Smoky Brown Cockroach Appearance:
This roach is very similar to the American roach, but
is smaller in size and is dark brown-mahogany, black in color.
Adults have well-developed wings that stretch to the tip of the abdomen.
Smoky Brown Roach Diet:
Normally they prefer plant material, but will eat almost
anything when they come inside the home.
They feed on plant material and may inhabit greenhouses.
Habits and Biology of Smoky Brown Cockroaches:
The smoky brown is a tropical cockroach,
thus more common in the southern United States.
This species is occasionally shipped all over the U.S.
on fruit or nursery stock.
They enter houses in the summer or hitchhike on firewood.
Females lay a dark brown capsule that contains 24 eggs,
hatching in one to two months.
The young will become an adult in 10-12 months.
This roach is not usually found in the Northern States unless they are
brought
in.
However, in the Southern part of the country they are numerous.
These roaches fly at night toward lights.
Recommendations for Smoky Brown Roach Control:
- Caulk all penetrations through ground level walls.
- Stop water leaks, screen equipment overflow drains,
and take overflow water away from buildings; keep drain traps full or
capped.
- Remove rotting leaves from window wells.
- Move garbage cans out of preferred moist habitat.
- Ventilate moist spaces.
Generally speaking, control measures should concentrate
on the outside of the building and points of entry. This is called a "perimeter
or barrier" treatment.
Use a good residual sprays such as :
- Talstar One*Top
recommendation (Broader label and longer lasting-may be used
on ornamentals as well.
Talstar
One
- Cyper WP
Cyper WP
- Demon WP
Demon
WP
You may use three residual sprays : Talstar One , Cynoff WP(Cyper WP)
or Demon WP inside or outside
Spray outside around doors, windows, pipe openings, and dryer vents.
Apply also on the inside on the baseboards near the entry pts.
On the inside-apply around the plumbing under the sinks and washer and
dryer connections. You don't have to spray all the interior baseboards,
just the corners and baseboards inside the garage and basement areas.
For additional treatment you may apply
granulars around the base of the house, particularly in areas of pine
straw and mulched areas.
Two recommended granulars are : *Top
recommendation(longer lasting)Talstar One or Bifen IT Granulars
If you have these larger cockroaches entering inside your
home from the attic area (due to trees that overhang the attic or gutters
that are not clean) using baits like Niban /Intice insect baits,
would give you very good results.
Intice Bait
Niban or Intice Baits would also be excellent choices for
crawl spaces and or attics.
The residual insecticides : Talstar
One , Cyper WP, and Demon WP as well as the residual granulars: Talstar
or Bifen LP Granules should be repeated
every three months during the season.
The Intice baits last from 6 months
to a year, free from rain. Feel free to call if you have any questions.
