Mud Daubers

Actual Size and Characteristics: Mud daubers could describe any number of species, with many different colorations and sizes, but they are typically mostly black, with yellow accents. They have very thin waists, like yellow jackets. Their nests make them easily identifiable, as they are a unique cylindrical shape and made out of mud.


  • Mud daubers are solitary.
  • They are generally non-aggressive, though they will attack if necessary.
  • Stings are rare.
  • Their nests are a unique, pipe-like shape, made out of mud.
  • Mud daubers eat nectar, but they also have a preference for spiders.



Pest Description

Mud Daubers Description

Mud daubers are named for the way they build their nests, creating cylindrical nests out of mud that almost look like pipe organs. Mud daubers are not typically aggressive, but will vigorously defend their nests if disturbed. Both males and females will eat nectar, but they also prefer spiders, stinging a spider to paralyze and preserve the food. They will then carry it back to the nest, stocking a single cell with as many as a dozen spiders. Mud daubers choose specific types of spiders at different times, and are excellent hunters. 

Problems Caused by Mud Daubers

Although they are considered beneficial insects because they pollinate and predate on other harmful insects, mud daubers can still be a serious problem for humans and animals. The stings are rare, but also painful, and people who are allergic to bee, wasp, and hornet stings need to take special precautions to avoid being stung. If you are allergic or sensitive to stings in general, it’s always best to call a professional when a nest of mud daubers is discovered.

Preventing, Controlling, and Eliminating Mud Daubers

Routine inspection of outdoor areas can be vital in preventing a mud dauber infestation. Their nest is very distinct, and will be recognized immediately by a pest control expert. 

If there is an existing nest near a human-inhabited area, do not attempt to remove it. Mud daubers will attack any perceived threat to their hive. Because they can sting repeatedly, they pose much more of a danger than a simple honey bee. Calling a pest control professional is critical, as they have the necessary training to remove the nest safely.
