Review on 🐜 6 Pack Ultrasonic Pest Repeller - Electronic Plug-in Indoor Pest Control for Home, Office, Warehouse, Hotel by Dustin Mitchell

Reportedly repels rodents, spiders and other vermin. Well I can tell you it doesn't work as advertised. I put this in my basement and a few days later I noticed a plastic coffee container with the black lid almost completely gnawed off. Looks like mice or rats (most likely mice) tried to get into the bin to get at the rat bait I kept there! Well at least I know the rat bait works but not this thing that was about 5ft from me pointing at the container. Also place this right next to some spiders in my living room. Same result. Nothing. Therefore I do not recommend this product. Doesn't work as advertised. I wish I could get my money back.
