Two dark stripes running lengthwise on the pronotum
Adults are fully winged but rarely fly
Thrive in all types of buildings, but are found most often in homes,
apartments, condominiums and commercial food establishments
Usually seek dark shelters near moisture and food, such as kitchens and
When populations become large and food scarce they can appear in
bedrooms and other less likely places
Brownbanded Cockroach (Supella longipalpa)

Often enter and thrive in homes, commercial establishments and other

Live mainly in dark, moist sites in kitchens, bathrooms, basements, steam
tunnels, sewers and even in crawl spaces under buildings.

Female's wings are reduced to mere lobes
Not capable of flight
Do not move very fast even when disturbed
Usually found near decaying organic matter.
During warm humid weather they inhabit lawns, compost piles, flowerbeds
In periods of drought or with the approach of cold weather they move in
masses into homes and other buildings.
In buildings they inhabit high moisture areas such as sewers, drains and dark,
Activity is somewhat restricted to the ground or below ground levels of
Commonly found in Western Texas and the Texas Panhandle.
Cockroach Prevention Measures
Preventive measures are the key to successful control. It is easier to prevent
a cockroach invasion than to control an established population. The success
of preventive measures requires care, Planning and sustained effort.
Cleanliness in the home and elimination of favorable breeding sites lessens
the possibility of cockroach infestations and reduces the need for pesticides,
but these practices WILL NOT ALWAYS prevent invasions from outside
Cockroaches and their likely habitats should be identified before any
Homeowners can detect conditions that will foster the development of
infestations through frequent inspections.
Proper sanitation, both indoors and outdoors, effectively limits cockroach
Do not leave unwashed dishes, kitchen utensils, and uncovered food out
Clean up all spilled liquids.
Areas beneath and behind cabinets, furniture, sinks, stoves and refrigerators
should be cleaned often, as should cupboards, pantry shelves and storage
bins where particles of food frequently accumulate.
Kitchen waste and excess refuse should be kept in cockroach proof
container and disposed of as frequently as possible.
Dry pet food should be stored in tight containers away from the kitchen and
If pets are fed indoors, leftover foods should not be allowed to remain in the
feeding dish overnight.
Outdoors, garbage cans, racks, platforms or slabs should be cleaned
Discourage cockroaches from entering the home by sealing any cracks of
1/8 in or more in the foundation and exterior walls.
Check the seal or caulking around air conditioning unit, windows, doors,
pipes or other openings into the home.
Inside the home eliminate all possible hiding areas and food sources.
Repair cracks and holes in floors, walls and ceilings.
Seal openings around plumbing fixtures, furnace flues, electrical outlets,
windowsills and walls, and along baseboards and ceiling moldings.
Leaky water faucets and pipes should be repaired.
Thresholds on doors should be as tight as possible and cracks in porches
and stoops should be sealed.
Eliminate hiding Places:
Paper, Cardboard, lumber, firewood and other debris next to the home
provide excellent refuge for several cockroach species.
Keep yard trash and stacks of firewood away from the home or garage to
minimize the chance of cockroach invasion
There are a number of cockroach traps that are inexpensive, convenient to
use, disposable and contain no toxic insecticide.
Most are about the size of a large matchbox, that are open at both ends and
have the inside surface covered with a very sticky adhesive. (The adhesive
immobilizes cockroaches that enter the trap.)
Some may contain a slow release food attractant.
Trapping alone will not eliminate cockroach populations, but must be used in
conjunction with preventive measures for maximum effectiveness.
Trapping can reveal the hiding places and the severity of infestation, help
monitor the effectiveness of control measures and detect population
increases which may require an insecticide treatment.
Traps should be placed where cockroaches are likely to travel to and from
feeding and hiding areas. It is best to place traps against walls and in corners
where both ends are unobstructed. Reposition the traps if no cockroaches
are caught after two or three nights. The number of traps required for a home
or building will vary with the kind of cockroach present and the severity and
location of the infestation.
