I don’t leave food out. Garbage gets tossed, counters are cleaned. I replaced half the windows in my home and caulked up the rest. I bought a salt gun and have been picking them off but there’s always more.
How do I figure out where these little fuckers are getting in?
If you’ve got screens, check that they’re in the correct position. I had a sliding screen patio door get knocked off the bottom track, and the gap was wide enough for wasps to get through
