Mud daubers or wasps are altogether different, most resemble long, slender wasps about 2 ½ cm in length. They are solitary (lone) wasps, so instead of big colonial nests, they build single-family nests. They also use a different construction materials, instead of wood, they mix their saliva with soil to make mud, exactly the same as mason bees. They then build their nest on the side of a building, attics, soffits or in a hole in the ground. Their nests can be multiple shapes – tubular, round, or rectangular and typically measures 5 cm in diameter. One species of mud dauber actually never builds its own nest rather it steals other mud daubers nests. If a mud daubers nest is attacked, they prefer to move on and build a new nest.
