Controlling mud daubers

Small tube-like nests made out of mud indicate a mud dauber has moved in. This species of wasp likes to build its nest in areas such as under decks and on garage walls. The insect is rather docile as far as wasps go, but if you're uncomfortable with their nests, just knock them down.
