Please see the pictures. Single small hole in the drywall. The debris is from one day. Is this a termite exit hole? We live in Sacramento - Central California. I can't find any other signs. The rest of the drywall is clean.
We had some bathroom work done about 5 months ago, which included opening an exterior wall. There was some water damage to an exterior wall, but no obvious termite damage. The bathroom door is about 4 feet away. This is an interior hallway wall.
