These pests tend to be solitary wasps, but they can infest your yard in large numbers, especially if they find a favorable environment for nest building. Female mud daubers lay hundreds of eggs in their mud nests, which hatch into larvae that feed on spiders.
These wasps are attracted to sheltered areas like attics, eaves, and sheds, where they can build their nests undisturbed. Over time, the nests can accumulate, potentially blocking vents, water flow, and other critical systems.
