The iridescent blue mud dauber, Chalybion californicum (Saussure), takes over nests of the black and yellow mud dauber. It provisions its nest mostly with black widow spiders.
I've got mud daubers something TERRIBLE this year and was looking into controlling them.
May accidentally have helped you out, if you import them
Of course you may not trust work done by Aggies <running like hell>
