How do you get rid of mud duppers from building nest on top of your RV air conditioner

Don't know anything about the flea collar idea except that you'd have to replace them every few weeks, so it's back up the ladder. I would be more inclined to remove the shroud and come up with some screen to cover those areas. For some reason, the mud daubers around us love the WH, refrig and heater outlets but have never bothered our A/C. Maybe being under cover 24/7 discourages them from heading up there. DH got our screens put on last night, so we're not going to have to worry about those nasty things.
