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
