Mud Daubers in Dayton, OH

As their name suggests, mud daubers build mud nests and live alone rather than in colonies. They are found throughout the United States and include a wide variety of species. In addition to their unique nests, the thin waist that separates the abdomen and thorax is a key trait that sets them apart from other wasps. Mud daubers are usually calm and will only sting in defense of their nest.

Mud Dauber Habitat

Mud dauber nests are built by females and consist of narrow, cylindrical mud tubes arranged side by side. These nests are most often found in sheltered, shaded locations such as sheds, barns, porch ceilings, or beneath roof overhangs. The female supplies each chamber with spiders that have been paralyzed for the developing larvae. An egg is laid inside the chamber before it is sealed shut. As the larva grows, it feeds on the stored spiders until it pupates and emerges as an adult. Empty nests with round holes indicate past activity rather than an active infestation.

Mud Dauber Behaviors, Threats, or Dangers

Mud daubers are generally non-aggressive and rarely sting, even when disturbed. They play a useful role in the ecosystem by reducing spider populations. Their presence is often more of an annoyance than a true threat. Problems arise when they choose to nest in high-traffic areas of a home. In these cases, nest removal should always be performed by a professional wasp control company to avoid injury.
