Curious as to what comment language others would make on this situation ?
A couple wasp nests near opening inside attic and it appears other townhouse units have the same situation with just a piece of sheet metal over that tiny opening under the soffit.In this case it is facing NW from which winter weather enters.
Bonus shot next of the downspout at front…ha ha.
It may cause of not using water resistant material which is not good thing. Apply the paint which contains the solution like water resistant which help you to prevent water leakage and this type of issue.
