Cockroaches are one of the most significant public health pests, carrying diseases such as Typhoid, Dysentery, Poliomyelitis, Gastroenteritis and Salmonella.
They are more commonly found in commercial premises where food is being produced or handled, such as restaurants and catering establishments. However, they are just as common in domestic settings where they live in kitchens and drains.
Cockroaches are nocturnal insects, that spend the daytime hours hiding in crevices and cracks close to sources of food and water, such as kitchen appliances, around sinks and in electric sockets to name a few.
