Dirt daubers can be considered beneficial insects since they reduce the number of spiders that most homeowners do not want in or around their home. Mud daubers are more of a nuisance when they use our homes as the location for their nests. If a family member is allergic to wasps, then ridding your home of dirt daubers is important. Also, abandoned dirt dauber larvae and spider prey from old nests are attractive to carpet beetles and other insects that can invade your home.
