Mike, I think that you heard so many answers, mud daubers are cool, they can be nuisance, but when I see them, I don't bother them at all. I don't even think that they bug humans, not like our other friendly bug gers, like the yellowjacket, hornet and wasps, now they are critters I don't want around, even if they eat bad bugs too, they eat our good bugs, like the bees, hee, haw. Ignore the mud duabers, they just want to daub mud. Beautiful day, beautiful life, beautiful. Cindi
