haven't seen one for an entire month since. I'm going to respray the house once a month to be sure I've got them all.

Don't waste your money. The light of one of the plugs stopped working after 4 weeks. But to be honest it wasn't apparent that any of them were working as the mice problems continue!

I get bitten everywhere I go, but these worked a treat even in Africa in Safari Tents / accommodation. Not one bite -Yippee!

Evidence suggests these do not work - 1 x rat & 1 x mouse in 2 days, - note unit with blue LED.

A very useful pest repellent. I brought this item as my neighbour is in the process of renovation works. No longer seeing any little pests.

Dont work

Don't think they are much good
