This group of wasps gets its common name from the fact that they construct their nest of mud. Mud daubers are found throughout the United States.
HabitsMud daubers are solitary wasps. They are not social and do not live in colonies as do other bees and wasps. Mud daubers provision spiders for their larvae by paralyzing them with their venom and bringing them into their nests.
HabitatFemale mud daubers construct nests of mud. Many short mud tubes, usually about 1” long, are constructed side by side. They usually build their nests in a sheltered site, such as under eaves, porch ceilings, in garages and sheds left open, in barns and attics, etc. Nests typically exhibit round holes in them as the wasps emerge. This means the nest is probably old and inactive after springtime.
ThreatsMud daubers do not defend their nests and only rarely sting. They are typically considered nuisance pests, and are actually beneficial as they help control spiders.
Prevention:Although mud daubers are not typically dangerous, their nests should be removed by Stop Bugging Me Pest Control if found on your property, as their abandoned nests are often adopted by other more dangerous wasp species. Stop Bugging Me Pest Control offers wasp and bee extermination services throughout the entire service area including Seattle, Bellevue, Everett, Tacoma, Kirkland, Issaquah, Lynnwood and the entire Puget Sound region.
