Bugs eating foam insulation (post #196961)

Greetings all, I have an interesting garage built out of 2x4 scraps long ago. I added blue foam insulation to the outside and covered it with some shiplap siding from a local milling.  Two or three years later I now see lots of blue foam dust piles on the inside, but only on the north wall. Would this be carpenter ants? Contractor ants? What beast burrows in blue foam?  I will explore next summer, but as for now from the inside I see no sawdust and the outside is buried in snow. I presume this must have happened during the spring/summer months.  Any ideas?

Here in NW Oh carpenter ants seem to like to nest between the blue foam and wet wood.  They use that route I think because it's easy going.  Eliminate the wet wood (the cause of the wet) and they go away.
