According to reports, in recent days, in a residential area in Beijing's Chaoyang District, many residents have a lot of small red dots on their bodies, and after going to the hospital for examination, they were told that they were flea bites.
<h1 class="pgc-h-arrow-right" data-track="2" > so where do the fleas in this cell come from? </h1>
After investigation, it was found that the original underground garage of Block C of the community has been flooded with fleas since autumn, and now it has spread to the elevator halls and corridors, and even some low-rise residents have also appeared in the homes of many fleas.
Naturally, residents usually come in and out, and it is inevitable that they will be bitten by fleas. However, there is also a new problem here, we all know that with the improvement of living standards, people's awareness of hygiene, in fact, fleas have been very rare, so why in this community, suddenly there are so many fleas?
In this regard, local residents speculate that it may be that since the beginning of autumn, the underground garage of the community has become a "wild cat home", because many of the wild cats carry fleas, and the fleas are very strong in breeding, a female fleas can lay 200-400 eggs in a lifetime, which also leads to an increase in their number of multiples, and soon flooded.
I have to say that this looks really scary, after all, fleas are small insects that are not easy to be detected, and they not only suck blood, but also spread diseases, and even some people who have pets in their homes are infected by fleas on their pets at home.
<h1 class="pgc-h-arrow-right" data-track="22" > so why do fleas suck blood? How exactly did they come about? </h1>
Fleas are a very tenacious species, in the natural environment, a fleas lifespan, up to more than 2 years, you know, under normal circumstances, few small insects can live so long, which also makes fleas become one of the pests that are difficult to be eliminated, especially for humans and mammals, it can be described as extremely harmful.
However, studies have found that in the early days of fleas evolution, they were actually not blood-sucking, and at that time, fleas were not only very large, but also could not jump, which was very unexpected.
In January this year, researchers from the Chinese Academy of Sciences, together with a team of British scientists, conducted a thorough "tracing" of fleas, and found that the early fleas were about 4 times the size of modern fleas, and they did not parasitize other animals, but lived in lush vegetation such as forests, by sucking the sap of plants, or preying on some small insects.
So, how did the flea later live a "sojourn" life? At present, the oldest "parasitic fleas" found by scientists are from 150 million years ago, this fleas parasitized on a dinosaur, and were found from dinosaur fossils in the process of archaeological excavations by scientists.
Until then, scientists had thought that fleas didn't start to become "parasitics" until after the emergence of mammals and birds, and apparently, in fact, they began to parasitize much earlier than we thought.
In the course of their research, scientists found that fleas began to parasitize dinosaurs as early as the Jurassic period, and until the Cretaceous mass extinction, fleas were based on dinosaurs as the main host.
It was not until after the extinction of the dinosaurs that fleas began to find new hosts for themselves, which were transferred to early birds and mammals, and continue to this day.
<h1 class="pgc-h-arrow-right" data-track="23" > so what if you get bitten by fleas? </h1>
Fleas can be transmitted between humans and other animals (mainly mammals) at the same time, which also means that if people usually contact stray animals more, or have pet cats and dogs at home, it is entirely possible to be bitten by fleas on them.
Therefore, it is also recommended here that if there are pets in the home, then it is best not to use carpets, at the same time, to often bathe animals, build hair, at the same time, but also to keep the environment in the house clean, otherwise once there are fleas in the house, it is difficult to cure in the short term, do not take it lightly.
If you are accidentally bitten by fleas, you can apply soapy water, wind oil essence, flower dew water, etc. that can be used to relieve itching and anti-inflammatory at the site of the bite.
At the same time, intimate clothing must also be disinfected with boiling water, so that the eggs on it can be removed, in addition, if you find fleas at home, you can also spray some potions to drive away fleas, etc., so as to keep them away from themselves.
Of course, in fact, now fleas in the city, has been very rare, after all, people's health habits have undergone great changes, but not afraid of ten thousand is afraid of just in case, take this time in a community in Beijing, suddenly flea flooding, in the short term, governance will be very difficult, which also to local residents, caused a lot of trouble and harm, so, in ordinary life, we still need to pay attention to prevention.
