>What are the drawbacks to working with bees at night? I hear everybody say it's bad but not why. Any ideas?

They cling and crawl. ALL the bees are home, and the field bees are not in a good mood at night. They fly at the light. A red light would help a lot, I would guess. I have, on occasion opened them at night when I had to find a queen to ship etc. when it was the only time I could. Some hives respond better than others. None of them respond well.
