I got the neighbours shed next where I have my bird feeders I asked not to put it there when she moved in. As its only 3 inches off the ground the inevitable happens especially after heavy rain. Nice and dry with a food source near by. So I got an empty compost bin where they run through with a Black Cat and a home made trap, both do well to be fare baited with wax blocks (it lasts quite a long time).
