No hard throw with slippers, no pesticide: why are cockroaches so hard to kill?

So far, let alone pesticides. Proven resistance to 43 different chemicals Neither a roughly thrown slipper nor various medications will work against cockroaches.

The curious point is that cockroaches, How can they be so resilient to this?

There are approximately 5,000 different species of cockroaches.

Cockroach

99% of them; by recycling the dead, breaking down organic matter or feeding other animals They play an important ecological role and live in different environments.

But about 25-30 species, They have adapted to living around peopleir. German and American cockroaches are the leaders among these species. Furthermore, these creatures owe their resilience to their physical and chemical adaptations.

They are disturbingly stubborn when it comes to conventional methods of destruction.

Cockroach

According to research, these are, for example, the bodies of American cockroaches Even feels a light breeze and they very quickly send this feeling as a signal to the central nervous system.

cockroaches, are among the fastest invertebrates ever. and can reach speeds of 50 body lengths per second. Their speed is equivalent to that of a human running more than 300 kilometers per hour.

With their flat and flexible bodies, they fit into spaces smaller than a quarter of their height.

Cockroach

Even when we hit them, we distribute the blow across their bodies, They can withstand pressure up to 900 times their weight. The endurance of cockroaches is not limited to this.

Them; They can eat a variety of organic materials such as hair, dead skin cells, glue and paper, and this They have a large and strong digestive system is the indicator. Again, these creatures can even consume rotting food that contains small amounts of nitrogen, the main component of DNA and proteins.

It is also very difficult for cockroaches to get sick.

Cockroach

Because they are genes that allow them to become immune to various pathogens has. These genes are often copied many times and when infected, many antimicrobial molecules are released.

Cockroach

It is almost impossible to kill cockroaches with insecticides. They produce detoxification enzymes, which render pesticides harmless. In other words, these creatures, faced with a deadly drug, It removes the poison from his body as waste and They continue on their way.
