Cylindrical shapes made of mud as a sign of wasp infestation

Scientifically known as Sceliphron, a mud dauber wasp is a group of various wasp species that share the same properties. The name comes from mud, but how is mud involved with a wasp? And why is the title warning about a mud dauber wasp string?

To begin with, let’s look into the wasp’s biology.

What is a Mud Dauber wasp?

Mud dauber wasps are species of insects (wasps) from either the family of Sphecidae or Crabronidae. They build their nests from mud to feed and grow their larvae. Moreover, the larvae spend the winter in the mud dauber nest and undergo complete metamorphosis. Hence, the four stages of mud daubers are egg, larva, pupae (cocoon), and adult.

Three species of mud dauber wasps from various family are:

  • Black and yellow mud daubers,
  • Organ pipe mud daubers, and
  • Metallic-blue mud daubers.

The adults, both males, and females survive on flower nectar. And one more thing not to miss is that only the female mud dauber wasps has a sting at the rear end. So will it string you? Unfortunately, it can.

How do you recognize a Mud Dauber?

These insects are usually dark blue or black. They sometimes contain yellow coloring or a metallic appearance. The adult, both males and females, is about 1 inch long and consists of a long, narrow petiole that connects their thorax and abdomen. They are found in gardens collecting nectar, in moist soil collecting mud balls, and in garage or window sills where they construct shelter.

What do Mud Daubers feed?

The adult mud daubers feed on flower nectar. The diet menu for their larva consists of spiders. Once the female mud dauber nest is ready, the female mud dauber hunts spiders to provision these cells. They provision the cells with crab spiders, orb-weaver spiders, and jumping spiders for developing larvae.

The metallic blue mud daubers diet menu consists of black widow spiders. One notable thing is black widow spiders are dangerous to humans.

Once they find spiders, mud daubers grab and poison the spider. The venom does not kill the spider but paralyzes and preserves it.

The wasps then carry the prey into their mud dauber nest cell. There, they lay one egg on the spider and seal the nest cell with mud caps. Then they repeat these steps with more mud nests.

The wasps are very specific with the spider size. Instead of filing the nest cell with one or two big spiders, they fill the nests with multiple smaller size spiders. The larvae get out of the eggs and feed on these spiders to grow.

What is an organ pipe Mud Dauber?

The name, organ pipe mud dauber, comes from the specific mud nests that these species build. Unlike black and yellow mud daubers, they do not make a series of nests. They create one long cylindrical mud nest cell forming a long pipe organ-like structure. These mud dauber wasps prey on many species of orb weavers as the source of larval diet. They hunt their prey and carry it to the nest for the larvae.

Pipe organ mud dauber usually builds nests of mud on vertical or horizontal faces of walls, overhangs, cliffs, bridges, and shelter caves. All three species repair and reuse their old shelters year over year. Other insects and wasps also use their abandoned mud nests as shelter.

Where does black and yellow Mud dauber live?

Mud dauber wasps do not live in the mud nest as the nests feed and grow the offspring. Black and yellow mud dauber wasps complete their nest, hunt prey, lay eggs on it, and fly away and never return until another season.

What time of the year do you see Mud Daubers?

In temperate regions like the United States, you will find them in spring and summer. However, in tropical areas, mud daubers are active year-round. Mud daubers can produce one or two generations per year.

What are the common areas to build nests?

Mud daubers are not social wasps. These solitary wasps do not live in colonies. However, one may find several female mud daubers using the same locations to build nests.

You may find mud dauber nests in and around your house, garage, and even aircrafts.

Female wasps collect mud balls and carry them to their nest location to complete the mud nest in layers. On the other hand, black-and-yellow mud daubers create cigar-shaped nests of mud attached to crevices, corners, and cracks. But both of them form many adjacent layers of nest cells.

The metallic blue mud daubers do not make a new nest. They use the abandoned nest cells of black and yellow mud daubers and recondition them with water.

Do Mud Daubers sting or bite you?

Like other solitary wasps, mud daubers do not fall into the aggressive category. The purpose of the mud dauber venom is to paralyze their prey. Hence, the probability of biting human beings is not common. However, mud dauber wasps can sting human beings if threatened.

Are Mud Dauber wasps dangerous?

Mud daubers are not invasive. Their diet menu does not include human blood or skin, clothes or household items. So, they do not bring any threat to your property. Neither their nests destroy your walls or anything. However, a bite from the wasp can be a painful experience.

Mud daubers are a few wasps from the larger wasp species groups. However, they are different from the general wasps in many aspects.
