Yikes, is right!
OK this doesn’t happen very often, the swarm decided to stay put and start making honey comb. This can be very DANGEROUS, when they start to make honey comb they will start to really defend and protect their new hive. Also this is a BIG hive probably upward of 50,000 bees and remember if you agitate or accidently mess with them they will become nasty and quick. By the way you can’t put nasty on hold or back to what they were before you decided to mess with – always call a Pest Management Professional such as ProBest Pest Management 480-831-9328
