Fossil evidence shows that cockroaches have existed almost unchanged for more than 250 million years and have been described as “God’s Perfect Creature”. They are amazingly adaptable and hard and can live and breed under hostile conditions.
The three main pest types in building are:
- American Cockroach (Periplaneta Americana)
- German Cockroach (Blattala Germanica)
- Brown banded Cockroach (Supella Longipalpa)
They prefer a warm and moist habitat close to food sources e.g. kitchens, rubbish chutes and toilets. Due to their close association with filth (feeding and breeding in highly unsanitary environment like sewers, garbage dumps and drains) and their indiscriminate wandering in kitchens and pantry, they are capable of spreading diseases.
Indicators of their existence are the telltale odor, droppings, egg capsules (ootheca), damage packaging especially of food and moulted body shells.
In addition to residual treatment, baiting is a popular method for cockroach control. Cockroach baits are usually formulated in bait stations as gel. Unlike residual treatment, baiting is the application of insecticides in gel form in limited amounts to areas where cockroaches will forage for food. Due to its limited application, it is relatively safer than residual treatment. It is also odorless and ready to use. Cockroaches will feed on the bait, receive a lethal dose and eventually die.
This treatment is extremely useful in sensitive environments such as food preparation counters, bakery, and computer room where residual treatment is not allowed.
RECOMMENDATION FOR THE RESTRICTION OF COCKROACH
Control must include precautions to restrict the import of crawling insects into the premises. This is their main method of entry. Cockroaches and most Stored Product Pests do not travel far on their own; they rely on our life-style for transport in goods, cartons and packages.
They may however penetrate adjacent parts of a building through tiny apertures. Walls, floors and ceiling should have the smoothest possible surfaces which are impervious and without crevices.
Expansion and contraction joints should be filled with a material, which is expandable, and allows for movements.
Restriction of insects involves the careful selection and use of materials to provide smooth, impervious surface whenever possible, devoid of cracks and crevices where insects can hide, breed and feed. Covings at wall floor junction reduce the accumulation of debris and assist effective cleaning.
Tiled surfaces, which are not properly grouted, provide harborage for cockroaches, particularly where higher than average temperatures prevail. Leaks from roof, gutters, gullies or pipes, which are damp, encourage mould growth, which insects can feed on.
PEST CONTROLThe first line of defense against cockroaches is their restriction from entering into the premises by the implementation of good sanitation, construction, maintenance and exclusion program. Our company is a strong advocate for sanitation and removal of pest’s harborage sites in and around the premises.
The use of safe, environmental friendly and residual pesticides would be applied by our trained serviceman, having a working knowledge of pests’ behavior and control strategies. This involves finding the structural defects and other potential trouble spots that might need to be physically corrected by clients after proper chemical treatment. The selection of chemical preparations to be used depends mainly on the type of pests infestation encountered.
