Review on 🐭 Merratric 6 Pack Electronic Ultrasonic Pest Repellers - Indoor Plug in Pest Control Repellent for Mice, Cockroach, Spider, Ant, Mosquito, Bug, Insect - Ultrasonic Technology by Laurie Garcia

Blackbirds and sparrows nest in our walls and ceilings. It's no exaggeration to tell you that the chirping stopped the moment I plugged them into an inner wall socket. We think they're gone because we don't hear any more running or light sounds. UPDATE 4/22/2021 Birds and creatures are gone and not coming back. And while the package said nothing about squirting away squirrels, we no longer have the pleasure of hosting on Airbnb the squirrel family that has lived between our second and third floors since we moved into our home in 2017, and even professional exterminators may not Get rid of. So I have to say that these pest control products are now officially in the top 5 best purchases we've made at Revain. Highly recommended!
