Habitat destruction at this point would equal total yard destruction...I keep finding new holes. Once the ground is covered with snow I won't be able to find the holes. I hate to do it but may have to go the poison route, if they will take it. So far they haven't touched it. This time I will try pre-baiting though. These are apparently very smart little destructive creatures. I may try the tin cat traps too.
Did I mention I also have a whole herd of rabbits? I fully expect to have a completely naked yard in the spring
