Why Do Cockroaches Turn Black?

You may wonder why cockroaches turn black. Cockroaches are nocturnal and have a tendency to scatter when disturbed. They are white when they are young but gradually transform into black as they mature. This color change is the result of a metamorphosis. The young cockroaches are not reproductive and lack wings. They are the most common stage of cockroach populations in the field.

Cockroaches eat a wide range of foods. They are nocturnal, which means that they spend most of their day hiding and only come out at night to feed. They feed on dead insects, decaying plants, sewage, and organic matter. Cockroaches like starchy foods, such as the ones found in cardboard or book bindings. This pest is very resourceful and lives in sewers, drains, and gutters.

Oriental cockroaches are black, shiny, and small. They measure about an inch and a half long. Males have wings, but they are not functional. They have a musty odor. The Oriental cockroach lives in damp, moist areas and emits a foul odor.

Oriental cockroaches are primarily outdoor insects, but they can enter homes during hotter months. Their habitats tend to be cool and damp, so they are at home in basements and other damp areas.
