Yellowjackets belong to the Wasp family and they are especially aggressive. They are typically seen during your outdoor barbeques, and often they seem to attack for almost no reason at all. Their diet consists of sugars from nectars and fruit, and carbohydrates from meat and other insects.
They are easily identified by their distinctive bright yellow and black coloration, their aggressive behavior, and their fast and precise flying abilities. Unlike Honey Bees that can only sting you once, a single Yellowjacket can sting and bite a person or animal multiple times.
Overwintering queens will emerge in the late spring in search of new nesting locations. She will develop an initial 30 to 50 brood cells for 18 to 20 days, before taking on the sole purpose of egg laying. A full-size colony will reach up to 5,000 workers. As the colony begins to die off in the fall, newly developed queens will find a safe place to overwinter to start the process again next spring.
