Last summer, we found three dead queen wasps and many more live ones, which is unusual, because we have never seen them in the past summers. They were about an inch long, and it looks like they have two stingers. One "stinger" is about a centimeter long. Does anyone else have problems with these wasps? If they come back again this summer, will they affect my hive at all? I would post pictures, but not enough posts yet. :'(
