You can sometimes buy foam closures or even fabricate metal closures. You can also seal with a quality color matched sealant. In reality, while I understand the concern, I have only seen a couple of instances where bees did build nests in such areas.

My neighbor just had a standing seam metal roof installed today. The gutters have already been re-installed. There is a half/round opening at the end of each standing seam which will allow yellow jackets, bees and other insects to get under the roof. Is there a standard flashing to cover these openings? Or can you fill them with caulk? They were told that the openings had to remain open for ventilation purposes - but my friend is MOST unhappy with that idea as yellow jackets are a real problem here. (The new roof was installed on top of an existing old roof using 2x4's to raise the metal roofing panels).
