Although there are, in fact, over 4,000 different species of cockroaches, it may come as a surprise to learn that only 40 species are considered pests, the remainder are regarded as beneficial to the environment.

In the Philippines, the German cockroach and the American cockroach are commonly found. These species are a nuisance because they infest homes, businesses and other structures and they are able to spread diseases and cause other health issues. Most indoor roach infestations are treated in the same manner and with the same cockroach control products, regardless of the species.

Cockroaches are most active during the night, preferring to stay hidden in cracks and crevices during the day. They are attracted to food available in your property and will feed on nearly anything from food crumbs to animal droppings.

As with all effective pest control, it is preferable to locate the source of the pest infestation and then eradicate it. In so doing, we not only deal with the existing infestation but also introduce a process that will help prevent future reoccurrences.

Apart from actually seeing cockroaches, the following are signs that you have a cockroach infestation and can help you pin-point their nest:

- black grainy droppings can be found in the cabinets and along the walls or routes that they travelled on.

Smear marks - where water is abundant, brown and irregular-shaped smear marks will appear on horizontal surfaces and wall floor junctions.

Molted skin - evidence of brownish skins can be found close to where they are breeding, as immature cockroaches shed skin about 5-8 times when they mature to adult.

Egg cases - appear as small dark brown oval-shaped casings.

Damage - look for signs of damage on food packaging and organic goods, including leather and books.

Unpleasant odour - a distinctive musty smell when cockroaches are present in large numbers.

DBMPC has developed a cockroach control programme that combines a rigorous source eradication programme with a combination of chemical spray and professional grade gel bait. This programme has proven to be highly effective in the control and elimination of cockroaches, both inside and outside the property.

Whilst the chemicals and baits employed are similar, the method of application will vary depending on the species of cockroach encountered, the level of infestation, and the type of property to be treated.
