Teardrops n Tiny Travel Trailers

inside the wall at the front right of the trailer. this shows the depth of my walls, particle board to styrofoam insulation. (lucky for me the yellow jackets had all been killed by then, even in the walls as there were other nests inside and I sprayed inside and all around under the eves, then let it set for a day or two. after this I caulked up all the openings around the edges.
