Review on 🐜 2021 Upgraded Ultrasonic Pest Repeller Plug-In - Indoor Electronic Pest Repellent for Fly, Bug, Cockroach, Spider, Mouse, Rat, Bat, Squirrel, Mosquito - Safe for Pets by Amber Westbrooks

I'm skeptical of good reviews as they all seem to be 'instant results' but the description says it takes a few weeks as the pet grows for the first few days. We had our week due to a recent infestation behind our shower screen. I didn't see any pests because I cleaned the area thoroughly and sprayed it with bug spray. When the item arrived and there were no errors, I wasn't sure what to thank it for. A few days later, the creatures appeared. Being a bathroom nothing really bothers, so I doubly doubt it does anything at all. Unfortunately, if I follow the manufacturer's recommendation to wait a few more weeks, the return window should close. Unfortunately, with roaches, just a few days can spell disaster because they are so prolific. Pooh. Discussion give it another week and come back to this review.
