Review on 🪲 2 Pack Home Sentinel Ultrasonic Pest Repellent - Indoor 5-in-1 Pest Control Repeller with Electromagnetic, Ionizer, Auto Light | Effectively Repels Mosquitos, Rats, Spiders, and Rodents by Teri Washington

I am very pleasantly surprised. I bought them with full risk that they wouldn't work. I decided to put two in my garage where I have the most spiders. I figured if I found out if it worked it would surely be in my garage where I would notice the difference. I didn't have any spiders this summer, at least not that I could see them. I always see lots of cobwebs, spider eggs (GUY!) and big spiders, live spiders, dead spiders, but nothing this summer and fall. I didn't see any other bugs in the garage either. I'm sure there might still be some in the dark clutter in my garage, but I didn't see anything: no cobwebs, no bags. Nada. These devices have to work, otherwise it's just a coincidence. My house is surrounded by 40 thujas almost two stories tall and as you may know spiders LOVE living in it so it's not due to a lack of population. I am ordering more for the top level of my home.
