What is often a telltale indicator of a cockroach problem?

Fecal pellets are a key indicator of a cockroach problem because they are a direct sign of their presence and activity. These droppings can often be found in areas where cockroaches feed, hide, or travel. The size and shape of cockroach feces can vary depending on the species, but they generally resemble small brown or black specks, often compared to ground coffee or pepper.

The presence of these fecal pellets serves as both a warning sign to property owners and a clue in the pest control process, indicating where to focus efforts for elimination. Noticing these droppings can prompt further inspection and potentially lead to identifying areas of infestation, helping to initiate appropriate measures to address the problem effectively.
