How to identify cockroach


Cockroaches have changed little during the 400 millions years they have been around. Most species are from the tropical or subtropical origin. They are not categories as social insects, they are gregarious or usually occur in large groups. They tend to feed on literally anything of nutritive value.

Cockroaches are amongst the most common pests for Residential and Commercial establishments. Their uninvited presence in our premises are a nuisance. Approximately 4,000 existing species of cockroaches in the entire world, only a few of these cockroach adapt and inhabit man’s dwellings.

The most commonly found are the American Cockroach, Brown-banded Cockroach and German Cockroach. By far, the most common infestation is the German Cockroach.

How to Identify a Cockroach?

Cockroach life cycle have simple metamorphosis: Egg, nymph and adult. Female reproductive system produces eggs ootheca or eggs capsules.

Each contains eggs arranged in parallel rows opposite each other. And may also contain as few as 4 to approximately 60 eggs depending on its species. However the German cockroach carries their eggs protruding on the back until 24-48 hours before hatching till the nymph emerges. Some other species retain the egg capsule, incubate it and give birth to their live baby Oriental cockroaches.

It is advisable to identify the type of house Cockroach species correctly. As Cockroaches vary in their food preferences and living habits. The American Cockroaches prefers living in habitat like food warehouses storage, basements or steam tunnels, and sewers. And prefers fermented foods, and enters via sewers or occasionally by human vessel migrations.

If the drains (sewers) and outside areas are inspected often. For American Cockroaches, or German Cockroaches infestation problem is reduced.

The mother adult roach usually carries its eggs cases which is oval-shaped until they hatch. Thus making this species difficult to eliminate. German roaches are the main culprit of infestations found in restaurants, cafes, and food outlets in Singapore. 90 percent of all Cockroach related suspension cases reported by the National Environment Agency are due to these roaches.

How to Identify American Cockroach?

Part of the Cockroaches are brown to reddish-brown colour and has light yellow edges on their shield or pronotum. In some countries, it is often mistaken for Wood Cockroaches or even Australian cockroach.

Both the male and female American Cockroaches can fly, which makes them more terrifying. The average lifespan of a Cockroach can be up to two years. That is how long cockroaches lives. And are more common in places where there are stocks of food such as bakeries, restaurants and grocery stores.

Roaches are commonly found on the ground. Homes with crawl spaces are more prone to roaches entering the house. They don’t hide their Cockroach eggs well enough and this allows Pest Control to zero in on their harbouring area.
