Termites love to munch on scrap pieces of wood. If you leave the wood, they will come. This is exactly why termites reports warn about "cellulose debris".
Notice the termite fecal matter that looks like dirt. No that's not dirt. It's termite wasteproduct.
Normally, humans only see the "evidence of termite infestation" and rarely see the termites themselves. That's because termites don't like sun and dryness. They like dark and damp. This piece of scrap wood was inverted and soaked with water. When I flipped the board over, I caught the little munchers in action.
