We have six hives set up in what seemed to be a perfect place behind our garage - wind protected, full sun, with southern exposure. Unfortunately the barn swallows (dozens of them) have returned as they do every year, and set up camp in the eves. They seem to be eating our bees constantly. From what I understand these little avian insectivores can eat twice their weight a day and feed their young up to 400 times a day!
We are new to beekeeping but have been doing math for a while. I'm figuring that this might not bode well for our colonies. I'm not thrilled about the thought of moving the hives but I'm less thrilled with losing the colonies.
Are my fears well founded, or should I just enjoy watching this natural wonder? Does anyone have any experience with this kind of situation?
