I hate beavers.

Their is a trapper in our area too that'll come out and get rid of them for you for free. They can be ornery buggers damming up creeks and whatever but I feel it's best not to kill them as every creature plays it's part in nature. Just let the local trapper re-locate them. JMO

p.s. Look in your local ph book for the game and wildlife # and call them. Should be a listing but if there isn't you can probably google.
