Wasps
Overview
Wasps are predators and are often visually confused with Hornets and Yellow Jackets. Proper identification by a pest control technician is crucial to ensure proper treatment is administered. Wasp activity is at it's greatest between the months of April and October.
Wasps usually build their nests in the eaves of houses, around corners of windows, etc. These nests are usually made up of grey paper and sometimes referred to as Umbrella-shaped.
By observing wasp activity, infestation locations can be determined and treated accordingly. For example, if wasps are abundant in bushes, it is an indication that the bushes have many insects in them upon which the wasps are feeding, however, it does not indicate a location of infestation. It is important to realize that these wasps are not there because of a nest, and are only traveling to the bushes because there is food present. The abundance of wasps in the bushes will disperse once the insects upon which they are feeding are eliminated.
During the rest of the year, wasps 'overwinter'. This means that the wasps do not build nests, instead they enter structures, such as houses, and nestle deep into the insulation and go into a dormant state. On very sunny days, the walls will begin to warm the inside and the wasps may become active. As they begin crawling around within the walls, some of them may find their way, accidentally, into the living portion of the structure via gaps in the drywall. However, this does not indicate a wasp infestation and does not require treatment.
Biology
All wasps are approximately 3/4" long and 'lanky and awkward-looking' compared to the other stinging, such as Yellow Jackets and Hornets. A number of species of wasps vary drastically in color. The most common wasps will be burnt orange/brown in color, but many also have black or yellow stripes. Wasps also have few or no hairs, and female wasps have a stinger. Please see pictures below of different species of wasps.
