Identifying The Smoky Brown Cockroach
The Smoky Brown Cockroach, Periplaneta fuliginosa, is a species that is relatively easy to identify.
Distinctive features include:
- A uniform, mahogany-brown coloration without any distinctive patterns.
- An average length of about 1.5 inches (38 mm).
- Long wings that extend beyond their body, make them capable fliers.

Lifecycle And Habits Of Smoky Brown Cockroaches
Understanding the lifecycle of these cockroaches helps in preventing their growth and controlling their population.
The lifecycle stages include:
- Egg: Females deposit egg cases, each containing numerous eggs.
- Nymph: Once hatched, the nymphs undergo multiple molts before becoming adults.
- Adult: Adults possess developed wings and are active fliers, especially at night.
Their behavior is characterized by nocturnal activity and they are attracted to light.
These insects typically feed on a wide range of organic matter, including decaying plant material and waste.
