Cockroaches can be found in all 50 states.

American Cockroaches

The American cockroach is the largest of the house-infesting cockroaches.

Color: Reddish brown, with a yellowish figure 8 pattern on the back of the head.
Legs: Six
Shape: Oval
Size: 2 inches
Antennae: Yes
Flying: Yes
Region: All 50 states

Habits

American cockroaches are found in food processing areas and food storage areas, as well as other types of buildings. They are active when the temperature is 70 degrees or higher, but they can survive lower temperatures with the right conditions.

Habitat

American cockroaches are often found in sewers and basements, particularly around pipes and drains.

Threats

Cockroaches have been reported to spread at least 33 kinds of bacteria, six kinds of parasitic worms, and at least seven other kinds of human pathogens. They can pick up germs on the spines of their legs and bodies as they crawl through decaying matter or sewage and then carry these into food or onto food surfaces. Germs that cockroaches eat from decaying matter or sewage are protected while in their bodies and may remain infective for several weeks longer than if they had been exposed to cleaning agents, rinse water, or just sunlight and air. Recent medical studies have shown that cockroach allergens cause lots of allergic reactions in inner city children. They were even shown to cause asthma in children. These allergens build up in deposits of droppings, secretions, cast skins, and dead bodies of roaches.

Good sanitation and habitat reduction, along with vacuuming, surveillance, a baiting program, and some sealing of cracks can usually quickly reduce or eliminate a cockroach population.

Brownbanded Cockroaches

Description

Brown banded cockroaches get their name from the two lighter bands they have across their dark brownish bodies. In addition to the distinctive banding, males have full wings, which reach beyond the tip of their rather pointed abdomens, but females have underdeveloped wings, much shorter than their broad, rounded abdomens. The lighter band markings are much more distinct in nymphs than in adults of either sex.

Pest Facts

Color: Brown, with pronounced banding across wings
Legs: Six
Shape: Oval
Size: 1/2 inches
Antennae: Yes
Flying: Yes
Region: All 50 states

Habits

Male brownbanded cockroaches have been observed to fly indoors. Among cockroach species, brownbanded cockroaches have the most distinctions between sexes. Females have larger abdomen and shorter wings than males. Brownbanded cockroaches often hide their egg cases in or under furniture.

Habitat

Within a room, these roaches tend to prefer warmer, drier, and higher locations than do any of the other urban pest roaches. They are often found in upper cabinets or in rooms other than kitchens (food preparation areas) or bathrooms.

Threats

Cockroaches have been reported to spread at least 33 kinds of bacteria, six kinds of parasitic worms, and at least seven other kinds of human pathogens. They can pick up germs on the spines of their legs and bodies as they crawl through decaying matter or sewage and then carry these into food or onto food surfaces. Germs that cockroaches eat from decaying matter or sewage are protected while in their bodies and may remain infective for several weeks longer than if they had been exposed to cleaning agents, rinse water, or just sunlight and air. Recent medical studies have shown that cockroach allergens cause lots of allergic reactions in inner city children. They were even shown to cause asthma in children. These allergens build up in deposits of droppings, secretions, cast skins, and dead bodies of roaches.

Prevention

Good sanitation and habitat reduction, along with vacuuming, surveillance, a baiting program, and some sealing of cracks can usually quickly reduce or eliminate a cockroach population.

German Cockroaches

The German cockroach is by far the most important and usually the most common of the cockroaches.

Pest Facts

Color: Light brown to tan, with two dark, almost parallel stripes located on their backs, just behind their heads
Legs: Six
Shape: Segmented; oval
Size: ½-5/8 inch
Antennae: Yes
Flying: Yes
Region: All 50 states

Habits

German cockroaches can be found throughout structures but show a preference for warm and humid places. They are usually found in kitchens and secondarily in bathrooms, but infestations often occur in rooms where people eat and drink.

Habitat

German cockroaches prefer to live in cracks and crevices near food sources and spend 75% of their time in such harborages. German cockroaches prefer to live close to sources of food and water, hence their affinity for residential and commercial kitchen environments.

Threats

Cockroaches have been reported to spread at least 33 kinds of bacteria, six kinds of parasitic worms, and at least seven other kinds of human pathogens. They can pick up germs on the spines of their legs and bodies as they crawl through decaying matter or sewage and then carry these into food or onto food surfaces. Germs that cockroaches eat from decaying matter or sewage are protected while in their bodies and may remain infective for several weeks longer than if they had been exposed to cleaning agents, rinse water, or just sunlight and air. Medical studies have shown that cockroach allergens cause lots of allergic reactions, especially in children. They were even shown t cause asthma in children. These allergens build up in deposits of droppings, secretions, cast skins, and dead bodies of roaches.

Prevention

Good sanitation and habitat reduction, along with vacuuming, surveillance, and baiting program, and some sealing of cracks can usually reduce or eliminate a cockroach problem. The reduction of moisture sources, such as leaking pipes, is also helpful.
