Physical Characteristics

The smokybrown cockroach is large – 1 1/4 to 1 1/2 inches – and typically mahogany colored, as its name implies, ranging from deep brown to black, with a uniform, shiny coloration. Wings extend beyond the roaches’ abdomens.

Smokybrown Cockroach

If you’ve got roaches in your attic, chances are it may be the smokybrown cockroach. This roach is usually found outdoors in moist, dark and warm places, away from airflows that can dry them out – the smokybrown roach’s exoskeleton doesn’t hold moisture as well as other species’ cuticles. But this roach can find its way into structures through cracks in the roof. Both sexes are good fliers, and are attracted to lights. Once inside, they’ll feed on anything nutritious.

Check your attic. Exclusion is the money word here; if you find smokybrown roaches, you want to seal off any entry points with caulk or screening. Switching from white to yellow lighting around entryways may help. A call to Clark for expert advice on how to solve your smokybrown roach problem may be a prudent idea, too.
