How Do You Control Mud Dauber Wasps?
Several species of mud dauber wasps thrive across the United States. They build nests out of mud that are often quite large and elaborate. Mud daubers commonly gather mud at the edge of rivers, ponds and lakes. They will often construct their nests on the side of houses, in brick mortar, window frames and door frames. They are considered beneficial because they readily consume harmful insects. However, mud daubers can sting when people come close to their nest, so it’s in your best interest to control them. Spray mud dauber nests off the side of houses and buildings when they are quite small, using a hose and water. Stand back at least 10 feet. It is best to hose a nest off a house during the night when mud daubers are the least active. Unfortunately, the mud dauber will often return to the same location over and over again to rebuild. Purchase an insecticide wasp killer that contains cypermethrin. Mix in a handheld sprayer according to the directions on the label. Cypermethrin is sold
