Review on 🐜 2020 Upgrade Ultrasonic Pest Repeller 6 Pack: Best Indoor Repellent for Children and Pets Safety, Electronic Pest Control for Mosquitoes, Mice, Cockroaches, Rats, Bugs, Spiders, and Ants by Chris Sharma

I decided to try ultrasonic pest repellent as the weather is getting warmer and it comes 6 units in a pack. I was very glad to try it because I had problems with water bugs. I hate using sprays so I put a pest repellent in every room to keep them from crawling around my house. To this day I haven't seen any crawling bugs or other creepy crawly things. These repellers are small and have a night light. They are easy to use, you just plug them into an outlet, with no batteries, noise or smell. These devices really work, I highly recommend them.
