Bees under the floorboards...
Seems bees built their hive underneath my floorboards... When I crouch and put my ear to the floor, I hear their faint buzzing, and when I step from the mudroom to the deck, I see this...
I do hope they'll move on this fall. They get riled up when I step outside to fire up the grill, but I've not been stung. The smoke from my veggie kabobs calms them...
