Question: I have wasps — I think they”re yellow jackets and they make hives that look kind of like a beehive. From what I”ve read, the queen stays alive during the winter but is the only wasp in the nest. I”d like to knock the nests down before they start to multiply for the season. Would it be fairly safe to knock out the nests at this time of year?

ANSWER   The nests are empty this time of year, and they will not be used again–so you can remove them. Wasp control is best done in the spring when queens are building new nests.
