There are differences between a wasp’s and a hornet’s nest. While hornet’s nests can be as large as a basketball or bigger, wasp’s nests as usually 4-8 inches long in a hexagonal or tubular shape, depending on the species. A hornet’s nest holds between 100-700 workers in addition to its queen. Wasps’ nests only house 20-30 insects, with some specific wasps’ nests only having one insect.
