We seem to have an abundance of the skinny little wasps that look so intimidating but pose a real threat only to spiders, which they sting and place inside the nest as food for the young. Dirt daubers don't bother me, and won't you, either, unless you try to squeeze one in your hand. But their nests do make a mess on our front porch and under the carport. Yesterday was clean-the-front-porch day, so I spent a lot of time washing away their mud huts. Sorry guys.
