Why is this building often seen "Xiao Qiang" who can't die?

I believe that many Zhengzhou citizens will believe that there are no cockroaches in Zhengzhou, and these annoying and difficult to eliminate "small strong" will only appear in southern cities. However, in a small area in the northern section of Zhengzhou Wenhua Road, many owners are worried about the endless number of cockroaches.

Where do these cockroaches come from? What are the dangers? And how to prevent it?

Where did the 32-storey residential building cockroach come from?

A number of owners of the community told the Dahe Newspaper dahe client reporter that there are cockroaches on the 1st floor to the 32nd floor of building 2 of the community, and almost every owner can see it more or less in his home, and there are hundreds of them in the home, even during the day.

On the morning of September 22, the reporter learned through a number of owners of Building 2 that because it was really difficult to bear the troubles caused by cockroaches, they had hired a professional pest control company to kill them a few days ago, and the effect was prominent in the past few days.

So, what species are these cockroaches? Where did it come from? The reporter then contacted a staff member who had dewormed the residential building.

According to him, more than 95% of the cockroaches in the community are German cockroaches, and about 5% are black-breasted cockroaches and American cockroaches, all of which belong to invasive species, not domestic cockroaches. "These 'little strong' are likely to enter the resident's home with a courier package or other thing to breed, and then invade another resident's home through the pipeline." 100% of foreign species cockroaches are brought back from outside and cannot be bred at home for no reason. ”

Why do these cockroaches "love" the residential buildings of the community?

During the interview, the reporter learned that cockroaches had appeared in Building 2 and Building 5 of the community a few years ago, and they were repeatedly eliminated. A staff member of the property in the community said that they had also contacted a professional pest control company to kill and spray cockroach extermination agents in the corridor every three or five minutes, but the effect was not very good.

So why do these foreign cockroaches "love" the residential buildings in the neighborhood?

According to the staff of the insect removal company, after some owners of the community have done cockroach removal, some cockroaches may run along the pipeline to other homes, so as to continue to breed. "There are many owners who put shoe cabinets in the corridor of the doorway, and it is difficult to spray cockroaches in the dead corners behind them, which may also be one of the reasons for the continuous cockroaches in the corridors."

What are the hazards of german cockroaches? How to prevent it?

According to Manager Zhang of a pest control center in Zhengzhou, the German cockroach is the most widely distributed and the most difficult to treat. Because it appeared in Zhengzhou very early, and the number far exceeds that of "domestic production", the insecticidal circle has defaulted to it as a local cockroach, and more than 90% of the cockroaches they encounter for extinction are German cockroaches.

In addition to stealing food, contaminating food, damaging clothes, books, destroying computers and other sophisticated instruments, the main harm of German cockroaches is the spread of disease. Because they are adaptable, reproduce quickly, and are prone to resistance to chemical pesticides, it is very difficult to control.

Manager Zhang said that to prevent the flooding of German cockroaches, the most important thing is to maintain environmental hygiene in the home, clean the toilet and sewer in time, clean up the garbage, leave no sanitary dead ends in the home, followed by early detection and early killing.
