Some notes: The deck is built over the carport. In the carport, plywood ceiling with no sign or smell of bees. The deck is only open to the outside on 1 side (pictured), and is completly covered including skylights. The floor is OSB covered with astroturf. (yes, I said it correctly, Garage celing is plywood...Deck floor is OSB!!) The pile of dead bees on the ground is from the homeowner spraying wasp spray at the skylights... sniff...sniff. RIP Girls. The entire area around ALL sides of this property is swarming with thousands of bees. The porch is even worse.
My take on things. Large, established colony under the flooring of the porch, running between joists. Bees are coming out of the crack and flying toward the sun thus getting trapped by the skylights. Other possibilities, I could have 3 seperate colonies. 1 at skylight, and 2 in the deck floor. Notice they are coming out of the crack in 2 places about 5' apart. The only way to know is to rip up part of the astroturf and look for nail heads. If the joists are parallel to the house, 1 colony. If not probably 2 colonies. Also they could be in the wall, not the floor. What does everyone think? I will post pictures through completion of this removal.
The last picture is a house across the street. Bet I know where these came from!
