Wasp nests are made of paper pulp, which is created by the wasps themselves using raw wood and their own saliva. The queen wasp begins the building process by selecting a suitable site for the nest and then searches for sources of wood fiber, such as trees, logs, fences, and even cardboard. Using her strong jaws, the queen scrapes off bits of wood fiber to use. With a mouthful of wood fibers, the queen uses the saliva in her mouth to break down the wood fibers until they form a soft paper pulp. She then flies her mouthful of paper pulp to her chosen building site to begin construction of the nest. The paper pulp mixture used to construct the nest contains a certain amount of wax which helps with waterproofing. The nests can vary in size, shape, and location depending on the species that made them, but they typically resemble honeycombs or an enclosed paper structure.
