Hi all, Someone called me last week to come out and remove a feral beehive from the storage bin of his camper. When I arrived we found VERY few bees - and larvae was squirming out of their cells, falling to the floor of the storage compartment (alive). The few remaining bees looked like freshly emerged nurse bees and plenty of brood remaining. Fresh eggs were all turning shades of gray and drying up. A few wax worms were working their way through one of the combs. It looked as if 100% of the bees absconded in the last day or two - leaving plenty of honey behind (not robbed as there were no torn cells). The homeowner said he had backed his diesel truck up to the camper a couple days before. He left the engine running and returned to notice all kinds of bees flying 20-30 minutes later. It looks as though the exhaust flooded the hive since the tailpipe was probably a foot away from the bee entrance. Was it the exhaust or wax moths or ?? which drove ALL the bees away? If exhaust works, perhaps this would be a good method to force bees out of hard-to-reach cavities - as long as it doesn't damage them in the process (?).
