A "roach" is a common term for a type of cockroach, which belongs to the order Blattodea. These insects are known for their flat, oval bodies and long antennae. Roaches are typically brown or black and can be found in various environments, often in warm and humid areas. They are nocturnal creatures, meaning they are most active at night. Roaches are omnivorous scavengers, feeding on a wide range of organic materials, including food scraps and decaying matter. They can reproduce quickly, leading to infestations in homes and buildings. Effective pest control methods are often necessary to manage their populations and prevent health risks associated with their presence, such as allergies and disease transmission.
