Types of Cockroaches Found in the Country
Currently, there are about 4,500 known species of cockroaches across the world. About one percent of these species are pests that frequent commercial and residential properties. In most cases, the cockroaches will enter into houses to escape the harsh weather conditions in their habitats or to look for food.

The color of cockroaches ranges from reddish-brown to black and the adults measure between one and five centimeters in length. The majority of them have wings but cannot fly for long distances. The insects have three pair of legs and a pair of antennae. Their body is generally oval in shape and flattened from the front to the back.
Provided they have enough food supply and ideal moisture, cockroaches can virtually thrive in any habitat. However, they regularly enter into houses looking for the damp and warm environments with abundant food supply. Some of the locations where cockroaches can exist in a house include greenhouses, basements, kitchens, bathrooms and any room with sewer pipes.
Normally, cockroaches are omnivorous scavengers. In their natural outdoor habitats, they feed on decaying plant and animal matter. Once inside the house, they can feed on virtually anything, including food remnants, fabrics, and soap, leather, toothpaste and pantry items. However, they are mainly attracted to the starch and sugary items in the house.
Basically, these insects survive for up to a year. The female cockroaches lay between 100 and 200 eggs. They undergo incomplete metamorphosis comprising of:
The females lay eggs, protected by a case known as ootheca. The eggs are laid in protected places within their habitat. However, some cockroach species carry their eggs until they are ready to hatch.
The incubation period for the eggs is between two and three months, after which nymphs emerge without wings. The nymphs go through various stages throughout their development, constantly molting to shed off their skin. Nymphs will molt about six to seven times before they reach adulthood.
The entire metamorphosis of cockroaches takes between four months and a year. The period taken by the insects to develop through the various stages is mainly affected by the humidity and temperature conditions.
