Periplaneta fuliginosa (Serville)
The Smokybrown cockroach is closely related to the American
cockroach , but is a uniform shiny, dark-brown or mahogany color. It is
about 1 ¼ to 1 3/8 inches long; the wings of both sexes cover the abdomen. The
female Smokybrown has a broader abdomen than that of the male and lacks styli.
Young nymphs have white markings on the thorax and abdomen, and on some antennal
segments. Older nymphs are uniformly dark brown. Reported in Florida as
early as 100 years ago, this roach has become a major pest in many parts of the
United States. It is most prevalent in the moist regions, Gulf Coast
states and southern and eastern portions of Mississippi. Due to its large
size and the speed at which it moves, this is not one of the most popular
visitors in any home. Image
The Smokybrown cockroach has a great tendency to lose moisture through the
cuticle and thus requires water every two to three days. These
requirements are important to remember when implementing your roach
extermination program. This pest is most likely found in areas which
are protected, moist, dark, relatively warm and free from the desiccating
effects of air flow. In nature, tree holes and the canopies of palm trees
offer the ideal environment in which this bug can thrive. The home equivalent
of these conditions include:
- Block Walls
- Flower Beds
- Any Mulched Areas
- Attics or Soffits with Moisture Problems
- Damp Basements
- Any Dark, Poorly Ventilated Area
Smokybrown cockroach elimination:
- Eliminate or alter any conditions which encourage the presence and/or
reproduction of the roaches. These pests thrive in dark, humid areas
which have little or no air flow.
- Spray exterior of structure with Ficam W,
WP or Cynoff WP. These odorless
insecticides will give a quick knockdown of bugs while lasting for several
weeks, usually yielding about 90 day residual. Spray any crack,
crevice or entry point on the outside of the structure. This includes
treating around all windows, doors, vents and in weep holes of brick veneer.
Also spray tree trunks, from ground to crotch of tree, but no higher than
six feet. All mulched areas should be sprayed with your insecticide.
These exterior surfaces should be treated 3 to 4 times
- If necessary, spray indoors in the following areas: basements, garages,
carports, attics, closets, laundry rooms. Also treat beneath and
behind large appliances (refrigerators, stoves, etc.) or other areas where
these roaches prefer to hide. (Spraying all of your baseboards with
any bug spray is not necessary!)
Indoor areas should be treated 2 to 3 times per year.
- Hollow blocks or other areas such as behind brick walls and along
plumbing lines should be treated with Delta Dust.
Although many dusts will kill roaches, Delta Dust
is water-proof and will not be destroyed by the moist habitat of the
Smokybrown as would other dusts. For deeper penetration and better
distribution of your insecticide dust, use a Crusader
Delta Dust should be used
once each year or as needed.
