Common Types of Cockroaches

While there are many types of roaches roaming the planet, the four most common ones found infesting homes and businesses in Florida are the American cockroach, the German cockroach, the Australian cockroach, and the Asian cockroach.

American Cockroaches

Dark reddish brown in color, American cockroaches have a lighter color outlining their bodies and a distinctive yellowish figure-eight pattern behind their heads.  This type of roach has wings longer than its body and is capable of flight.  Growing up to two inches in length, they are one of the largest roaches in the U.S.



German Cockroaches

German roaches are light brown or tan, have two distinctive black stripes running horizontally behind their heads, and flat, oval-shaped bodies.  Like American roaches, German cockroaches have wings but do not fly.  German roaches are small, growing up to 5/8 of an inch in length.



Australian Cockroaches

Very similar to the American roach, Australian roaches are also reddish-brown in color.  They have a bright yellow border that surrounds a black spot on their heads.  This type of cockroach also has wings that extend past abdomens but they rarely fly.  Unlike American roaches, Australian cockroaches are smaller bugs.  These roaches are highly attracted to sources of light.



Asian Cockroaches

Asian roaches look very similar to German roaches; they are brown in color and have long, narrow wings that extend past the end of their abdomen.  They are winged roaches and readily fly. They grow up to 1 inch in length. 


Are cockroaches dangerous?

Yes, cockroaches are dangerous. Cockroaches have the potential to spread a wide variety of diseases and infections including dysentery, salmonellosis, gastroenteritis, and E. coli. Cockroach droppings, their saliva, and shed skins can trigger allergies and asthma attacks - especially in children.

Their saliva and excrement have also been found to contaminate food sources, food preparation surfaces and storage areas, utensils, bowls, and other items.

What attracts cockroaches?

Generally speaking, roaches are attracted to warm, moist environments. Leaking pipes and fixture and excessive moisture problems may attract these pests.  Potential food sources are another attractant and include trash, compost piles, pet food, scraps of food around a grill, and crumbs on the ground or between kitchen appliances as well as fruits and vegetable that have fallen to the grounds. Some roaches are also attracted to light.

Where are cockroaches found?

Where you are likely to see roaches depends on the type of roach.  For example, American roaches nest in mulch, trees, and inside sewers.  Inside, they seek out warm, humid areas like kitchens, bathrooms, and basements.  German roaches also take up residence in kitchens and are often found in cupboards and drawers as well as behind appliances.  It’s not uncommon to find them under sinks in bathrooms and in basements and laundry rooms where it’s warm and humid.  Australian roaches are commonly discovered in greenhouses, crawlspaces, and attics.  Outside, they’re found underneath tree bark, in firewood piles, mulch, gardens and potted plants, and underneath rocks.  Asian roaches are rarely found inside but can be found flying around TVs, computer screens, and light fixtures.  Outside you may notice them around porch lights and in spots, similar to Australian roaches.
