The answer to 'types of cockroach' is that there are several common species of cockroach that can infest homes, including the American cockroach, German cockroach, and Oriental cockroach. These cockroaches differ in size, color, and behavior, but they all share the ability to spread diseases, contaminate food, and trigger allergic reactions.
The American cockroach is the largest household cockroach, reaching up to 2 inches in length. They are reddish-brown in color and can often be found in damp areas like basements, sewers, and drains. The German cockroach is the most common indoor cockroach, measuring about 1/2 to 5/8 inch long. They are light brown in color with two dark stripes behind the head. The Oriental cockroach is a dark, shiny black or brown color and is about 1 to 1 1/4 inches long. They prefer cool, damp environments like under sinks, in basements, and in cracks and crevices.
