The American cockroach is a large species of cockroach, typically measuring about 1.5 to 2 inches in length. It has a reddish-brown color with a yellowish figure-eight pattern on the back of its head. This insect is commonly found in warm, humid environments, such as basements, kitchens, and sewers. American cockroaches are omnivorous scavengers, feeding on a variety of organic materials, including food scraps and decaying matter. They are known for their ability to reproduce quickly, with a single female capable of producing hundreds of offspring in her lifetime. While they are not harmful, they can carry allergens and pathogens.
