The Australian cockroach is larger and darker in colour and has a distinctive lighter marking near the head, these cockroaches inhabit gardens and are often seen underneath mulch or heavy ground leafed areas. These nocturnal creatures hide during the day and become active at night in order to find food.
Most cockroaches rest in cracks and crevices and hide in the security of enclosed surfaces. They are an incredibly resilient pest that seems almost indestructible. They can contaminate food products, utensils and various areas with droppings and skins. Some people may be allergic to cockroaches and develop skin irritations or asthmatic problems. This occurs when food is contaminated by cockroaches and ingested by humans.
