There are fleas at home. ..

1. What are the hazards of fleas?

There are six kinds of common fleas, such as human fleas, cat's Chlamys, Indian guest fleas, diseased fleas, fleas of different sizes and leptospira tarda. In addition, there are bearded fleas, fleas with axe covers and square squirrels in Songjiang.

Direct harm: ① Fleas can suck blood for both sexes, with high frequency and large blood volume. Harassment and stimulation often make people and animals fidget. When sucking blood, saliva is injected into the subcutaneous tissue of the host, which can cause local allergic reactions, local papules and rubella, which can become wind masses after scratching, and purulent infection after scratching. ② Parasitism: Some fleas can still cause parasitism and anemia of domestic animals.

Indirect harm: Plague is a severe infectious disease caused by Yersinia pestis. It spreads among mice by fleas. As humans or domestic rodents enter the focus of infection, they are introduced into villages and cities, causing plague epidemic and extremely serious harm.

Second, how to prevent fleas?

(1) Control method: The reproduction and survival of fleas need suitable breeding conditions and sufficient blood sources, mainly in dark and humid places where animals live. The fundamental measures to control fleas are to improve hygiene, improve the environment, control and eliminate breeding conditions, carry out rodent control, and strengthen the management and personal protection of domestic animals such as cats and dogs.

(2) Chemical flea control method: spray insecticide on the ground, under the bed, at the foot of the wall, under the cupboard and near the rat hole, and in the habitat of livestock, and close the door 1 ~ 2 hours after application, which can achieve good results.

To deal with fleas, we must first understand the life history and habits of fleas in order to get twice the result with half the effort. Generally speaking, a flea's life experiences-> eggs; Larvae->; Pupa)-> Adult, a typical complete transformation. From the hatching of eggs, it takes about 17~2 1 day for most kinds of fleas to develop into adults. However, the biggest headache is in the pupa stage! If the environment is not so suitable, fleas can stay for more than a few months in the pupal stage, and their endurance is comparable to that of cicadas. Therefore, once fleas are found at home, we must be psychologically prepared for a long-term war of resistance, so that we will not be carried away by a temporary victory and fall short.

Next, let's talk about the habits and needs of fleas. Basically, no matter at that time, the tolerance of fleas to humidity is much lower than that of temperature. In other words, it can survive in spring, summer, autumn and winter. However, intolerance to dryness is fatal! In addition, fleas like to hide in the dark, which is a shameful habit. It can be simply speculated that both eggs and larvae, except you, me or cats and dogs, are bound to hide in wet places such as carpets and corners …! Cleaning or drugging these key places can easily solve the flea problem at home. But remember, it needs to be cleaned up many times, and the interval between each time should not exceed 3 weeks (that is, the life cycle of 2 1 day) to achieve the effect. It would be better if the neighbors could also come.

As for how to kill fleas and reduce the poison to the environment? Here, the author only provides a more natural method, that is "clear water"! Yes, don't doubt it Because insects breathe through the trachea, people who forget can go back and look through junior high school biology textbooks! As long as the tiny trachea meets water, it will be blocked by capillary phenomenon, causing suffocation and death. In short, it is drowning! Of course, the effect of using water alone is not very ideal. Because insects also secrete oil to protect themselves. At this time, as long as a small amount of salad dressing, washing powder, etc. In order to wash off the oil on the surface of insects and destroy their surface tension, the insecticidal effect can be easily achieved! This trick is effective not only for fleas, but also for all insects! There are people suffering from pests in our garden, so we might as well use this trick to deal with them. A friend once studied at Sun Yat-sen University. Because someone kept a dog in the dormitory, the whole building was full of fleas! Finally, at the suggestion of dermatologists, the floors, walkways and corners of all bedrooms in the whole building were thoroughly cleaned with fire water, which solved the problem. Of course, plus cleaning the wardrobe and cleaning all dirty old clothes, the effect will be better! Finally, in the corner … and other damp places on weekdays, put some quicklime to dry and kill fleas, which can reach the point of extinction. As for other flea killing drugs, they are sold in the market or veterinary hospitals, and they are introduced, so I won't explain them here.

Go out for a month, fleas will never starve to death.

The most important thing is that the humidity in your home is too high, that is, it is too humid to adapt to the growth and reproduction of fleas.
