Wasp problems

[CountryGardener]

Hi guys! :)

I've got a mud dauber wasp trying to build a nest in my workshop/shed. Whenever I latch its doors open to let paint fumes, etc, out, within about 3 min., in comes Mr. Mud Dauber to daub his mud. I don't want do kill the fella, since he makes good spider control/pollination, but I can't have him building his nest in my shed. Do any of you know of wasp repellents?

Thanks in advance! :D

Mud daubers continue to use the same area for their nests. To eliminate the problem, adults can be killed with insecticide and nests scraped down.
