Why do Cockroaches Find Homes To Be A Suitable Place to Live?

The following are some of the reasons as to why cockroaches are able to endure in human environment:

Abundant Food Sources

Our homes and businesses provide them with everything they need such as food, water and shelter. They’re not picky eaters.

Other foods that the cockroach can take includes, crumbs, cardboards and glue among others.
Low-income apartments may have restricted ways of disposing of waste products. This attracts more cockroaches.
Cockroaches are found in households that are located inside cities and towns as revealed by the survey results which indicate that up to 38% of the households are always likely to encounter the pests on a regular basis.

Warmth and Moisture Attract Cockroaches

Cockroaches are warm and humid-loving insects. Most homes and companies provide just that.

Kitchens, bathrooms and basements are the most favorable environments.
The german cockroaches (Blattella germanica) are found in cracks and crevices as well as appliances.
The Periplaneta americana or American cockroach cockroaches mostly infest areas with warmth such as drains and basements.

These are some of the conditions that facilitate growth of these pests, especially the roaches as they reproduce very fast. The German cockroach can lay eggs which are 40 in number therefore has the potential of a rapid global spread.

How Cockroaches Adapt

These creatures are so flexible that they can survive in any condition that they can possibly come across. They are found in every part of the world, from the hot rain forests, to city apartments. Moreover, their flexibility promotes them to adapt even in the case of their feeding habits as well.

They can survive on:

Carbohydrates particularly starches and sugars which are the preferred diets.
Any kind of organic material when food is scarce

In addition to that, Cockroaches have the ability to build up a resistance to many of the pesticides used in control hence making it very difficult to deal with the pests. Due to their adaptability, they are described as “resilient insects. ”

Global Spread Through Human Activity

Cockroaches are one of those insects that have benefited from human influences in their distribution all over the world. They hitch rides on goods and vehicles that people transport through global travel and shipping.

For example…

It is thought that the Oriental cockroach has come to different areas through the movement of goods and services. Therefore human activities have led to the expansion of the habitats of these cockroaches in areas that are far from their original natural habitats.

It’s a global problem that has affected the poor and rich.
