Mud daubers are slender wasps that construct nests out of mud. They are nuisance pests and not aggressive.
Mud daubers are found throughout North America, from southern Canada to northern Mexico.
Mud daubers build small mud nests in sheltered locations like garages and eaves of buildings.
Warm and wet conditions are most conducive to mud daubers, since they need muddy soil to build their nests.
Mud daubers are not aggressive and rarely sting. They are solitary, not social, wasps, and do not live in colonies. Mud daubers are predators of spiders and other insects, which they paralyze by a sting.
Mud daubers are one-inch long, slender wasps with a narrow, thread-like “waist” between the thorax and abdomen.
