According to foreign media, bed bugs, which have been out of sight for many years, have recently become active again, and a bed bug crisis has broken out in many countries. According to relevant reports, bed bugs not only ravaged Britain, France and other European countries, but also “crossed the ocean” and spread to South Korea.
Bedbugs, also known as bedbugs, ticks, psyllids, mantis and so on, belong to Insecta, Hemiptera, bedbugs. Bedbugs have odor glands, which can secrete odor. They mainly play a role in defending natural enemies and promoting mating. They will leave a bad odor in the places where bedbugs crawl, so they are named bedbugs.
Jinan CDC has previously introduced that bed bugs often hide during the day, and their flat bodies can perch in tiny crevices, such as the crevices of mattress boards, cracks and seams of floors, cracks in walls and corners of sofa cabinets. Although bed bugs are called bedbugs, unless their bodies are crushed, there is no clear odor that can be captured by the human sense of smell, and it is impossible to judge the existence of bedbugs by the presence of odor in life.
“In fact, this is what people used to say about lice, people need not panic excessively, with the improvement of health conditions, it is now very rare in China.” Xia Yang, chief physician of colorectal oncology surgery at Beijing Shijitan Hospital affiliated to Capital Medical University, said that in theory, there may still be rural areas in China, but there are almost no big cities.
Xia Yang introduced that in the last century, many people used 66 powder (an organochlorine broad-spectrum insecticide, which has a very strong inhibitory effect on the synthesis of insect cholinesterase, and can cause insect disorders, spasm, paralysis and death) to kill bed bugs, which also caused many people to be poisoned.
“The most reliable way to prevent it is to do a good job of hygiene.” Xia Yang pointed out that people can use pesticides to eliminate these insects, including bed bugs, and they should also wash, dry or dry bedding regularly to prevent bed bugs.
According to reports, bed lice mainly feed on human blood. After being bitten by bed lice, local skin will be red and swollen, papules will appear, and severe pain and itching will affect people’s normal rest and work. In addition, the dropping of bed bugs contain allergens, which can cause Urticaria dermatitis in a small number of sensitive people, and pustules if further secondary infection occurs.
Xia Yang reminds, once be bitten by bedbug carelessly, can use soapy water to rinse, daub compound calamine lotion to wait to stop urticant; If the skin appears damaged, can use antibiotic ointment; If be bitten more serious, answer to go to a hospital in time, ask to use antihistamine medicine reasonably according to the doctor.
Jinan CDC reminds us that once bed lice are found in life, we should pay attention to the following aspects.
Check the environment: repair or fill the wall cracks, bed board cracks, floor and other gaps to reduce the habitat of bedbugs, so that they are difficult to hide or have nowhere to hide. At the same time, bedbugs are killed by combining physical and chemical methods.
Physical deworming: Use a high-power vacuum cleaner to suck out the bugs hiding in the crevices; use high temperature, such as the high temperature steam generated by the hanging ironing machine to treat the folds of the mattress, which can effectively kill the bugs inhabiting in it. Contaminated sheets and quilts can be washed with hot water above 65 C, and items that are inconvenient to clean need to be exposed to the sun.
Chemical control: The insecticides used to control bed bugs are mainly pyrethroid insecticides. Imidacloprid and dinotefuran are also effective in killing bed bugs.
Personal protection: Infested residents can reduce the probability of bed louse bites by applying repellents such as DEET and mosquito repellent ester.
Seek help: Consult disease prevention and control institutions at all levels, or seek help from pest control companies.
