I have an open wood structure shed. They don't build nests but rather bore
holes in the wood, 1 female per hole drilled. They drill straight in for
about 1/2 inch then make a 90 degree turn and continue drilling. They certainly
could with enough years of hole drilling weaken the structure.
There seems to be two kinds, those with a yellow dot on their head and the
others with a totally black head. I have a tennis racket that I keep out
there and periodically I will go out and kill a few. It seems the males hang
around and wait for the females. The males will fight each other and I have
seen action that looks like they mate with the females in the air. Once I
managed to get two with one swat. After swatting many of the ones with the
yellow head and picking them up I have come to the conclusion and I'm quite
certain they do not have a stinger. But watch out for the ones with the total
black head they are capable of stinging and I have been stung with no serious
consequences.
This spring I decided to keep track of how many I kill and to date I have
killed 38 with my tennis racket. I've been doing this now for about three
years and this year I am not seeing nearly as many as in past years. More than
once when I've swatted at one and missed they'll come back and dance around
me, looked me over, but have never been attacked or stung. NEVER. Actually
they seem quite docile. In past years I've killed, by swatting, as many as 20
a day.
But watch out for the little bumblebees that nest in hay and grass. Those
are mean little SOBs and will sting if you just get close.
