re: Beavers?

Best thing to do is find where they are entering the water along the bank. It's pretty obvious where they've been sliding down the bank. You can use snares or conabear traps. If they have a dam around there you can go knock a hole in the top of it and set a conabear just in the water where the beaver will come to investigate before repairing the hole. As far as the lodge is concerned if its not your structure they are messing with then I'd leave it alone unless you get permission. Sureshot targets are the way to go if you want to have fun removing some debris.
