I found a small wasp nest this morning that's about 3" in diameter tucked into the railing of my deck stairs. It's unfortunately facing the side of my house, which is about 6 or 7 feet away, so I'd have to spray it at an odd angle to get enough distance between it and me when doing so.
Upon closer look, however, I'm wondering if it's an abandoned nest? It looks like there are a couple holes in places where the sides may have collapsed:
I haven't noticed any wasps entering or leaving it when I watched it closely for a few minutes in the middle of the day. Is it safe to knock it down? Should I get a spray for it regardless to be safe? Thanks!
