The pervasive cockroach has long become a national pain point. In various industries, the topic of cockroach extermination has always been high, but in the end of the heated discussion, it will be found that it seems that everyone is not the same species.
In fact, cockroaches are a common name, which generally refers to insects belonging to "cockroaches", and does not specifically refer to a certain kind. Due to the different regions of the north and south, the distribution of cockroaches is also different, so it has caused us to misunderstand.
In different places, the cockroach breeds we see are different, the cub once had a roommate who was a northerner, when she first saw the cockroaches in the south, she sighed from the heart: "The northern xiaoqiang is just scary, the southern cockroach is my life!" ”
Today, I will give you a pickpocket, what are the common varieties of cockroaches we have seen.
The most common cockroaches are the American sickle, the Australian cockroach and the short-winged cockroach, the small ones are the German sickle, the Japanese cockroach and the Asian cockroach, while the cockroaches in the tropics are generally larger.
<h1 class="pgc-h-arrow-right" data-track="7" > German cockroach</h1>
There are two kinds of cockroaches that are most common and widely distributed in China, namely the German cockroach and the American cockroach
Among the common cockroaches, the smallest is the German cockroach.
The German cockroach is widely distributed and is a worldwide hazard species, which is distributed throughout China. Because they cannot overwinter at room temperature, they are common in the homes of residents with heating facilities in the north of China, and they are the indoor dominant species in the northern region.
They are distributed in Heilongjiang, Inner Mongolia, Xinjiang and other places, in housing, restaurants, restaurants, hospitals and ships, trains, planes, etc. They have their presence, in short, only you can not imagine, there is no place where it can not be reached.
German cockroaches reproduce the fastest and are the most harmful, and German cockroaches have become resistant to certain cockroach drugs, which is the most difficult to eradicate among cockroaches.
<h1 class="pgc-h-arrow-right" data-track="7" > American cockroach</h1>
Because of the different climates, the American cockroach is the opposite of the German cockroach, and the American cockroach is the largest cockroach species in the cockroach family.
The American cockroach is an indoor dominant species in southern Guangdong, Guangxi, Hainan and Fujian, and is widely distributed in the south. It is mainly distributed in dark and humid environments such as sewers, heating ditches, toilets, bathrooms, breweries, sauce factories, etc.
Although the American cockroach has poor vision, it is very sensitive to vibrations and air currents, so it can often escape from human slippers with keen insight and superior speed.
Regarding how to control the American cockroach at the Five Star Hotel, the cub has previously published a detailed tweet, you can refer to it: self-report | How to control the Five-Star American Cockroach.
<h1 class="pgc-h-arrow-right" data-track="7" > black-breasted sickle</h1>
The black-breasted cockroach is distributed nationally, mainly subtropical species, but it is widely distributed in China, second only to the German cockroach and the American cockroach. It is the dominant species in the urban residential areas of Jiangsu, Zhejiang Jiangxi, Hubei and other provinces.
In the south, they are often mixed with American cockroaches and German cockroaches. Its living environment is similar to that of the German cockroach, mostly inhabiting the corners of kitchen cupboards, table drawers, etc., rarely in the wardrobe, and sometimes seen outdoors.
It is similar in size to the American cockroach, and can sometimes be lured indoors by light at night, but like the American cockroach, it is less capable of flying, and it can often be seen fluttering for some distance.
<h1 class="pgc-h-arrow-right" data-track="7" > Australian cockroach</h1>
Like the American giant sickle, the Australian cockroach has nothing to do with the name, they are all from Africa, but they have hitched a ride on a human and traveled to all over the world.
The Australian giant sickle needs a warmer environment than the American cockroach, so its distribution is limited. It is more common in the southern region of China, and has been recorded in Fujian, Guangdong, Guangxi, Sichuan and other provinces (regions) in China. In Fujian, their density peaks generally occur in the warmer months of June.
Their indoor habitats are similar to those of the American cockroach, and the two are sometimes mixed in kitchens and other places.
<h1 class="pgc-h-arrow-right" data-track="7" > brown-spotted cockroach</h1>
The main difference between the brown-spotted sickle and the American cockroach is the shape of the tail whiskers, the former being short and blunt at the end, and the latter being longer and the ends being very thin. In addition, the male brown-spotted cockroach has a short supraal plate, while the American cockroach grows up with a deep inmination in the center.
They are more dependent on a warm environment, in China, it is mainly distributed in the south, including Jiangxi, Fujian, Guangdong, Guangxi, Guizhou, and Yunnan, especially in Fujian Province, second only to the American cockroach in the composition of various cockroaches.
They will appear slightly later than other cockroaches. Even in the summer, it can inhabit the outdoors, such as dead tree trunks, under the bark, etc.
<h1 class="pgc-h-arrow-right" data-track="7" > Japanese cockroach</h1>
Japanese cockroaches are also small cockroach species, it is necessary to pay special attention to the fact that they climb fast and can fly, and people's fear of cockroaches mostly comes from their fast crawling speed and flying, and this species has this characteristic.
Fortunately, the distribution of the Japanese cockroach is narrow, and only Vladivostok in Japan, China and Russia has been documented so far. In China, cities such as Shenyang, Fushun, Anshan and Dalian in Liaoning Province are the advantages of housing. In recent years, it has also been found in Hubei, Guangxi and other provinces and regions.
They are mostly nocturnal and mostly come out at night. Cockroaches especially like to move in the gutters, kitchens, toilets and sewers in front of and behind the house, and enter the room through these passages, so the prevention and control of cockroaches must first check these places frequently, keep the room clean, leave no food debris, and attract cockroaches.
The above are the most common 6 species of cockroaches, no matter which one, there is absolute harm to human life, they carry a variety of bacteria and viruses, so once found to be eradicated!
