The queens are fertilized in the fall and hibernate anywhere they want in the winter. The queens start to get active when the weather starts to warm and the cycles starts all over again. The rest of the nest dies with the colder weather. I have never had a customer complain of hundreds of yellowjackets this time of year. Sometimes they scream about a couple that come out of hibernation with this crazy weather. They should be pretty lethargic, just suck them up with a vacum. Will kill for plugs!
Yellow jackets also hibernate, when we open telephone splice cases on the pole they will be in there, moving at super slow speed. With the warm weather we have been having it wakes them up, once the temp starts to dip the will go back into hibernation mode. I hate wasps, bees yellow jackets they always seem to get me
