These roaches look like the German cockroach. They lives both indoors and out. What makes them distinctive is that they are strong fliers, that are attracted to lights at night. They have become a particular pest where well-lit urban shopping malls are adjacent to agricultural areas, such as citrus groves. They turn up in shops, restaurants, planters, vending machines, and people's homes.
Cockroaches seek warmth, moisture and food.
They hide during the day in sheltered, dark places in the home, and come out at night to forage. They feed on garbage and human food. Because of this, they may transmit human diseases, particularly those caused by food-poisoning organisms. Some females carry the capsule with them until the eggs hatch. Cockroaches contaminate and spoil human food.
