I live in a condo (end unit townhouse). There is a slanted wood trim
near the roof on the side of the building. There is a gap behind the
wood trim and wasps (yellowjackets) have been flying into the gap behind
the wood trim and building nests there. Although I wasn't aware of
this at first, my impression is that they have been nesting there every
year. I've been here almost 4 years.

If they haven't gotten inside the building or bothered anyone, are they
best left alone, or does leaving them alone typically lead to them
causing damage?

Seems to me the only permanent solution would involve screening off the
gap, but the wasps would need to be exterminated first, and one would
have to be very certain they are all dead before screening off the gap.
Should I insist this be done, or are they best simply left alone?

Thanks,

Jay

Wait until the come home to roost. Then dowse the crack with a goodly
portion of hornet/wasp spray AFTER sunset. That'll kill what's in the
nest and discourage others. You may have to repeat every season. I've
had good luck with this approach.

when you are convinced they're gone, caulk.
