ISUDA [2018 Upgraded] Ultrasonic Pest Repeller Plug in Pest Control with LED Night Light- Pest Repellent for Mosquito,Rat,Flea,Fly,Roach,Spider - Non-Toxic Environment-Friendly, Humans & Pets Safe.

Worked okay for a few months. After four months I started finding a few centepides a week very near the devices.

I buy this for Roach in my kitchen. Roach still have some, but not many than before.

Works great! have not seen another spider, roach or ants! we had a HUGE ant problem and now they are all gone! Love this!

Haven seen any bugs seems to work

This is a very clean and easy way to repel bugs and rodents without it being a scary venture.

WTFly???? I never write reviews but this one warrants it. Every summer we pull out fly spray and yucky fly paper that only shows off the grossness of the fly problem we have here in the Texas hill country during hot summers. On a desperate whim, I ordered this device. When I plugged it in we have 5 flies zooming around and a fly paper with 10 nasty flies stuck to it. I don't know where those 5 flies went but I have not had a live fly in the house since (?!?!?!). REALLY. Occasionally, I will find a dead fly on the sill or see a fly zoom by but then they "go away". KrAzY but Im so happy. I am going to order another to put outside for mosquitoes in the summer. Best product ever. K

Haven't seen any critters since putting these in my house.

Does not work!
