Review on 2021 Upgraded Ultrasonic Pest Repeller: 8-Pack Ultrasound Plug-in Pest 🐜 Control for Home, Office, Kitchen, Warehouse, Hotel - Effective Electronic Insect Repellent by Mayur Kreps

If this technology only worked on small rodents like roaches and ants it would be ideal. The outlets are usually higher than where roaches crawl, and the only two outlets in my bathroom are above the countertop. I can't confirm whether or not this has reduced the movement of roaches, but I will do my best to get them out of my home! Give them a try, every little thing should help, right?
