Mouseblocker electronic repeler?

This works great for Pigeons and small birds.

Have an open storage shed and the pigeons and small birds would fly in there and crap on things parked in there.

Put a Radio in there and I am playing Rock and Roll in there 24/7 now. Not one bird comes in, and the vehicles are staying clean.

Added bonus I get to hear rock and roll when walking up to the back shed.

Win, Win . .

May help to keep mice at bay too. Have not seen any mouse nests built up in that shed either.

I use bait packs to keep any mouse popluation down around the main shop and the paint shop too.
