What are the effective ways to get rid of mosquitoes.
-
The researchers studied the behaviour of Anopheles arabiae mosquitoes in three villages in western Ethiopia. They found that indoors, they preferred human blood, while outdoors, they preferred to suck the blood of cattle and sheep.
However, there is one exception, and that is chickens. Regardless of whether it is indoor or outdoor, chickens do not attract mosquito bites.
After discovering this phenomenon, the researchers collected cow hair, wool and chicken feathers in the village, identified and analyzed these smell** compounds, and then compared the odors of different species ** to see which smell mosquitoes hate the most.
Sure enough, mosquitoes hate the smell of chickens the most.
In this regard, the researchers said that chicken smell is a natural mosquito repellent.
In order to test this conjecture, volunteers were even hired to conduct human experiments to attract mosquitoes. Volunteers slept in thatched huts without any shelter in the village, and then set up mosquito repellent with different smells, including the smell of chicken. Researchers have found that the smell of chicken is the most effective at keeping mosquitoes away than other flavors.
Incredibly, mosquito repellent can be carried out even if there is a live chicken coop hanging outside the thatched hut.
It's unclear why mosquitoes hate the smell of chickens. Researchers speculate that mosquitoes may have evolved the ability to avoid birds by recognizing their air chains and smells, including the smell of chickens, perhaps because birds prey on them.
Whatever the reason, at least we know an alternative mosquito repellent that is to hang a chicken in front of your house or window. And this mosquito repellent method is very environmentally friendly, but remember to often take off the chicken's bumper edge, feed the chicken rice, and remember to clean it when pooping to avoid peculiar smells.

When summer arrives, mosquito bites are inevitable. When a mosquito bites, it secretes an organic acid, formic acid, in the mouthparts of the mosquito, and its chemical composition is HCOOH. This substance can cause muscle acid, which can be applied with a strong soap in the home to quickly relieve itching.
The reason is the sodium salt of the higher fatty acids of soap. Such as: C17H35COONA.
The sodium salt of this fatty acid is alkaline when hydrolyzed. Contains OH-
Formic acid aqueous solution contains H+:
Because the OH- in the soapy water is neutralized with the H+ of formic acid to form H2O, it can quickly eliminate the itch.
After being bitten by mosquitoes, do not scratch indiscriminately, otherwise it is easy to cause bacterial infection. Experts recommend that the following methods be used to relieve itching:
1.After being bitten by mosquitoes, ordinary people will have symptoms such as redness, swelling, itching, and pain, and alkaline substances can be used at this time.
For example, ammonia can be used to relieve itching, or soap can be dipped in water to apply to the red and swollen area.
It relieves itching within minutes.
2.If the bite is very itchy, you can flick it with your fingers first, and then apply flower water, wind oil essence, etc.
3.Apply or brew the itchy area with salt water, which will soften the bump and can also effectively relieve itching.
4.The sap from the aloe vera leaf can be used to relieve itching. When it is red, swollen and itchy after being bitten by a mosquito, you can cut a small piece of aloe vera.
leaves, after washing, break open, rub a few times on the red and swollen area, you can reduce swelling and relieve itching.
Why do mosquito bites swell?
In fact, it should be said that it was stung by mosquitoes. Mosquitoes can't open their mouths, so they won't bite on the **, they actually use six needle-like structures to pierce people's **, and these mouth needles (stylets) form the center of the mouthparts.
These needles suck in blood in the same way that they draw blood; The mosquito also releases saliva containing anticoagulants to prevent blood from clotting, so it can feast peacefully. When the mosquitoes are full of food and drink and float away, all they leave behind is an itchy lump.
How to stop itching after being bitten by a mosquito?
Female mosquitoes suck blood in order to get protein in the blood to nourish the ovaries, so the saliva of female mosquitoes will secrete an organic acid similar to an anticoagulant, so that the blood will not coagulate, but the organic acid left on the human ** is a foreign substance, and some people will produce allergies, such as itching and swelling.
At this time, it can be neutralized with alkaline substances, such as applying ammonia to relieve itching.
The application of panacea and salt allows local anesthesia and soothes nerves, relieving the feeling of itching.
Grinding aspirin pills and applying water to the wound also has anti-inflammatory and swelling effects, Wang Zhengxiong suggests.
If you are sensitive to mosquito bites, you may wish to take an antihistamine pill before going out.
Recently, Finland reported that antihistamines block the immune response and can reduce itching and swelling from mosquito bites.
But antihistamine *** is want to sleep, motorists avoid taking it.

If you bring chickens, it will be more troublesome, but if you don't bring chickens, I don't think you will ask.
If you take chickens to disinfect or kill mosquitoes and flies, you need to consider the impact on chickens and the impact they may be exposed to. I don't know how the chicken farm is closed.
First of all, it is fundamental to identify and treat possible breeding grounds for mosquitoes and flies in and around the venue.
Secondly, it is the use of mosquito control drugs in the field, and the comprehensive use of drugs can be carried out on the walls and floors of the field and in some of the spaces that can be used, so as to kill them at the time and stay in them later.
Secondly, such as top or other places that are inconvenient to use medicine, but cannot be reached by chickens, you can brush the medicine at a higher concentration, and use the residual medicine according to the characteristics of mosquitoes that like to stay in warmer and darker places.
After the operation of the upper two parts, the density of mosquitoes in the space will be greatly reduced. In addition, there is a retention drug, and then there will be a certain period of time according to the effect of the product, and there will be no longer worrying about mosquitoes. If you want to reduce it further, you can use ordinary mosquito coil tablets and use a small amount of fumigation to repel the remaining mosquitoes.
After that, pay attention to the sealing of the environment in the field. In the use of medicine, according to the size of their own field, the size of the chicken, the specific usage of the drug, the dosage, the amount of water, etc., the use of comprehensive consideration.
The significance of the existence of mosquitoes is to maintain the balance of the ecological environment. >>>More
When planting chicken fir fungus artificially, the climate is particularly important, it is most suitable for growing in an environment of about 25 degrees, and the humidity of the planting environment is also very important, if the environmental humidity is too high, the chicken fir fungus will be too watery, if the humidity is too low, the chicken fir fungus will be particularly dry, so the growers should pay attention to the humidity adjustment. Chicken fir fungus is a wild fungus, its growth and the survival of termites in the wild has a very important relationship, if there is no termite this fungus will not grow at all, so it is best to go to the mountains to choose a place with termites to take soil, there will be some termite holes in these soils, it will also be conducive to the growth of chicken fir fungus natural ingredients, if there is no such natural soil, it is difficult to artificially grow chicken fir fungus. >>>More
Take medicine to repel mosquitoes: Take some B vitamins in moderation every day. After taking it, vitamin B is metabolized by the human body and excreted from sweat or urine, which will produce some special smells, which mosquitoes hate very much, so they dare not approach the human body. >>>More
