Review on Aerith Ultrasonic Electronic Repellent Cockroaches by Heather Martin

I would like to say that I have noticed a definite improvement. I recently experienced the worst infestation of roaches and mice in my home in 30 years. I now realize what happened. But in an attempt to eradicate the problem by spending tons of money on other products. I bought it. Noticed improvement almost immediately. But definitely in 3-4 days! So it's been about 3 weeks. From time to time I see here and there what I would call children. My living space is about 1000 square feet including my garage. I spend a lot of time there as I use it as my workshop. It's plugged in and just a few steps away from my "heated" living space. My house has two floors and I rent the top floor. I have 1 unit in each bedroom (about 200 units each), 1 in my bathroom and 2 in my garage. I am so pleased with the results that I have just ordered and received my second box. I ordered my friends upstairs to put one in each bedroom (3/2) and 18 in each bathroom. I placed 1 in the dining room open to the kitchen and 1 on the landing leading up or down. I feel like I've got enough coverage now. I'll update later with the progress above. But now I'm happy to report successes with them. Highly recommended as I bought a second box.
