30 Mind-Blowing Facts About Cockroaches


Cockroaches are by far the most disgusting creatures. Personally, I have developed what Psychologists call as Katsaridaphobia because of unfortunate cockroach encounters. I’m sure that some of you have heard of the term. Katsaridaphobia is the fear of cockroaches. So, what is the big deal? Phobia is more extreme than fear. When we are afraid, it is normal for us to sweat, scream, run, and palpitate.  But if a person acquires the psychological disorder phobia, he will experience more than just these symptoms.

He or she is more likely to experience panic attacks by just the mere thought of the object of fear. When a person has a phobia, he or she is more likely to become dysfunctional in life. For example, when I had Katsaridaphobia, I did not want to enter the bathroom or the kitchen upon the anticipation that there are cockroaches lurking around. Even if I really wanted to pee, I would call for my mom to make sure that there are no cockroaches in the comfort room. Imagine the discomfort that my condition brought me.

  • Cockroaches can survive anything, even a nuclear explosion. They will eat literally anything just to survive – from fruits to meat, to debris, even the carcass of other animals just to live.

  • Cockroaches can live for another week without their heads. To some of you who cut cockroach heads for elimination, it does not work as much as you know. They can still walk around and spread diseases for another week. The difference is, they are directionless without their head. Who knows where they can go without a sense of sight and fear. 
  • Many ask, how can cockroaches live for days without a head and other pests can’t? Well, after their heads have been cut off, clotting will seal off their neck to prevent blood loss. Their head is not responsible for respiration. So, they’ll be good for a while before they die of hunger.

These creatures are cold-blooded animals. Their body temperature depends on the environment. If their surroundings get too cold, their bodies won’t be able to take it. However, there are some species that can ward off the cold. The Japanese cockroach can withstand a temperature as low as-8 degree Celsius. If its body freezes, it can unfreeze itself when the temperature gets warmer.
