The
brownbanded cockroach is light gold to glossy dark brown, and is 1/2 to
5/8 inch long. It has transverse yellow bands across the base of the
wings and across the abdomen. The wings of adult males cover their
abdomens, while the females' wings are shorter. The yellow bands across
the back are more pronounced on nymphs than on adults.
- Brownbanded
cockroaches are more apt to be found in homes, apartments, hotels,
motels, nursing homes and hospitals than in restaurants, grocery
stores and other commercial establishments. They prefer starchy
foods and appear to have lower water requirements than other
cockroaches. They can occupy drier locations within a building.
Nymphs and adults frequently are found on ceilings in dark or dimly
lit rooms, behind picture frames, in light switches, in upper walls
of cabinets and closets, or on undersides of furniture and inside
upholstered furniture. Because brownbanded cockroaches are found in
so many locations they may be more difficult to control.
- These
cockroaches are quite active, and the adults, especially the males,
fly rapidly when disturbed. Both adults and nymphs may jump to
escape danger. The adult female carries her egg capsule for only a
day or two before gluing it to a protected surface underneath or
inside furniture, in a closet or on the ceiling in a darkened room.
They can also be found in televisions and other appliances.
- HABITAT: They prefer
to hide in warm, elevated areas near the ceiling, behind wall
decorations and loose wallpaper, in closets, beneath or inside
upholstered furniture, and in electrical appliances such as TV sets,
stereos, radios, and toasters. They develop and live throughout the
building, making control difficult. No room or furniture is immune
to infestations, and one may find tiny, dark droppings and cast
skins on cabinets and shelves. The roaches are commonly transported
in furniture, luggage, and other items in houses and soon develop
into annoying infestations under warm, humid conditions.
- LIFE
CYCLE: Egg capsules are about 1/4 inch long and reddish-brown.
Brownbanded cockroach females deposit egg cases in clusters on
furniture, draperies, wall decorations, shelving and ceilings. The
egg capsule contains 14 to 16 eggs; a female produces 10 to 20 cases
in her lifetime. Eggs hatch in 50 to 75 days and nymphs develop in
90 to 270 days, with adults living 150 to 200 days.
- TYPE
OF DAMAGE: Roaches can foul food, damage wallpaper and books, eat
glue from furniture and produce an unpleasant odor. Some homeowners
are allergic to roaches. The pests can contaminate food with certain
bacterial diseases that result in food poisoning, dysentery, or
diarrhea.
- CONTROL:
Control is difficult-treatments must be extensive or directed at
population sources determined by bait trapping. Traps can determine
infestation severity and monitor chemical controls, especially with
brownbanded and German cockroaches.
