How to treat flea flooding in a residential area in Beijing? How is it caused? How to prevent fleas?

What a surprise! People are getting strange. Fleas are biting again! A recent news report said that residents in Block C of Rongzunbao Community in Chaoyang District, Beijing are suffering from fleas.

In order to deal with these fleas, residents tried their best to use pesticides and traps, and invited professional disinfection teams to their homes for disinfection. The host must clean up the fleas before going home every day before he dares to enter the house. Even so, many fleas were brought into the house.

Then the question is, why are there fleas flooding today when the sanitary level has been greatly improved? Where do the fleas in the underground garage of the community come from? How should people prevent fleas? Let's analyze these problems together.

Flea is a completely abnormal winged insect, mainly distributed in warm and humid areas. It used to be common in southern China, and there are many places with suitable climate in northern China.

There are more than 2500 kinds of fleas in the world, and their morphology, ecology and life history are very similar. Common fleas are cat fleas, dog fleas, human fleas and rat fleas. You can tell from their names what their main hosts are.

Fleas are between1.5 3.3 mm in length, and it is difficult to find them hidden in the hair of the host. They have sharp mouthparts, broad bellies, no necks and smooth bodies. These characteristics are simply born for blood sucking, and they are easily parasitic on the hair of mammals or the roots of bird feathers.

The best thing about fleas is their jumping ability. Their hind legs are very developed, and they can jump 350 times as long, which is equivalent to a person jumping over a football field.

Fleas are also tenacious. Their hard shells can bear 90 times their weight. If human beings have a shell as strong as fleas, even if they fall to the hard ground from a height of 1000 meters, they will be safe and sound.

Fleas like to live in dark and humid places, such as the community garage mentioned at the beginning of the article, which is very suitable for the breeding and spread of fleas. However, fleas require higher ambient temperature, and the environment around 18 20 is the most suitable. Too high or too low temperature will affect their reproduction.

The reason why fleas can quickly climb on the owners of the community is that they can quickly find the host besides their strong jumping ability. Fleas can find their hosts through heat sources, and both adult fleas and newly hatched larvae can find their hosts along the direction in which animals release heat. So when the owner passes the garage, fleas can quickly find and jump on the owner.

The harm of fleas to human beings is mainly reflected in two aspects. First, the place where people bite and suck blood is extremely itchy, which seriously affects people's normal life and rest; Second, fleas jumping from animals are likely to bring a lot of bacteria and even plague to human beings.

Fleas can spread many important infectious diseases, including taeniasis, plague, hemorrhagic fever with renal syndrome, Bartonella disease and so on. If a flea invades your home, you must kill it in time.

According to related news reports, the fleas in the underground garage in Chaoyang District of Beijing are probably brought by wild cats. Because of the cold weather recently, many wild cats come to the underground garage to keep out the cold. Some cat lovers often throw some cat food in the garage, and these stray cats are reluctant to leave.

It happens that the underground garage environment is dark and humid, and the temperature is not particularly low, which is very suitable for flea breeding. Wild cats covered with fleas waited for a long time in one place, where fleas took root and spread.

Friends who have owned cats may know that it is necessary to deworm cats regularly. This kind of insect repellent can be divided into external drive and internal drive. Internal drive is to kill Toxoplasma gondii or ascaris in cats, and external drive is to kill fleas.

Domestic cats are still vulnerable to fleas, especially wild cats. They have been catching mice in every corner of the city for a long time, and they are easily parasitized by rats or fleas in the corner of the city. Wild cats are not rejected by them.

In general, wild cats are scattered and will not cause a large number of fleas in a certain area. However, the underground garage in this community is not only warm, but also specially fed by people, so a large number of wild cats are gathered here, and fleas are spreading among wild cats, and the number and scale are increasing.

In short, these fleas in the garage of the community are probably brought by gathered wild cats. The gathering of wild cats is related to the cold weather and the feeding of cat lovers.

Since fleas are very painful and know the source of their spread, how to prevent them?

First of all, the fleas in the underground garage must be killed by chemical means, and chemical agents should be sprayed in every corner of the garage. In addition, it is necessary to solve the source problem of fleas, that is, to control wild cats. The residential property introduced in this article has bought a cat cage and handed over the caught wild cats to the rescue station.

Secondly, in terms of personal prevention and control, before the fleas in the community garage are completely extinct, go to the underground garage to minimize barefoot and legs and wear pants. Before you go home, you must clean your body in all directions to avoid bringing fleas into the house.

Third, killing houses in an all-round way, fleas have very strong reproductive ability and survival ability. They can live without eating anything 12 months. If they are not completely eliminated, the house will soon be invaded by fleas.

The fourth is to keep the house clean and tidy, especially in the corners where the kitchen, bathroom and bedroom have not been disturbed for a long time, and pay more attention to hygiene in daily life.

