Wasp have a slender body with a narrow waist, slender, cylindrical legs, and appear smoothed-skinned and shiny. Yellowjackets, baldfaced hornets, and paper wasps are the most common types of wasps encountered by people.
Yellowjackets, baldfaced hornets, and paper wasps make nests from a papery pulp comprised of chewed-up wood fibers mixed with saliva. Yellowjackets and baldfaced hornets nests consist of a series of rounded combs stacked in tiers.
Yellowjackets commonly build nests below ground, in trees, shrubs, under eaves and inside attics or wall voids. Paper wasps build nests under any horizontal surface and are commonly found on limbs, overhangs, eaves of buildings, beams and supports in attics, garages, barns, sheds and other similar places.
