Yellow Jacket Identification

Yellow jackets are medium-sized wasps with bright black and yellow coloring. They are about 0.5 to 0.75 inches long. Unlike bees, yellow jackets have a narrow waist and a smooth, hairless body. Their wings are long and fold down their backs when they rest. The yellow and black bands on their abdomen make them easy to spot.

Yellow jackets live in large colonies that can house thousands of individuals. They build nests in various places, like underground, inside walls, and hollow trees. Their nests are made from chewed wood fibers mixed with saliva, creating a paper-like structure. Yellow jackets are very aggressive, especially when defending their nests. They can sting multiple times, compared to bees, which can only sting once.
