Many of them have beem seen on the outside of our doors and windows at night time. How long before they die out, and can they renest? This happend late August and it is not mid September here in Pittsburgh Pennsylvania

If a nest is destroyed when all of the insects aren't in the nest, some of the returning yellowjackets circle around in a disoriented way trying to regroup.
