What is a common sign of a cockroach infestation?

Fecal spotting or smears is a distinctive sign of a cockroach infestation because cockroaches produce droppings that appear as small, dark specks. These droppings can often be found in areas where roaches are active, such as kitchens, bathrooms, and other hidden places. The presence of these droppings can indicate not only the presence of roaches but also the severity of the infestation, as a higher number of droppings suggests a larger population of roaches in the area.

Other signs, such as noise at night, visible nests, and strange odors, can also be indicators of a cockroach problem; however, fecal spots are typically more commonly observed and provide clearer evidence of their activity. By recognizing these droppings, it becomes easier to identify an infestation and take appropriate action to address it.
