I live trapped 16 of the beggars last winter, it took the whole winter to
get them. The best trap had a sprung door, although the trap with a flap did
give me three in one morning. Bacon seemed the best bait, often supplemented
by a trail of oatmeal leading into the trap from the entrance to the den.
I kept the traps baited year round and got another four this last autmn.
