Found tons of little black beetles in the hive we extracted today. They'd pop out of one cell and quickly go back into another. Which for some reason was very unnerving to watch. Think it had something to do with how shiny and round they are and how they fit into the cells. Maybe it was the speed at which they crawled idk but anyways I have questions.
What are they?
What do they do?
Why don't the bees kick them out?
Can they infect my other hives and if so how can I prevent that?
Assuming they're pests, how do I get rid of them?
