I have lived in a rented house in Beijing for five years and have been living well. 2065438+August 2006, my husband and I went to bed one after another, which was very strange.

(1) physical control 1. Manual capture: beating bedstead, bed board, kang mat, straw mat, etc. It is necessary to shake out the bedbugs and kill them, or use needles and threads to pick out the bedbugs in the cracks and kill them. 2. scalding with boiling water: bedbugs are not resistant to high temperature, and eggs and adults can be scalded with boiling water. The bedstead, bedplate and other appliances with bedbugs can be moved outdoors, the spout filled with boiling water is aimed at the gap, and the bed bugs and their eggs are scalded by moving slowly, so that the gap reaches high temperature. Clothes and mosquito nets with bedbugs can be soaked in boiling water. 3. Exposure: For clothes that can't be scalded with boiling water, it can be exposed to strong sunlight for 1 ~ 4 hours and turned over, so that bedbugs are exposed to high temperature or crawled out to kill them. 4. Prevent the spread of bedbugs: In the living room where bedbugs are active, it is necessary to strictly check and handle the migration (relocation or transaction) of luggage, furniture and other items to prevent bedbugs from being brought out and brought in to cause spread;

(2) Chemical pesticides used to control bedbugs in the past, such as 223, 666, trichlorfon and dichlorvos. Due to the discontinuation of 223 and 666, the efficacy of dichlorvos and trichlorfon is short-lived. These organochlorine and organophosphorus pesticides are easy to make the brown shed brittle and broken, which is not only unacceptable to the public, but also difficult to achieve the goal of eliminating bedbugs. Therefore, these drugs are no longer used for bed bug control. Fenthion is the best drug to kill bedbugs in recent years, and its characteristics are as follows: ① high efficiency: it can be basically eliminated after one treatment. (2) Long duration: once applied, the drug effect can last for several months, so it can not only kill adults and nymphs in the environment, but also kill nymphs newly hatched from eggs after treatment and bedbugs newly invaded from the outside. ③ Easy to use: You don't need spraying tools, just dip the old brush into the liquid medicine and brush the gap yourself. 4 Low cost: it costs about 10 cents to handle a household. ⑤ Safer: The toxicity of fenthion is three times less than that of dichlorvos, and the seam coating method is not easy to be touched. When in use, 50% fenthion concentrated emulsion is diluted by 50 times with water to form milky white 1% fenthion liquid medicine, which is dipped with a brush and smeared on the gap with bedbugs. The dosage of each single bed is 50 ml, and Q should be applied to the gap with bedbugs. Serious violations, indoor furniture, doors and windows, mirror lines, treads and other gaps need comprehensive treatment. Hotels, bathrooms, dormitories, etc. As long as you find a place, the beds and things in the same room need to be handled with all your strength. Wipe off the dust before applying the medicine to prevent the medicine from losing with the ash. Let it dry for several hours after application. Spraying method is not suitable for controlling bedbugs, which not only has poor effect, but also makes drugs splash, which is not only a waste of liquid medicine but also unsafe. It is advisable to apply medicine on sunny days and dry clothes and quilts at the same time. It is best for a unit (or a Committee) to act in unison. On the basis of insect investigation, do everything possible. Except for fenthion, phoxim and chlorpyrifos have similar efficacy in killing bedbugs, and their application methods and techniques are the same as those of fenthion.
