I have a guy that has a tree in his backyard. About 40' up, he has a hive he wants to get rid of asap. He doesn't want his kids stung, and he's afraid of liabilities. He doesn't seem to be the type to reason with. I explained that if I just seal it up (provided there are no other cracks in the tree) that the hive will basically rot out and turn his tree into one big old stale beer. He kind of thought that was a little funny, but then thought his wife might not share his sense of humor.
I may be able to keep it from being a total loss. I may talk him into a 1 or 2 week trapout. My thoughts are that I get the majority of the workers in the first 3 days. Then at say day 7, I shove a bunch of blocks of dry ice in the hole and seal up the entrance. 2 days later, I reopen it to allow the decoy hive to rob it. Day 11, I empty 3 cans of spray foam into the cavity (hopefully to make it smaller and less likely to have a return and then physically block the hole with screen and tar.
Any thoughts? Suggestions. The idea is that the dry ice kills off any remaining guards as well as the queen - last thing I want is that the decoy wants to move back in. My best case scenario is to have a queen cell that wants to hatch 2 days after I hang the trapout up there. Killing off the old queen and waiting 2 days allows the scent to dissapate.
Last item: I only do a few extractions per year. I know what to charge there because of the construction - and I have a set amount of hours it normally takes. In this case, it's a bunch of little out of the way trips.
