I dont know why, but I am deathly afraid of wasps and mud daubers. only been stung a couple of times, but I get the heck outta there if I see any. They like to buil nests in my 12 x 14 parts shed, it got better after I painted the entire inside of the shed white (it's wood) It took a lot of paint, but it was so much brighter, and it reduced the wasps. I also had an oil bath air cleaner sittin on roof of my 54 **** car for a couple years, took it off the other day, nests built all over inside where the carb throat would have been !!
