Wasps nests can be located either in the ground or in cavities, or in trees, walls or buildings. More commonly wasps will nest in the roof space of a house. Wasps nests pose a particular danger to you, your family, employees or members of the public.

The first workers born to the mated queen start the tasks of expanding the paper nest started by their mated queen and to take care of the young brood.  As new workers are born, they too join in the job of expanding the nest and caring for the rest of the colony.

By summer, the foraging workers are in large enough numbers to become pests when their nests are in close proximity to man.  These workers forage for a variety of foods, depending on the needs of the colony.  In the fall of the year, new reproductive's are produced by the colony, mating begins and the cycle starts again.
It is not uncommon for wasps to be seen, swarming in small numbers around homes and buildings in the fall.  The mating cycle causes wasps to fly around, becoming a nuisance to homeowners who cannot locate a nest to kill; they only see the wasps hovering around their homes and landscaping.
