How to completely eliminate cockroaches

The cockroach is one of the four urban pests. Although its harm to people is not very obvious in daily life, when people see it, they always want to step on it to death, and even get goose bumps all over their body. And cockroaches exist in almost every household, especially in areas where there is a lot of food. So what can we do to completely eliminate cockroaches?

This cleaning cannot be an ordinary cleaning. The house must be spotless. No food must be exposed outside. Any tiny bit of food residue will attract cockroaches. So there are only two places where there are never cockroaches: military academy student dormitories and the meditation hall where nuns live. Since there is no food in these two places and they are cleaned meticulously, there are no cockroaches. When I was living in a military academy, the crazy and harsh military hygiene evaluation meant that even the deepest part under the beds was spotless, so there was naturally no basis for cockroaches to survive. As for the walls of the nunnery, they are clean and the women are diligent in cleaning, so there is no basis for cockroaches to survive. In addition, other places where people live have conditions for cockroaches to parasitize.

Here are my tips on how to kill cockroaches.

Remember, cockroach medicine can only treat the symptoms, not the root cause, and it pollutes the environment and can only occasionally have short-term or psychological effects. There are only two methods that really work, and this is the valuable experience I have gained over the past ten years.

1. Where there are rats, there will be fewer cockroaches, so if you hate cockroaches more than rats, you can try to introduce some rats. This is an interesting biological phenomenon that I occasionally discovered in my university dormitory. This dormitory used to be infested with cockroaches, running rampant until one day a mouse from next door came to visit and made its home in a shoe box under the bed, and the number of cockroaches dropped dramatically. Everyone was surprised by this rare positive image of the mouse. Of course, this is the lesser of two evils. Girls will probably drown me with their saliva, so I don’t recommend it.

2. The real killer is nature. What cockroaches are really afraid of is low temperatures. Below zero degrees, or even below 5 degrees, all cockroaches, from the cockroach mother to the cockroach eggs, will die.
