Cricket poo often is confused by a lay person as termite damage or frass. Cricket feces is black odd shaped star looking almost ripped edges. Termite feces is used with tunnel making or with Drywood termites hard shell ribbed edges. Subterranean termites mix the dirt and poo together in the building of the termite tubes and/or tunnels.
The Art of Pest Management is with the knowledge and what and how pest occur, that by the way is why you pay me. Because I KNOW. I continually run into people that say the previous person said this and that is wrong. They might say its bed bug and I go and its springtails or even ticks. That’s another treatment protocol and generally a lot less money.
