I get wasps inside from time to time, but never this time of year when they have active nests. It's usually the overwintering ones and I see them in the house mostly in the early Spring. Killed quite a few in the house over the years and never been stung. They are more aggressive this time of year while nests are active. If you have nests on that side of the house, hit them with some wasp spray. If you kill them, they won't come (in).
