Cockroaches are insects belonging to the order Blattodea. They have flat, oval bodies and long antennae, which help them navigate their environment. There are over 4,500 species of cockroaches, but only a few are commonly found in homes. They are known for their ability to survive in various conditions and can live for weeks without food. These insects are primarily nocturnal, meaning they are most active at night. Cockroaches are omnivorous, feeding on a wide range of organic materials, including food scraps and decaying matter. While they are often considered pests, they play a role in the ecosystem by helping to break down waste.
