Cockroaches have been the most unliked creature worldwide for over 3000 years. Why do we find cockroaches tough to kill?
First is how their body works. They have sensitive tentacles that catch the change in the air current and send signals to their central nervous system. The roach can turn and sprint away in split seconds. Moreover, they have flexible bodies so they can sneak in small places like cracks in the wall.
Second is their defense against pesticides. Roaches can produce detoxification enzymes and excrete them as poop. Furthermore, roaches populate hastily so they can earn resistance to a new pesticide within a month.
Though, there is one way to kill them. It is by nuclear weapons. Roaches do not have an immune system to radioactive. Besides, this will also jeopardize humanity, and because roaches are dependent on human waste they cannot survive.

Why do we fear cockroaches? How can we like them?
— Because they run so fast with their 6 legs. If they walk slowly and have some colorful designs on then maybe we will think it is a pretty creature.
