i have a side porch and i think it has cedar slats all the way around under the roof, i found some bees making a few holes that i filled in with caulk but now i found about 8 more holes in a different place which i cant get to fill in as a permanant mesh screen is in the way
i spray raid on all that stuff thru the screen if i see one of *******s and ammonia at the hole but they keep at it
