I also had an opposum problem. My hives are on my deck and on stands up off the deck floor. The two suggestions I have tried are: 1. Put chicken wire on the ground around the hives. Apparently the offending animal doesn't like the feel of the wire around their leg when the walk on it. (I tried this on my deck but I had additional visits. I may be because of the flatness of the deck surface.) 2. Put baited mouse traps out and snap their noses or paws. I wired the traps (six total around the 3 hives) to the chicken wire on the deck floor and baited with a dab of peanutbutter and a tiny slice of apple. The first night an opposum set off one of the traps. I heard the trap go and flipped on the light to see the opposum skulking away. At this point the apple and peanutbutter are long gone but I leave the traps set. The rain has set off a few so I reset them. I seems to be working for the moment. My cranky hive is very much less cranky, though still the hive with the most personality and I haven't seen any evidence of visits. Hope this helps. Jim Moore [log in to unmask]
