Eastern Carpenter Bee vs Common Eastern Bumble Bee
Big black bee by the deck - carpenter or bumble?
The quick tell
Look at the abdomen. A carpenter bee’s is bare and shiny, like polished black leather. A bumble bee’s is fuzzy from head to tail, usually with yellow banding. If it is hovering territorially around wood - eaves, rails, pergolas - it is a carpenter.

The big bee keeps dive-bombing me - will it sting?
That hovering bouncer by the deck is almost always a male carpenter bee, and males have no stinger at all. The display is pure bluff. Females can sting but essentially never do unless handled.
Are carpenter bees destroying my deck?
They drill nesting tunnels in bare, unpainted wood - cosmetic damage at first, real damage over years of reuse, especially once woodpeckers tear in after the larvae. Painting or sealing wood deters them; they are also valuable native pollinators, so relocation beats extermination.
