I've got a lovely, wooded area along a creek for a bee yard, but it comes with loads of possums. They get into my sheds and storage areas, knocking over stacks of hive bodies, scattering piles of inner covers, tearing up nucs with live bees and generally making a mess of things. I've trapped some in those wire "have-a-heart" type traps and relocated them, thinking I was doing them a favor. I've killed some and gave the carcass to a buddy who skins them (and gets about 50 cents a pelt). He said he appreciates my kindness but he feels it's hardly worth the 50 cents anymore.
My next thought is to figure out the open season and simply hunt them with a shotgun and flashlight -- everything legal. But that's more time and not very efficient.
I used carpet strips on the landing boards of the nucs but it doesn't seem to help. Anyone have a more permanent solution?
