Can anyone help me identify this?
I'm hoping that others have run across this while cleaning and can help me to identify it.
It is a kind of web embedded with what looks like wood dust particles. It's located along the wood frame to my brick fireplace. I can wipe it away, no problem. In fact I've done that before, but it eventually shows up again.
But what is causing it? I don't see any insects in or around it. Is it a sign of termites or wood ants or what?
