Used to love it

This was my fav app to annoy my young neighbors in the morning after they’d been loud all night. Now I can hear the human repell? Not trying to repell myself too.

После того как включил, пришли тараканы человек 100 и попросили меня поставить лайк этому приложению, значит работает.

Doesn’t Work

Saw a mouse run under a mobile cabinet in my kitchen. Heard it eating on something. I started the Repeller on rodent setting and put my phone on the floor next to the cabinet. The mouse continued doing what was doing without noticing the sound.
