re: Getting rid of beavers, how?

I don't know about your area but beaver huts are rare in my area. More likely to find bank dens. It looks like a 14-24 inch hole in a bank. Blocking one hole is a waste, likely to have 4-12 exits. 330s or snares are easiest. In the spring castor mound sets make them stupid, if they haven't been trapped before.
