This entry point – I couldn’t see this opening really well, but was sure something could gain entry. Could it be a bird or a rodent? This opening in the attic is important to annual checks. I would be concerned just looking at it but still needs to be sealed tighter to not allow unwanted guest. At least the door was closed but what if it was open, who would check and who might be able to close or lock it?
My opinion is that this is a perfect opportunity for rodent activity. The minute that mice or rats get into this space opens the chance for bacteria, urine and feces to become part of this home or business. Mice urinate while on the run and feces may be spread throughout the space.
Annual checks is what I’m saying, top on my list.
