Don’t waste your money these don’t work.
I was hopeful based on reviews that these would work for me. They claim to help rid a variety of pests, my apartment I just moved in to came with a cockroach infestation and rodents in my walls. I didn’t expect it to work for the roaches that would have been too good to be true in my opinion, and it didn’t make a dent. However I did expect some results for the rodents in my wall. I was always hearing them in the same spot which happened to be right by an outlet so I plugged it in there. It didnt do anything to deter them. All I noticed was I was hearing the beeping/ticking noise as it emitted into the walls. If I had been able to move I would be contacting a personal pest control company not trying something like this again.
