The old lady, accompanied by her sons, came to the hospital for treatment because there were many itchy red bumps on her arms, legs and trunk, and she complained that black bugs were found on the bed at home. When I showed the photo of the bed bug, the old lady told me for sure that it was it, it was it, it was it, our enemy was it!

Hmm, "Little Nezha" came out, and it turned out to be an unlucky bug! It turned out that the old lady's home was being renovated, and the moving company moved it to the newly rented house. Then the problem arises. There are two possible ways: there are a large number of bed bugs in the newly rented house. It cannot be ruled out that the old tenant moved because of the unbearable itching, leaving behind bed bugs that cannot be driven away; or the moving company's Some bed bugs were left in the large truck when it was moved to a home where bed bugs gathered. As a result, these bed bugs found new settlements and began to feed on blood.

The old lady’s youngest son said: Mom, you sleep in my room tonight, and I’ll sleep in your room to see what bites you. I’m not afraid! I admire my son's filial piety, but bugs don't admire me. They just sigh: Another delicious food has arrived!

It can be seen that the transmission characteristics of bed bugs are:

1. Bed bugs can stay in a certain family for a long time. The clusters live by sucking blood. They can live for a long time without eating or drinking. Time;

2. Bed bugs mostly hide in bed boards, but can also hide in clothes, bedding, mattresses, suitcases, etc., and can be carried around the world with moving or traveling;

3. Bedbugs are difficult to kill. They bite people and suck their blood. They itch very badly. There is only the blood of nutritional supplements in their eyes. There are no men, women, or children, no sense of shame, and they simply don’t recognize their relatives!

4. Killing bed bugs is indeed very time-consuming and laborious.

So how to effectively kill bed bugs? After summarizing, I think we need to pay attention to the following points:

1. Since bed bugs live in clusters, finding one bed bug in the home means that there must be n number of bed bugs in the home, so the net must be cast widely and all efforts must be concentrated to eliminate bed bugs. ;

2. If you pick up other people’s discarded old furniture, such as old sofas, old mattresses, old trolley cases, etc., they must be carefully washed and scalded. In addition to killing bacteria and other microorganisms, you must also Get rid of bed bugs and eggs;

3. Once you find bed bugs in your living environment, start killing them!

4. Eliminate all visible bed bugs: Continuously beat the bed boards, bedding, clothes, sofas, etc. to expose the bed bugs during the hiding period, and then trample, beat or crush them to death with all available tools. Solutions;

5. Boiled water and sun exposure: Use boiling water to water the gaps between bed boards and furniture to kill bed bugs, scald clothes and bedding in boiling water or soak them in laundry detergent for a long time, etc. It can quickly kill bed bugs and eggs; in summer, bed boards, clothes, etc. can be exposed to the sun to kill bed bugs or induce bed bugs to crawl out and eliminate them;

6. Insecticides to eliminate bed bugs: Commonly used insecticides All are basically effective, and insecticides containing deltamethrin, cypermethrin, etc. can be used. Kesulin (deltamethrin) is currently commercially available. Note: Kesulin also has the advantages of high efficiency and long-lasting effectiveness in killing cockroaches, mosquitoes, flies and other sanitary pests. In addition, some insecticides that kill cockroaches can also be used to kill bed bugs;

7. Pesticide by professional institutions: If you can’t handle it yourself, you can ask for help from professional institutions, such as the Beijing Pest Control Association, Tel. 87269001, or you can consult the Beijing Public Health Hotline: 12320.

8. Let me say something irresponsible: If you really have nothing to do, just "leave home", don't want anything, take nothing with you, and buy clothes, furniture and other daily necessities again after moving. But in this case, the loss would be a bit too great~~~

9. Finally, I would like to thank the deputy director of the Beijing Center for Disease Control and Prevention @Zeng Xiaopeng. Some of my opinions come from Director Zeng’s article.

10. Bed bug bites can be very harmful, so collective action is needed to eliminate bed bugs!
