Concerned about Bumble Bees. A couple summers ago I noticed some bumbles nesting in a wood plank apart of the deck here. I noticed this spring there were much bigger choppy holes next to their near perfect holes. Only one is headless (middle bumble). Does anyone have insight for what happened here?
