There seems to be almost perfectly round roughly 1/2 inch holes in our plywood subfloor. We recently had the home sprayed for dry wood termites but based on everything I researched this doesn’t look like termites. Any ideas?

    Is it not possible that the hole has always been there it was just filled. Movement in the floor has worked the repair loose. Just an idea. Insects are not normal considerate enough to eat our homes and still make it pretty. 🤣

    Carpenter bees make perfectly round holes in wood. Do you have any of them flying around

  • My guess is it's always been there. Carpenter bees leave a much smoother hole. I would check for any other holes that look the same, and if you find any, call you exterminator back.

    Looks like the holes were there and patched which didn't hold.

    It could be carpenter ants. but it looks like the wood just may have been like this

    Did the exterminator drill the holes? I would ask and also have them recheck so you know for sure. Good luck and stay safe!

      I think Cynthia has the right answer. The exterminators have to get to the termites so they drill holes to spray. Because this is a subfloor they just made a quick patch to block the hole. Check with your exterminator.

    Could it be carpenter bees? They make a perfect 1/2" hole.

    Hello there,

    If the missing plaster is over the nail or screw fixings, then it has" popped" Should have been taped first before plastering. Use a spackle or general filler to fill the holes. Hope that helps.
