What You Can Do

Habitat removal where these pests live is an effective way to help reduce their populations.

Appearance

  • Color: They are reddish-brown to dark brown with yellow markings on the top of their head and the front edge of each wing.
  • Size: They are slightly smaller than American cockroaches . Their wings are about 1 1/4 to 1 1/2 inches long.
  • Characteristics: They are also known as shad roaches. Their wings extend over the abdomen.

Diet

They feed primarily on plant material, but inside the home they will feed on starchy materials.

Habitat

Australian cockroaches are most commonly found in yards. They live primarily outdoors, but can also be found indoors. They prefer to live under moist and sheltered areas such as:

  • Drains
  • Greenhouses
  • Piles of firewood
  • Sinks
  • Toilets
  • Tree bark
  • Water pipes

Geographic Range

These cockroaches are widespread throughout Florida and other coastal states in the Southeast. They are also known as shad roaches.

Life Cycle

Their life cycle includes eggs, five nymph stages, and the adult stage. In total, it takes about one year for complete development.

Female Australian cockroaches carry their eggs in cases, and a healthy female will produce about 20-30 egg cases during her lifetime. Each egg case contains about 25 eggs.
