400 Ultrasonic Mouse & Insect Control Plug In Pest Repeller 400sq ft Room

I purchased these to try and help deal with a rat that had decided to terrorise me. I discovered, with the rat setting up home in my wall, that I do in fact have a phobia of the things. I plugged these in all round my house and hoped for the best and to be fair activity was reduced for the next two night. Unfortunately this was the sum total of the effect these had. By the third night it was back to tap dancing in the walls and, to my complete horror and leading to a partial breakdown, had also chewed through the ceiling and had gained access into the actual house. I quickly realised my only options were the men in white coats or a professional pest control company. I'm sure you'll be glad to know I'm trying the professional pest control people first. They are now in the case and dealing with the situation. They are a lot more expensive than these plugs were but it turns out the saying "you get what you pay for" is very true.As a side note, if the critter that moved in with you doesn't sent you bonkers the constant clicking these things produce might.So to round up, these don't work and, in my experience, apparently only poison really does. (Please note Cayenne pepper, peppermint etc. are all as much use as a hole in the head also)

Neat gadget. Yet to prove its usefulness.spider has been seen since installation in bedroom. Some people may not like the tick noise but it is quite quiet.

Appears to be working fine

It serves the purpose it was intended for.

I combined these with a repellant that done the whole house and then put one of these in each of the main roomsSo far so good,but they do have a slight clicking so might be unsuitable for bedrooms as the noise may drive you potty

Does not work

Dosent work. Did not solve the problem and unable to get in contact with seller for refund. Don’t waste your time and hard earned money on these they do nothing.

There's a very audible click every 3 seconds which is really annoying. I don't know if the product works or not as I'm sending it straight back.
