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 Eddie Tyson

My husband and I tried almost every spray available and found this one. We were skeptical at first but they worked for us. Just plug into an outlet and boom. Ready. We saw a small increase in bugs, but then we just didn't see them. So they don't fix the problem right away and don't seem to work. trust them They are. Soon you will think. Why haven't I seen any errors lately? You can even plug them into an external outlet. We recently moved and we collected them too and they moved with us. If you're wondering whether or not to trust them at such a cheap price, then there's not much to lose. I've seen other reviews saying spiders crawl over it or mice crawl right under it. I'm not sure what area they were in, but I didn't see it from ours. In most cases we found dead insects under the device. Also, all the insects we found were already dead when they started working. They pull out all the insects hiding in your house. It's better outside than inside! They work. They may just take longer to work than you expect as it's a different deterrent than just spraying.
