Yellow jackets are a type of wasp belonging to the family Vespidae. They are known for their distinctive black and yellow coloration and are often mistaken for bees. Yellow jackets are social insects that live in colonies, which can contain thousands of individuals. They build their nests in various locations, including underground, in trees, or in man-made structures. These insects are omnivorous, feeding on a variety of foods, including insects, sugary substances, and human food. While they play a role in controlling pest populations, yellow jackets can become aggressive, especially when their nests are disturbed. Their stings can be painful and may cause allergic reactions in some individuals.
