Review on 🐛 Ultimate Indoor Pest Control: 6-Pack Ultrasonic Pest Repeller - Mosquito, Mice, Roach, Spider, Insect Repellent, Effective Electronic Plug-In Solution by Everett Underberg

Got them because my MIL has them and I swear by them. After seeing a few spiders in my house I figured it would be cheaper than burning my house down and starting over. Got them, hooked them up, the spiders were gone. Did it work? Maybe. Are you still connected? Yes. I don't risk anything. Also SN: The instructions were hilarious. "In the beginning you might see a large number of insects because they are ready to attack." I say 100% that you should read the instructions.
