To Discourage Evil At Your Door

" Paint your door or front porch ceiling “haint” blue (a light sky blue or some say Carolina blue) to discourage evil at your door. The color is also used to trick wasps and spiders from nesting on ceilings. This originated through African-Gullah folk traditions and can be found through the southeastern mountain areas as well as southern coasts." From Granny Buck's Dibs and Dabs
