Why is there a "small strong who can't be killed" everywhere?
Strong survivability
Cockroaches are one of the oldest pests, having been rampant on the earth 320 million years ago. 65 million years ago, probably after a major catastrophe like an asteroid hitting Earth, the dinosaurs that once ruled the Earth quickly became extinct. Other creatures were also hit hard, and the earth was silent.
However, cockroaches are still living tenaciously, looking around for food to eat. According to cockroach fossils more than 100 million years ago, there is little difference in appearance between cockroaches at that time and today's cockroaches. With the vicissitudes of the earth, many insects have become extinct in those disasters, and it is absolutely a miracle that cockroaches can multiply to this day.
Cockroach fossils indicate that cockroaches are a very ancient animal
Cockroaches are widely distributed and are spreading to other regions because they can lurk in human utensils and follow people to the ends of the earth, and cockroaches from countries such as the United States, Australia and Germany have been found on the continent.

Moreover, Why are cockroaches so good at escaping? This has a lot to do with their anatomy. The nerve endings on the leg joints of cockroaches are very sensitive, and the slightest footsteps can be felt. Cockroaches also have complex vibration receptors on their tails, which can sense the direction of the source of the vibration in order to escape in the opposite direction. Cockroaches have many short hairs on the side of their mouths, which can not only judge the taste of food, but also the taste of poison bait to avoid being harmed by poison.
Dare to eat anything
Cockroaches have a particularly good appetite, they dare to eat almost anything, fragrant, smelly, hard, soft can enter their big belly.
Cockroaches are nocturnal pests like mosquitoes, they like to choose warm, humid, food-rich and multi-gap places, therefore, kitchens, bathrooms, wardrobes, door frame seams, radiators, appliances, cardboard boxes, cockroaches can be found everywhere. At night, they come out in search of food.
They not only eat leftovers, leftovers, vegetables and other foods, but also eat feces, sputum, small animal carcasses and other dirty things, people eat the leftovers, leftovers or vegetables stained by cockroaches will get sick, cockroach-borne diseases include typhoid fever, hepatitis, tuberculosis, allergic asthma and dysentery.
Fight cockroaches
In fact, "Xiaoqiang who can't be killed" also has opponents. The natural enemies of cockroaches are spiders, scorpions, centipedes, ants, toads, lizards, geckos, etc. A bird called Cucarachero (scientific name Troglodytes audax) also preys on cockroaches. In addition, cats, monkeys and mice also prey on cockroaches and are natural enemies of cockroaches. At present, biological extermination is the most effective. But if you can't do biological pesticide at home, then it's good to look at the method below.
The war between humans and cockroaches is going on. To deal with cockroaches, you should first pay attention to the environmental hygiene of the home. We all know that whoever has the dirtiest kitchen has more cockroaches.
Usually, we have to seal the leftovers, leftovers and vegetables with plastic wrap, dump all kinds of household garbage in time, and clean the stove and sink in time after cooking, so that cockroaches will escape because they can't find food. All kinds of kitchen utensils and hidden corners of the home should be cleaned regularly so that cockroaches have no hiding place and reduce their breeding opportunities.
In addition, we should also pay special attention to preventing cockroaches when decorating, choose materials without cracks, and repair furniture and walls in time if they are cracked, so that cockroaches have no place to hide and lay eggs. When decorating, close all sewer pipes to prevent cockroaches from climbing up the pipes from the sewers.
