Review on Joerry Ultrasonic Pest Repellent - Enhanced Bug Repeller Plugin (6 Packs) by Amber Gaiser

I ordered these because I had a problem with cockroaches coming through the vent every time I cooked (or showered for some reason). They seemed to be chasing the smell of food, but they tried with all their might to get at it. The day after I cooked something, I found dead cockroaches. It was terrible. I sent them away, stuck one in the bathroom they went into, and haven't seen anyone alive or dead since. It's been almost a month now. Seems to be working fine. I ordered six packs but have only needed one so far. I would advise anyone to get these if you have a similar problem.
