A recent survey indicated that the cockroach was the most despised creature, beating out snakes, rats, bats, and spiders.
The German cockroach or Blatella germanica is consider it to be a pest because it invades where we live, eat and sleep. Between 4000 to 7500 different species of roaches. Of this amount, only one percent are considered to be a pest. Some of the other more common species are
- Oriental Cockroach – Blatta Orientalis
- American Cockroach – Periplaneta Americana
- Brownbanded Cockroach – Supella longipalpa
Their mouths are used for chewing, not biting. Most roaches are nocturnal, that is, they prefer the night and are sensitive to all forms of light except for the red spectrum. They are most active right after dusk and right before dawn. They prefer to live in warm moist places and are more abundant in tropical areas. However, they can live in almost any environment and they have been found in the North and South Poles.
The German Cockroach is 5/8 inches in length and is brown in colour. There are two prominent black stripes running down the broad shield behind the head. This nasty little guy will eat almost anything – even hair and fingernails. This insect is common in areas with access to food and water. The lige cycle from egg to adult takes about a month, and populations can become huge if not kept under control.
The American cockroach is the largest of the common periodomestic cockroaches. It is also known as the Palmetto bug or water bug. As an adult, they are dark red/mahogany in color, with a yellowish border on the promotum. This yellowish border may make the pronotum appera to have two spots in the middle. The body is typically one and one quarter inches in length.
