They can spread bacteria that causes diarrhea.


“Their presence is not only a nuisance, but they are also known to be capable of carrying the disease pathogen that could cause allergies, diarrhea, dysentery and even hepatitis B antigen.”

This little insect has existed from 400 million years ago even before the establishment of human civilization. Today, about 4,000 species of cockroaches have been identified; however, only a handful of these species inhabit human dwelling.

Common Hiding Places

Basically cockroach feeds on almost anything that is nutritious, including those fermented and rotten food. These cockroaches are commonly found in:

  • Sewers
  • Food-storage areas
  • Basements
  • Other hidden places

Common Cockroach Species

In Malaysia, the American (Periplaneta americana) and German (Blattella germanica) cockroaches are considered as important household and commercial pests. The female can lay about 10-60 eggs in each ootheca (egg case) depending on the species.

However, for the German cockroach, it will carry the ootheca for 24-48 hours before the eggs hatch and one week before hatching, the female will usually stop feeding. This behavior makes it even harder to be detected and controlled. Apart from that, condition with relatively high humidity and temperature will shorten the developmental time.


The presence of cockroaches is not only a nuisance but cockroaches are also known to be capable of carrying disease pathogen that could cause allergic, diarrhea, dysentery and even hepatitis B antigen.
