There are several varieties or species of wasps in North America, including the yellow jacket, hornet and paper wasp. Colours range from black to combinations of black with yellow, white or brown markings. The slim, winged body measures 10 to 19 mm (1/2″ to 3/4″). All wasp species have chewing mouth parts and the females possess a stinger.
Colonies consist of queens, workers and males. Wasp nests can be found in and around buildings on the upper casing of windows, verandas, gazebos, under eaves, ceilings, attics or in trees and shrubs. Several varieties of wasps build nests underground. They are also found within building wall voids.
Wasps are attracted to sweet smells like flowers, fruit, rotting fruit, rotting vegetables, juices, ice cream, soft drinks, beer, deodorant, cologne and perfume.
The queen lays all the eggs. Most eggs develop into sterile workers. Late in the season, the queen produces eggs which develop into queens that will establish new nests the following spring. An average of 1,000 to 3,000 eggs are laid per nest which hatch and develop on a daily basis. Only the new queens survive the winter while the rest of the colony dies off when weather becomes cold. The queen survives winters under loose bark or in crevices and lays eggs in the spring to start a new colony.
Whenever possible try to eliminate fallen fruit and refuse which will attract wasps. Sealing holes and other potential sites may help prevent nesting.
Once a nest is established do not seal the hole until after treating and make sure there is no more activity. If you seal the hole the wasps can develop nests in the wall voids.
Preparation Steps for Wasps Treatment
- Your AR Pest Control technician will inject a pesticide directly in the nest to kill all stages of the insects present in the nest. If possible, your technician will remove the nest. Wasps that were not in the nest at the time of the treatment will return and will re-enter the nest and die. If the nest has been removed the late arriving wasps will typically leave the area.
- Generally, there is no need to vacate the premises however, it is advisable to avoid the immediate vicinity of the nest for at least 24 hours.
