I get mice up at the BOL. I put out poison once, but a mouse decided to die right smack in the middle of my living room floor. I kept thinking of all the equally inappropriate yet not NEARLY as conspicuous places a mouse might expire, and it kind of got me off poison.
I have traps, but never set them because either the cat's around, or I'm in a hurry, or I'm about to leave and I don't want the mouse in a week. Just never seems like the time to set traps.
I've been cleaning out my basement and found something I don't remember picking up at a thrift store for a couple bucks.
It has settings for "insects", "rodents", and "insects & rodents", then "quiet" "medium", and "loud"
It's NOT ultrasonic - at least not in the loud and medium modes. they advertise it for boats, sheds, barns, etc. Not really houses. The loud is pretty loud - not painful, but not something you'd want to listen to. The medium you could cover up with TV or music or not hear a couple rooms away. Since my interest is mostly in keeping mice away when it's unattended.I cranked it up to loud and left. I'm curious to see if there are any sign of rodents when I get back. I'll update the tread.
They're actually kind of expensive. But it might be something to look for at thrift stores, flea markets, etc., or invest in if you have a particularly bad problem.
Anyone ever heard of this kind of repeller?
