What do termite pinholes look like?

Termite pinholes are tiny, perfectly round holes, typically less than 1/8 inch (3mm) in diameter, resembling a small nail or pinprick. They have clean, smooth edges and are often found on wood surfaces like ceilings, walls, or doorframes. These are exit holes created by subterranean termite swarmers when they leave the colony to reproduce, and may appear dark or wood-colored.
