I have wasps that seem to be nesting near my home entrance. They look like bald faced hornets (black & white, short thin waist, ~1" long) from the pictures I've seen, but I can't find a nest. The activity in the daytime (maybe 2 dozen wasps) leads me to think the nest is under our porch (raised 15 inches off the ground). But I can find no nest. I think I've seen a couple abdomens sticking out of carpenter bee holes, though! I've never heard of any kind of wasp inhabiting carpenter bee nests, but one thing's for sure - I haven't seen any carpenter bees in the last few weeks, and I usually have a lot of them. Is this just a coincidence and I haven't spotted the nest?
Any ideas?
Thanks,
Jesse G.
