What is one of the best indications of a severe roach infestation?

Fecal matter accumulation is one of the best indications of a severe roach infestation because it shows not only the presence of roaches but also suggests that a substantial population is residing in the area. Cockroach feces are often left behind in the locations they frequent, such as kitchens and bathrooms. The quantity and distribution of this fecal matter can indicate the severity of the infestation, as light or sporadic droppings might suggest only a few roaches, while significant accumulation indicates a larger, established population.

Additionally, fecal matter from cockroaches can also pose health risks, as it may contain allergens and pathogens. Observing an abundance of droppings can thus prompt necessary control measures to address the infestation effectively.

In contrast, while curled wings and dead roaches may suggest the presence of cockroaches, they do not necessarily provide a clear indication of the extent of the infestation. Curled wings might indicate that a cockroach has molted or died, but a few dead roaches do not typically correlate with a severe problem. Recognizing fecal matter as a key sign allows for more effective pest management and control strategies to be implemented.
