Mud Daubers

There are actually three different types of wasp that fall under the mud daubers name. These wasps earn their name through their nest-building, for which they use mud. There isn’t a lot of commonality in the appearance of mud daubers. The three kinds range in color from dull black to black with bright yellow to metallic blue. One of the things they do have in common is their most recognizable feature, their long, narrow waist. All three are roughly the same size as well, usually about one inch in length.

Like the wide range of appearances, mud dauber nests are also varied. Yellow and black mud dauber nests can be as simple as one cell tucked in a crevice. However, one of these wasps creates much more exposed and elaborate nests: the organ pipe mud dauber. This wasp’s name comes from its panpipe- or organ-shaped nest, which it will often form on the undersides of bridges. Nests created by mud daubers are used by other wasps, including the metallic-blue mud dauber, and bees when vacated by the maker. When possible, though, mud daubers will use the same nest site year after year.

Controlling Mud Daubers

These wasps are predominantly hunters, with spiders being their food of choice. Adults have been known to feed on nectar as well. Like mining bees, mud daubers are solitary wasps. They are not often aggressive but will defend themselves and their nests if threatened. It is rare to be stung by a mud dauber. As a result, control is not always required. However, the nests can be unsightly and it’s always disconcerting to know you have wasps living on your property. This is especially true as it is not uncommon for mud daubers to form their nests within attics. If you think you might have a mud dauber problem, give Advanced Wildlife Control a call!


Mud daubers have actually caused plane crashes! They have been known to nest in the area of the plane called the pitot tube, which, if undiscovered, can cause the plane to malfunction!
