Every summer, many people's mood becomes very irritable. One reason is that the temperature is too high in summer, and the heat will make people feel bad, and another reason is that when summer comes, annoying flies will buzz around us.
flies
Not only that, but the flies are always on top of our food and can't be chased away, which is annoying but helpless. But in fact, if you observe them carefully, you will find that they are actually very interesting, with many cute little actions.
Flies rub hands and feet
For example, they like to rub hands and feet, especially after smelling delicious food, flies will rub their hands and feet more severely. Seeing this, we can't help but wonder, why are flies rubbing hands and feet when it's not cold in winter? Are the spring and summer perceptions of flies the opposite of those of humans? Now I will clear this doubt for you.
Habits and body structure of flies
We are all familiar with flies, and flies like to appear in some places where the environment is not very clean. Like garbage heaps, rotting food, near toilets. Flies are omnivorous insects. Their feeding habits depend on their species. For example, fruit fly prefers to eat some rotten fruits, while housefly , which is common in our lives, eats more widely.

like human food,Or the body fluids and excrement of livestock and poultry it likes to eat. They are also found in kitchen waste and near sewers. Although the sparrow is small, it has all the internal organs. The largest fly in the world can reach 8 cm, but our common house fly is only the size of a soybean grain, less than an inch, and its volume and weight are not large.
Structure of the fly
The entire body of the fly consists of three body segments: head, thorax and abdomen. The head is the sensory and feeding center, with a pair of antennae and a mouthpart, and eyes. The thorax is the center of movement, with three pairs of feet (legs), and two pairs of wings. The abdomen is the reproductive and metabolic center, containing most of the internal organs and their reproductive organs.
Reasons why flies rub their hands
Flies rub their hands to clean their legs and to ensure that their sense of touch and taste are not affected. From the above understanding of the body structure of flies, we can know that the body of flies does not have a nose, so in order to smell and distinguish food types, they rely on the taste and touch sensory organs of their legs.
The flies rub their hands
The flies' food like feces, kitchen waste, etc. will make their legs stick to mucus, so it is not conducive to the flies' taste and touch. In order to correctly distinguish smells and to be more comfortable, flies will constantly rub their hands and feet to ensure the sensitivity of their legs' taste and touch organs. At the same time, in order to cling to smooth walls, flies secrete a liquid with a certain adhesive force.It will also stain their legs.
Life history of the fly
The sole of each foot of a fly has a row of parts covered by fly hairs, which we call a pad. When it hits a wall as smooth as glass, this adhesive liquid keeps the fly firmly attached to the glass and will not fall off.
However, the secreted liquid and food mucus will remain on the feet of the flies. In order to keep the sense of touch and taste unaffected, the flies will frequently rub their hands and feet to clean the legs. The same is true for humans. When we have a cold, our nose is blocked, and our nasal passages are covered with mucus. We are uncomfortable and can’t smell the smell. Therefore, in order to feel comfortable and smell the smell, we often rub our nose.

The second is to reduce weight and facilitate take-off and landing. As we all know, flying animals are not very big. The same goes for flies, which are not very bulky or heavy. So in order to fly, flies must regularly wipe off the contaminated food from their feet to lose weight. Flies are so annoying in the human world. If they can't fly away quickly to avoid human attacks, only death awaits them. So flies rub their hands to survive.
Flying flies
The third is to mate for face and reproduction. In the fly world, there is a market for flies that love to rub their feet. Although flies often love to go to dirty places, they love to clean themselves. Studies have shown that when there are many flies, the flies will rub their hands more frequently. That is to say, when other flies are present, the flies will pay more attention to their own face and are more willing to clean their own bodies.Let other flies think they are clean and beautiful.

Scientists also found that flies frequently rub their hands not only to save face, but also to secrete pheromones to promote mating. During the mating and breeding season of flies, female flies will rub their hands to release their own pheromones. When encountering male flies, they will speed up rubbing their hands to secrete more pheromones to attract males to mate with them.
How to effectively kill flies
Every summer is the season of flies and mosquitoes. Flies harass people and animals, pollute the environment, and spread diseases. Together with mosquitoes, mice, and cockroaches, they are called " and four pests " by humans. By understanding the habits of flies above, we know that they like to go to dirty places and people who like to sweat.
has nothing to do with what we used to think about blood type or blood smell. So if you want to reduce the number of flies in your home, one of the easiest things to do is to clean frequently, take out more garbage and clean the sewers, so as to reduce the food source of flies. People who like to sweat, bathe frequently and change clothes frequently.

Second, through drug control. When summer comes, we can prepare more insecticides at home. Among them, the insecticides containing phosphorus and carbamate have a higher insecticidal rate, so we can prepare more at home.
Third,We can take advantage of the fact that flies like yellow to eliminate flies. Hang more yellow boards covered with insecticides or put more yellow sticky paper at home. At the same time, the use of yellow items such as sheets can be reduced at home in summer.
UV lamp for fly
Fourth, you can learn the practice of many restaurants and hang a 365nm UV lamp . Biologists have found that flies are extremely sensitive to the spectrum around 365nm by testing the photoelectric response of flies. At the same time, the existence of ultraviolet rays can also effectively control other insects in summer, and the ultraviolet rays of 365nm are harmless to the human body. Therefore, hanging 365nm UV lamps at home is also an effective way to control flies.
Conclusion
The small movement of "rubbing hands and feet" that flies often appear is a physiological behavior of them. Like we humans rub our noses. Flies "rub hands and feet" both for mating and reproduction, but also to identify food. Flies are well-known as one of the four pests, which can spread diseases, pollute the environment, and be detrimental to people's health.
flies
Some species of flies can even pierce the skin of humans and livestock, suck blood, and parasitize our bodies. Therefore, in order to effectively control the reproduction of flies, we should reduce their food sources and keep them clean and tidy, both in society and in the family.
