Signs of a Roach Infestation
The first sign of an infestation is that you see a single roach. Many times the first roach seen came out of the walls due to overcrowding in the colony. That means you have a lot of them.
You can also look for fecal matter near food and water sources. A good place to look is under sinks. The fecal matter looks like black pepper. Caution, don’t eat the black pepper you find.
