Re: Do any other bees except for honey bees swarm?
Ants swarm, termites swarm. Probably any insect w/ a social structure like ants, termites, and honeybees swarm. Bumblebees probably don't. Their lifestyle is quite different.
All social insects maintain a colony in exposed comb, or protected comb, or in a cavity of some sort often called a hive or nest. The wording used by the person doing removals was to distinguish between honeybees which they apparently will deal with, and nonhoneybees which most people don't think about as not being honeybees. Any flying insect living in the wall of their house. He must not be an exterminator and wants people to know.
