How do we prevent/treat for the smokybrown cockroach?

  • First and foremost, check the attic or crawlspace
  • Secondly, apply a granular insect bait in the attic or crawlspace
  • Thirdly, look for cracks and gaps where they can be getting into the structure
  • Fourth, gain control by sealing potential access points and having a professional treat with a liquid residual insecticide under the eaves, around windows, and the foundation

Smokybrown cockroach activity can sometimes be identified by their fecal spots. While sometimes the droppings can resemble mouse droppings, their activity can also be identified by fecal smears on surfaces (see below).

The Smokybrown Cockroach

Normally An Outdoor Pest- The Smokybrown Cockroach

The smokybrown cockroach, Periplanata fuliginosa (Serville), is a somewhat large peri-domestic cockroach. A peri-domestic cockroach is a cockroach that most of the time can live and breed outdoors, but sometimes they can inhabit the living spaces of a building. This is an important term to know, whereas domestic cockroaches live and breed solely indoors. A great example of a domestic cockroach is the German cockroach. German cockroaches cannot live and breed outdoors- they solely depend on indoor environments to survive.

Smokybrown cockroaches have a dark mahogany color and can be a little longer than an inch in size as an adult. Both males and females have wings and can readily fly. A smokybrown cockroach has a lifespan of approximately 200 to 300 days. Females typically glue their egg cases to surfaces. Their dark egg cases can readily be seen in cracks and crevices when inspecting a home which has smokybrown activity.

These egg cases can hold 24 eggs each, and adult female smokybrowns produce about 17 egg cases in their lifetime. These cockroaches normally feed on plant matter outside and other decaying organic matter. They can gain access indoors by either being brought in on firewood or other items stored outside, they can gain access around gaps in windows and eaves, or they can gain access by entering open garages.
