Either at the first frost or after a day or two's solid rain the mice invade this wooden house.
We tried humane traps (empty every three hours? From the loft? I don't think so, and if you don't they starve to death..)
Cats in my experience like to torment mice and we might have a cat and a mouse running around at 3 am.
We tried a sonar plug in 'deterrent' - I think this may have reduced the numbers and only the hard-of-hearing mice come in now but..
we've resorted to the old fashioned, nasty but (mostly) quick, mouse traps.
It's a cruel world.
They only want in out of the rain.
