Ultrasonic Pest Repeller, 2 Pack Electronic Pest Control Plug in Indoor Pest Repellent for Mice, Bed Bugs, Mosquitoes, Roaches, Spiders, No More Insect Sprays, 100% Human & Pets Safe

Good value twin pack of pest repellers, which I purchased to deter eight legged freaks from entering my house!!!! I've been using them for over a month now and, so far, they seem to be doing the job. We have one in our living room, and the other on our upstairs landing. The ultrasonic waves are inaudible to humans, so you don't even know they're there to be honest. We don't have any pets ourselves, but our neighbour's dogs have not been affected in any way. Very satisfied with my purchase! Thanks.

We had been having a problem with mosquitos and sandflies so I purchased these and put one in my bedroom and the other in the living room. These do absolutely nothing. They are glorified night lights. Even with the pest repellers on I could see the presence of flies, spiders and other insects in the rooms and they were acting normally. Do not waste your money.

Used to keep spiders at bay as I am arachnophobic .

Seems to work bought country house flys were a night mare ,so a big difference in fly coming into house,very neat looking

Happy with my purchase, seems to be working even after a year.

does not help either from insects not from mice :(

Excellent product.

stopped all mosquitoes and may be reducing the spider invasion...
