There are two types of wasps: the social wasps and the solitary wasps. The social wasps are the hornets, yellow jackets, and paper wasps. The solitary wasps include a few different species, one being the cicada killers. The main difference between the two types is the social wasps have a larger population. Yellowjackets and hornets are far more dangerous and challenging than paper wasps. Hornets aggressively defend their nests*, while paper wasps are less aggressive and easier to eliminate. Wasp nests vary in shape, size, and location. They can be open or enclosed, under eaves, in the ground, around bushes and trees, around window and door frames, and other exterior structures. They prefer locations that are currently not disturbed. The primary difference between wasps and bees is what they eat. Wasps feed on insects while bees feed on mixtures of pollen and nectar.
