Summer is the season of flea flooding. Why do fleas suddenly occur in the community? Today, the reporter interviewed the relevant personnel of Wuhan CDC. According to them, fleas in the city generally come from stray cats, dogs and mice. From May to August every year, it is a high incidence period of fleas. A female flea can lay eggs up to 400 to 500 or so, which is easy to break out in large numbers without timely control. Flea will die automatically within a week after leaving the host (the body of the dog and cat), and killing it is not complicated.
When residents find a large number of fleas, they should ask a professional insecticidal company. On the one hand, they should investigate the source of fleas to avoid the expansion of flea range. On the other hand, they should spray special drugs to kill fleas in the public space of the building. The principle is to start from the first floor, layer by layer, door seam, wall below 1 meter and other parts, which are the main activity areas of fleas, and to focus on prevention and control.
I can tell you my personal experience last year. The house I rented last year was full of fleas and itched to death. Share my killing methods. The first method is to arrange the clothes first, connect the big bucket with water, put the washing powder and soap into it, and then put all the clothes in the bucket and soak them for 3 hours. You should know that fleas are not water-based, and two hours is enough to kill the clothes and quilts, but don't forget that there are still insect eggs, which are very difficult to eliminate. If the clothes and quilts can be cleaned, soak them for two hours before they can be cleaned Wash and dry the quilt.
The second method is to put on the mask and gloves, open the quanjingling potion, and mix the water 20-50 times according to the instructions of quanjingling. If the flea is serious, the dosage can be increased. First, clean up the things on the bed, then turn over the bed board, take out the formwork, and expose the bed beam. If the four beams in the middle need to be removed, the intersection is Flea spawning place of traditional Chinese medicine, and then began to prepare a watering can.
The third method is to spray carefully. It must be operated in accordance with the instructions. Spray to make the board flow. Spray more if you find any black spots, especially at the junction of the bed board and the bedstead, as well as the cutting surface of the bed board. Fleas are hidden in it, but they can't be seen in the daytime and come out at night.
The fourth method is to spray the bed board in reverse after spraying. Next, check the wall and ceiling. Remember that all the small black spots on the wall are the concentrated places of fleas. Those black spots are the places where fleas usually eat enough to go to the toilet. There will be a lot of insect eggs, which can't be let go. There are nail holes at the junction of the electric light and the wall on the ceiling. If possible, fill the gap of the wall in time to reduce the gap.
The fifth method is that the walls and bed boards are all cleaned, and the next step is the clothes. When cleaning the clothes, remember to add salt. A small amount of salt can be put in to kill the flea eggs. After cleaning, put it in the sun to prevent the remaining flea eggs. Refer to the picture above the manual to check whether there are fleas. After killing, close the doors and windows for two hours, and then ventilate for half an hour. Children and pregnant women shall not be present at the site of application.
