Roaches, commonly known as cockroaches, are insects belonging to the order Blattodea. They are characterized by their flat bodies, long antennae, and rapid movement. There are over 4,500 species of roaches, but only a few are considered pests. They thrive in warm, dark environments and are often found in homes, restaurants, and other buildings. These insects are omnivorous, feeding on a variety of organic materials, including food scraps and decaying matter. Roaches are known for their resilience and can survive in harsh conditions, making them difficult to eliminate once they infest an area. Proper sanitation and pest control measures are essential to manage their populations.
