Help With Identification

[matto]

Inspected a home with the siding removed, the foam board has these holes in it. It is cooler here in Wisconsin and did not see any insect activity. What type of insects "eat" foam board? I am not even sure if this is from insects any help or direction would be appreciated. Bugs are not my strong suit.

Thanks,

Matt

I've seen similarly chewed up foam sheathing in areas of termite damage. I assume that they don't digest the foam, but they can tunnel through it.

Foam isn't much match for any pest that wants to see what's on the other side, especially if it's dinner. I see brickmold on the left, my guess would be carpenter ants.

That would be my guess as well. Remember, the carpenter ant only excavates for a place to live, not for food. It does not eat the wood, it only lives in it. You should remember what the larger galleys look like in the foam as they look just the same in wood.

Carpenter ants love nesting in that stuff.

I agree. Ants.
