They're actually Carpenter Bees.
Here's a photo:
I found great success shooting them using green 6mm Airsoft BBs and getting them while they hovered near the nests they 'drilled' into our patio. The spring-loaded airsoft guns were powerful enough to knock them down and made it a simple task of killing them using the human foot. Occasionally if you hit one right it would pop or just die on impact but I found this to be rare.
Never had the need to get the Remington 11-87 with my skeet loads
Muahahaha! I save those for spiders.
