mud duppers
How do you get rid of mud duppers from building nest on top of your RV air conditioner
Forum Discussion
If mud dobbers are building on TOP of the ac it's generally not a problem but if they move into cracks and crevices they can block normal air flow. Best defense is to screen the area they're getting into. This is quite often inside refrigerator service panel or furnace exhaust vents and these areas are fairly easily screened.
