1 The primary cause of COPD is tobacco smoke (through tobacco use or second-hand smoke).  The disease now affects men and women almost equally, due in part to increased tobacco use among women in high-income countries.
Swarming is the process by which a new honey bee colony is formed when the queen bee leaves the colony with a large group of worker bees. In the prime swarm, about 60% of the worker bees leave the original hive location with the old queen. This swarm can contain thousands to tens of thousands of bees.
Also, some honey bee foragers spend the night away from the hive in the summer, so there is likely to be a cluster of bees forming around the entrance after the bees and combs have been removed. That small number of bees can be vacuumed up or eliminated with an aerosol spray labeled for use on wasps and bees outside the home.