Finally, if you are bitten by a flea, you can apply toilet water, wind oil and so on. It can play a very good disinfection and itching relief effect. If you have pets at home, it is necessary to clean your body regularly and repel insects.

Although the sanitation of people's lives has been greatly improved, and the common fleas and bedbugs in the past have also been greatly reduced, these pests have not completely disappeared. Once they have a suitable living environment, they may make a comeback.

It is not the only case that the garage in Chaoyang District of Beijing was invaded by fleas. Many communities in China are infested with fleas because of the gathering of wild cats.

Finally, I have to remind everyone that when rescuing some wild cats and dogs, we should consider the problem as comprehensively as possible, contact the relevant rescue centers or make a good choice. If you just feed food, it is likely to have other negative effects.

Mainly wild cats and wild dogs, because they don't take a bath for a long time and sometimes play in the grass, so there are many fleas on the lawn. The lawn in the community should be disinfected, otherwise the children will be itchy and uncomfortable to play on the lawn. Wild cats and dogs should be caught, and the lawn should not be strictly disinfected. In addition, residents should be disinfected frequently and be diligent in bask in the quilt!

Speaking of fleas, as the city becomes cleaner and cleaner, it seems that we haven't seen them for many years. How can it flood in "high-end" communities? In the face of these "difficult opponents", what can be done to completely eliminate them?

Let's listen to Lao Cheng's analysis:

Fleas, the reason why fleas are rampant, belong to the ectoparasites of animals or humans, and spread all over the world like cockroaches and bedbugs. It is a completely abnormal insect, generally living in a dark and humid place with humidity above 60% and temperature above 25℃. Rodents, such as dogs, cats and rats, are the main hosts and feed on blood (both males and females).

Because of its excellent jumping performance (maximum 19.7cm and maximum 33cm), fleas have one more survival ability than other parasites-they can change hosts at any time.

This determines that it can spread widely according to the host's activity range, and with its strong reproductive ability, it may develop into a large-scale population in just one or two months.

From the news reports about the "flea disaster" in Rongzunbao Community, Chaoyang District, Beijing, it can be preliminarily concluded that it was caused by wild cats or mice in the community.

The main reason is that the weather is getting cold, and wild cats are gradually moving from outdoor to underground garages. First, the temperature in the underground garage is higher than that outside the ground, and good people will feed cat food.

For these furry little guys who don't clean for a long time, it is the favorite host of fleas, and there is another host-mice.

As the weather turned cold, these animals gradually gathered in the garage. Appropriate temperature and sufficient "food" accelerate the reproduction of fleas, expand their population and constantly look for new hosts.

At this time, the flea's powerful talent is presented. It can pounce on people in a short time and suck blood through bare skin as its own food.

On April 20 12, the "flea disasters" in Lanjia Town of Changchun City, Dadong District of Shenyang City on April 20 12, Shuisong Community of Taijiang in Fuzhou City and Lixia District of Jinan City on June 20 14 were all caused by stray cats, dogs and mice.

How to kill fleas is very tenacious, not only running fast, jumping high, but the most terrible thing is that each adult flea lays 40~50 eggs a day, and these eggs can become adults in at least two weeks!

Imagine what a huge population two fleas will grow into in a month, provided there is enough food (many hosts)!

Therefore, if fleas are found, they must be eliminated in time, otherwise, according to its strong vitality and reproductive ability, it will have "disastrous" consequences.

Let's talk about how to eliminate public areas:

And for those who were bitten by fleas and accidentally brought home, what should I do?

How to prevent fleas from the last article, we can know the characteristics of fleas: like dark and humid environment, super mobility, super fertility!

If you want to prevent fleas, you must prevent them from their living habits and sources. If we don't give them breeding soil and lose their living environment, fleas will naturally become extinct!

In short, fleas can't survive as long as the environment is kept clean and the gathering of stray cats and dogs is reduced. After all, they can only live in dark and humid places and live on fresh blood. As long as the source is eliminated and the conditions for survival are lost, fleas cannot survive.

The first time I was bitten by a flea was when I was on holiday in senior three, working on the construction site. I just sat on the worker's bed and had a rest. When I went back, I was itchy and tossed for a long time.

From then on, I knew that there was no other way to get away from these little things except personal hygiene.

So is the "flea disaster" in public areas.

What do you think of this? Welcome to leave a message in the comment area ~ ~ ~

That is, cats and dogs are prohibited from outdoor activities, and the staff of the epidemic prevention station are required to kill the lawn in the community.

Animals are deworming in vitro, and people shake clean and enter the house.

Clean the sanitary corner at home and spray insecticide. Put a trap lamp on the ground at night, and it usually takes two or three weeks.
