Mud Daubers in Your Area
Mud daubers are solitary wasps that are known for building distinctive nests out of mud tubes. Multiple 1″ tubes are placed side by side, which are used for shelter and laying eggs. Outside of their unique nests, mud daubers can easily be identified by the ultra-thin thread-like waist between their abdomen and thorax. Mud daubers primarily feed on nectar, insects, and spiders. Though these wasps have an unusual and somewhat frightening appearance, they are not aggressive and rarely sting unless threatened.
Mud Dauber Habitat
Female mud daubers are responsible for building the distinctive cylindrical nests that this species is known for. These nests are made using short mud tubes placed next to one another, and they are typically placed in sheltered areas like porch ceilings, sheds, or barns. Once the nest is constructed, the female mud dauber will paralyze and collect spiders using her stinger. She will then place the spider inside of a mud chamber, deposit an egg on top, and then seal the tube so the larva has a safe place to feed and grow. If a mud dauber nest has small, round holes dotted along the outside, it could mean that the wasps have already emerged and the nest is no longer in use.
Mud Dauber Behaviors, Threats, or Dangers
Though mud daubers look frightening, they do not defend their nests and are not usually aggressive toward humans. Instead, these wasps can be beneficial to the environment by helping with pollination and controlling spider or insect populations. That said, they can still be a nuisance if they decide to enter your living space. If you identify the signs of a mud dauber infestation in or around your home, it is important to call a professional wasp control company, to handle these pests safely.
