Stop in for a cup of coffee

I've caught over 18 of them in the back garage since middle of summer...

They go in waves... I catch a few for a while, then it's quiet for a few weeks or so....

Then the traps start getting set off or catching one or two again... I have to set another round of traps back there again as I haven't for a month now... Been focusing on the inside...
Ever see the ones people make where the mice walk out on a dowel and then get flipped into the bucket of water ?
