If you notice tube-shaped nests built of mud on the side of your house, you likely have an infestation of mud dauber wasps. These wasps rarely sting. They can even control your spider population, as spiders are their main prey. Unfortunately, the mud tubes may look unsightly. Mud daubers often return to re-build their nests after you get rid of them unless you take the proper steps to prevent this.
Things You'll Need
Putty knife
Resmethrin/pyrethrin insecticide
Fly swatter
Trash bag
Hose end sprayer
Garden hose
Cypermethrin insecticide
Remove existing mud dauber habitats. Scrape the mud tube nests off your home or other surfaces with a putty knife.
Spray any wasps you encounter during nest removal with an insecticide that contains resmethrin or pyrethrins. Or you may simply swat the wasps with a fly swatter.
Dispose of the nests far away from your home to prevent secondary infestations. If you live near the woods, you may dispose of the nests there. If not, seal the nests in a trash bag and bring it to the dump.
Attach a hose end sprayer to your garden hose. Fill the sprayer's tank with a Cypermethrin-based insecticide.
Adjust the hose end sprayer so that it applies 1 oz. of insecticide per 1 gallon of water.
Spray the entire surface where the nests were located. Work your way around the building, spraying all the other walls. This prevents the mud daubers from simply returning and building nests elsewhere.
Apply Cypermethrin insecticide once per month during the spring and early summer to keep the mud daubers from coming back. Apply every two to three months during the rest of the year.
Tips & Warnings
Keep children and pets indoors while applying pesticides.
