Cockroaches

They are the most common household insect in the US, with more than 3500 species. They live in just about any warm environment. They feed on just about anything edible including toothpaste, soap, pet food, glue, etc. Roaches often carry disease, and are very hard to get rid of. They are cannibalistic, eating other insects and roaches, and can survive for a long time as long as there is something to eat. There are several different types of cockroaches, a few of the most common detailed as follows:

American Cockroach

Size: 1” to 2”

Description: American cockroaches are reddish brown, and are also called a waterbug or palmetto bug. They live inside sewers, and as the sewers dry up, they are forced to look for a new environment. They are often attracted to the moisture of a yard and bushes, and ultimately inside where there is a constant source of food and water.

Life Cycle: Eggs can take several years to hatch, depending on temperature, so it will often take awhile for them to be noticed inside. Usually once they are noticeable, there is a large colony inside the home.

Description: These flying black roaches are also often called waterbugs. They spend most of their time outside, and come out during nights. They can make a home most places, and can climb through structures by climbing along the outside of water pipes.

Life Cycle: Eggsacs, also called ootheca, are laid after being formed inside the body. Each cycle over 200 eggs are laid. Again, it can take a few years for roaches to reach adulthood.

Description: These light brown roaches have two black bands along their back. They are the most common roach, and have the highest cause of insect disease and sickness. They prefer humid environments, and thrive in any places with food, such as bathrooms, kitchens, and bedrooms. They can be introduced to a home through shopping bags, migrating from one house to another, or from plants outside. They carry pathogens that cause food poisoning, strep throat, diarrhea, dysentery, cholera, polio, and hepatitis B.

Life Cycle: Similar to other cockroaches

Brownbanded

Description: These light brown cockroaches are names because of the brown bands that run across the wings of the adults. They prefer very warm areas, and so are often found around appliances, light switches, furniture, and near motors. These roaches also like to eat glue based foods and starches, as well as dead skin cells, so can often be found around dirty clothing. They also carry many diseases similar to the german cockroach.

Life Cycle: Eggs take about a year to reach maturity. The female carries the ootheca for 24 hours before attaching it to the side of a structure. Each ootheca contains about 15 eggs, and each cockroach will lay 10-15 capsules.
