Cockroaches

American cockroach – Periplaneta americana

Appearance

These are the largest of the cockroaches that infest homes. They can be up to 2 inches long, and are reddish-brown in color. They are often called “water bugs” or “palmetto bugs.” The most distinguishing mark is a yellow figure 8 type shape on the front of the body.

Behavior

The American Roach likes warm moist places. They often will accumulate around kitchen areas in homes because of the harborage. Capsules laid by females will contain 14 young and in summer months a single female can produce up to 24 capsules. Because they are scavengers they will eat almost anything from glue to food crumbs.

Habitat

They are relatively aggressive and prefer warm damp areas. This species is more likely to be seen during the day, and will often establish themselves in kitchens.

Control Advice

In order to effectively control American Cockroaches their food source must be found. It will usually be necessary to hire a professional company, such a Precise, to obtain a long-term solution to the problem. Crawls spaces, attics, and especially cracks in the exterior of homes are often entry points for the American Cockroach.

Brown Banded Cockroach – Supella longipalpa

Appearance

The male and female vary in appearance. Males are a light brown, while females are reddish brown to dark brown. They are both around a 1/2 inch long. The most distinguishing mark of the Brown Banded cockroach is the lighter colored bands which run across the wings.

Behavior

Brown Banded cockroaches will occupy most of their time in cracks and crevices with pressure on their bodies. This species is largely nocturnal and will come out of hiding only when they feel it is safe. They crave high temperatures, and need moisture, but not to the extent that some other species. They can therefore be found throughout homes. Because they have a relatively short nesting period they can increase populations quickly, almost rivaling those of the German cockroach.

Habitat

They are scavengers and will eat almost anything. They have been known to eat book binding glue and glue used in cabinets. They can be found throughout the home in the wall voids, attics, bedrooms, living rooms, closets, and even bookcases. However, they most often nest in kitchen and bathroom areas. Because they prefer warmer temperatures they will often be found in overheated homes and dwellings. These roaches will also often seek harborage in cardboard boxes, which offer both shelter and a food source.

Control Advice

There are several steps you can take to help control populations: make sure no pests are accidentally getting into the home in bags etc, do not store paper bags under sinks, and seal any obvious cracks. Because they can be found throughout the home these can be extremely hard to control. They require a lot of food and harborage and so limiting any of those factors will help to decrease populations. In order to effectively decrease populations it is often necessary to hire a professional service, such as Precise, to accomplish this task.

German Cockroach Size

Appearance

The German cockroach is brown in color and about 1/2 inch long. The distinguishing marks are the two black longitudinal stripes on the head.

Behavior

German cockroaches are the most difficult cockroach to control. They multiply at dizzying rates. The capsules laid by females contain 30-40 eggs per capsule, and the eggs reach adult faster than any other residential cockroach. As populations grow and harborage becomes scarce they will begin foraging for new areas. The foraging generally happens just before dawn and after dark. German cockroaches forage in a predictable manor and will generally not leave harborage unless it is necessary.

Habitat

They require high moisture, and this is why they are most likely found in kitchen and bathrooms. They will rarely leave their hiding spots, and will always congregate around a food and water source. They are scavengers and will eat almost any food source they come across.

Control Advice

German cockroach control is extremely difficult and requires persistence and expertise. Because they multiply so quickly and are difficult to control it is often necessary to call a professional, such as Precise, to control the population.

Oriental Cockroach – Blatta orientalis

Appearance

Oriental cockroaches are dark-brown to black in appearance. They will be about 1 inch long. The most distinguishing mark of the Oriental cockroach is its extremely long antennae. The male and female differ in appearance, but both have long antennae.

Behavior

The Oriental Roach is a pest for many homes in the United States. During the summer they often will venture outdoors as the weather cools they close in on homes. They do not reproduce as quickly as some species, but in favorable conditions populations can rapidly increase.

Habitat

Oriental Roaches most often establish themselves in crawl spaces, wall voids, and basements. They will feed on garbage, sewage, any decaying organic matter, and especially starches. Because of their preference for starches they will usually be found in the kitchen. They will enter the home through sewer, storm, and floor drains, and any cracks in the exterior of the home.

Control Advice

Eliminating harborage from around the home especially mulch and landscape rocks decreases the chances of infestation. Sealing any cracks around the exterior of the home also prevents entrance into the home.
