You also might try to find the source of mud and eliminate it. If you water
your landscaping regularly, the daubers look for bare or muddy spots to get
their mud from. Mulching any bare spots may deprive them of building material.

Certain types of these daubers build their nest in small existing cavities
rather than on the surface of walls and such. I've had lots of problems with
them building their nests in air hoses and other various tools. Once had a
nest in my table saw motor that kept it from operating.
