Mud wasps are slender insects with a narrow waist and long legs. They vary in color from black to brown, and some species have yellow markings. Mud wasps typically have a smooth, shiny appearance and build their nests from mud, giving them their name.
Mud daubers do not typically live with spiders, but they are known to use spiders as a food source. These solitary wasps build their nests from mud and often stock them with paralyzed spiders, which serve as provisions for their larvae. While they may share habitats, they do not form social colonies like some other insects.
Mud daubers typically build their nests outdoors, often in sheltered areas like eaves, barns, or sheds. However, they can sometimes construct nests inside houses, especially in garages or attics where there are suitable materials and protection from the elements. These nests are usually not harmful, as mud daubers are solitary wasps and do not pose a threat to humans. They primarily feed on insects, which they use as food for their larvae.
