👉 Roach is a small, brown insect that feeds on insects, such as ants, termites, and other small animals. Its diet can vary depending on its habitat, but it primarily eats insects, specifically those of the order Coleoptera, which includes ants, bees, wasps, and flies. Roaches are often found in gardens, parks, and other urban environments where they can thrive due to their ability to climb over fences and walls.
