Charles Ray, an entomologist with the Alabama Cooperative Extension System (ACES), says Yellow Jackets are creating "super nests" that are three to four times the size of regular wasp nests! A regular nest is equivalent to the size of a volleyball and houses about 4,000 to 5,000 worker wasps. The "super nests" are housing up to 15,000 worker wasps!
