Cockroaches are insects.  The German Cockroach is one of our more common pests!  Houses, apartments, or living quarters of any kind can be infested with them.  They can even be carried home from the grocery store.  While there are approximately 4600 species, only about four of those are well known to us as “pests”.  They are, for the most part, nocturnal, and when you turn the light on at night, they will and hide to get away from any light source.  In some parts of the world, especially Asia, that is not the case.  It is an interesting fact that humans have been inspired to use their structure for, of all things, “robotic legs”.

Cockroaches are not too particular as to what they eat.  They have been on earth for millions of years, and, believe it or not, their vitamins come from the bacteria living in their own bodies.   They appear to like to be touched, hence, perhaps, their social ability?  They can sense air movement, are fast, and hard to catch.  They would also survive a nuclear bomb because of their ability to hide in small crevices and their inherent tolerance to radiation!  Those close to the blast might not survive due to the intense heat.

They also carry bacteria that are detrimental to our health.  But, in the grand scheme of things, they do have a purpose in the food chain.  They eat insects and are eaten by other predators, such as birds. 

They are not popular in our homes, but outside In the natural environment, they are invaluable and an important addition to the world of insects, as well as, in the laboratories.
