Cockroaches are insects belonging to the Order Blattodea. They represent a primitive and highly successful group of animals whose origins extend back at least 300 million years.

Typically, infestations of cockroaches develop in and around buildings and other structures that provide food, shelter and often the preferred conditions of temperature and humidity. A commercial kitchen may support hundreds or even thousands of cockroaches.

Cockroaches may be carried from place to place as live individuals or as egg cases, in foods and food packaging, luggage, furniture, buses, trains, ships and aeroplanes.

Cockroach Control

Effective control of cockroaches often relies on a knowledge of their foraging and breeding habits. Many homeowners attempt to use a ‘do it yourself’ cockroach control remedy with the results often doing very little or nothing at all.

Small problems such as the odd one or two cockroach in the Kitchen can develop into larger ones.

Treatments must be targeted to your specific cockroach species in order to solve the problem, whilst ensuring the safety of your family and pets. A thorough knowledge of cockroach behaviour and biology is essential.

Cockroach Prevention

Once the cockroach infestation has been treated, preventative methods can be implemented to stop them from coming back.

One particularly important prevention method is maintaining a high level of cleanliness and hygiene.

All areas indoors should be free of food crumbs and liquid spills. Common surfaces that are often covered with crumbs and other liquids, include kitchen benches, shelves and drawers, floors, tables, chairs and so on. Food utensils, should be washed up soon after use and not left in the sink for long periods.

Outdoor areas should be free of food sources such as bird seed, dog food, left-over party food.
