Many species of these wasps are native insects in North America.
The Paper Wasps derive their name from their nests. They are closely related to yellowjackets, but have smaller colonies, exposed cells in the nest, and are not the annoying scavengers on human foods that yellowjackets are. These wasps are a nuisance when they sting someone who gets too near their hive or when they are foraging for foods in orchards or backyard gardens. Adults feed on sugary liquids, but gather natural foods such as insect larvae to feed to their own offspring. Colonies do not survive the winter, but are started by a single fertilized female which over-wintered in a protected location. The nest is created from chewed bark, dried plant parts, or other cellulose materials, and the cells in which the larvae will grow are formed as the traditional hexagon shape. Once the first adults emerge they become the workers and the original female, or “queen”, settles into laying eggs. All members of the colony are females and all of them can sting.
Paper wasps are very similar to yellowjackets, but they have a thin waist between their abdomen and thorax, unlike the tightly joined abdomen and waist of the yellowjacket. They are large wasps, usually about one inch long, and colors are yellow with black, orange, or reddish brown. Colonies may eventually contain several hundred workers, and usually consist of a single, flat, very wide nest. The adult workers rest on this at night. It is common for these nests to be built under eaves or in attics.
Physical removal is effective if care is taken, particularly by a trained professional from Bugs B Dead
A number of species of wasps in this family are native to North America, with the Black and Yellow Mud Dauber and the Blue Mud Dauber most often nesting on structures.
Mud daubers are solitary wasps that provide a nest and food for their larvae but do not further care for them. The nest is created from blobs of mud gathered by the female and formed into hollow cells, often with many cells arranged next to each other in columns. The female then gathers food, in the form of insect larvae or spiders, stings it to paralyze it, and then places this immobilized prey in the cell. She lays an egg in each cell, seals the cell with mud, and never returns. While the female mud daubers can sting it is a rare occurrence. They do not defend their nests and will sting only when they feel directly threatened. Nests are commonly placed in the eaves or attics of houses, but will often show up in other odd locations where the nest could be placed securely.
The most common mud daubers around structures are the large black and yellow species and the metallic blue species. These are long wasps with very long, thin waists and small abdomens. The black and yellow species may be an inch long, while the blue species is slightly smaller. The antennae are often somewhat curled.
Control can be accomplished by having a trained professional remove the mud nest. Otherwise, these wasps are highly beneficial due to the number of other insects and spiders they capture. Call Bugs B Dead for all your pest control needs.
