Beavers are right up there with GBH's to me. Both are very smart, and take a little more effort to deter than some other critters. Mine wised up to lead poisoning, then cages, then conibears, then I finally got with esshup, and went to snares because of his advice, and finally got all mine. To me, the biggest issue was knowing what to look for hut wise, and keeping on the lookout for slides and new tree damage.
One hut trail that we dug out, and repacked.
