|Those yellowjackets are attempting to build nests within the hollow parts of the railing. They are attracted because of the heat generated by the black metal and there are probably small holes in the joints or where the railing meets the porch supports. Carefully examine the entire railing for small holes (fill them with caulking if you find them). You can't keep yellowjackets from exploring, but you can keep them from nesting near your porch. Hope this helps!
