I have a cedar deck (not sure how old, but likely over 10 years) and there are constantly wasps landing on the wooden parts, I'm guessing chewing it up to make nests, cause you can see streaks of fresh cedar on the old (grey) posts.
I destroyed 4 small nests, the neighbours too care of theirs also. I hung a fake nest on the deck. As far as I can tell they haven't built any new nest on my lot, but obviously there are other nests somewhere not far from here cause the number of wasps chewing up my deck hasn't decreased much.
I hung a wasp trap and that wasn't too successfull. It caught maybe 2 wasps per day. What else can I do to get rid of these guys?
I don't particularly care but when people come over for a barbecue some are pretty sensitive about it, and I have a small kid who will probably get stung one of these days.
Also I sometimes see somewhat larger white wasps, like this:
What are those guys? They looke mean
