Oriental Cockroach

Oriental cockroaches (Blatta Orientalis) are peridomestic, living around humans in factories, hospitals and domestic dwellings. Oriental cockroaches can survive outside under ivy and in drains. The adult cockroaches are 22-27mm in length, are black in colour and like damp areas of the buildings. The female will produce around 16 egg cases (ootheca) in her life time, each containing 16 young (nymphs).  Oriental cockroaches are omnivorous, feeding on both plant and animal matter.

Health Risk

Oriental cockroaches are a serious pest problem in buildings, as they carry a variety of disease causing organisms that cause food borne illnesses. These can easily be transferred to foodstuffs and food preparation areas. The cockroaches also cause physical contamination through their body parts and droppings being deposited in or on foodstuffs. These fragments can also cause allergies and asthma. Proprietors of buildings and food producing establishments have a legal obligation to rid their premises of insect infestation. Other reasons for control include loss of reputation and goodwill, fear and financial loss to businesses.
