I had a friend use one of those buckets with a flip lid on top and a ramp up to the top where he placed food along to draw the mice out, up the ramp and then onto the flip lid and drop into the bucket. I was surprised that it actually worked. Some people put water in the bucket so the mice eventually drown. Or, put nothing in there, let them fall in and then haul them out somewhere so they don't come back. Only took a few days to clear his house and immediate property around his suburban house.
