Doing some light replacements in the soffits and painting/sealing while weather is cooler, noticed this yesterday, can’t see it from the ground, few nests in this “cubby” didn’t look occupied, and this doesn’t go into the attic, just doesn’t completely close off for whatever reason.

I can continue to spray these, or is there something I can do/add to keep things from hanging out in this spot? Flashing all the way to the shingles or is that a thing? 🤷🏻‍♂️
