If you can tolerate the presence of wasps or hornets, remember that the nest of the European hornet and most wasps are annual. All inhabitants should be dead or quite dorman during the winter months. You can wait until the late fall and seal all nest openings. At this time the colder temperatures should have killed all the nest inhabitants with the exception of a few overwintering queens.

There are some traps, designed primarily for yellowjackets that are labeled to control wasps. See the Tool Shed for Biting Insect Traps
