How to kill mosquitoes and flies: four ways to kill flies with family medicine

● Drug maggot killing: In public places, septic tanks, garbage dumps and other places where there are many fly larvae, using 0.2% malathion emulsion and 0.2% fenitrothion emulsion, spraying at a speed of 500 ml per square meter, can effectively kill fly maggots.

● Drug fly killing: Space spraying is a quick way to kill flies. Manual sprayers, ultra-low volume sprayers or commercially available spray cans are usually used. The commonly used chemicals are 0.3% to 0.5% dichlorvos.

● Retention spraying: This is an effective method to kill flies. Mainly used in toilets, barns and other places where there are many flies, spraying chemicals on doors, windows, walls, ceilings and other places where flies stop. The commonly used chemical is 5% beta-cypermethrin.

● Poison rope to kill flies: Using the habit that houseflies like to stay on ropes and other hanging objects, soak cotton (hemp) ropes or cloth strips with a diameter of 2-4 cm in chemicals to dry, cut them into lengths of about 1 to 2 meters, and hang them under the indoor ceiling at a distance of 2-2.5 meters from the ground. Generally, 2 ~ 3 pieces can be placed per 10 meter. The insecticide available for soaking is 10% methylpyrazine.

Attention should be paid to environmental management in the prevention and control of houseflies.

(1) Clean up the breeding ground of flies, especially the sanitary dead corner, and lay eggs in contact with the breeding ground. So flies can't come into contact with evil creatures to lay eggs.

Domestic garbage should be bagged and daily cleaned. The garbage left around the trash can is most likely to breed maggots, so it should be washed with clear water.

(two) timely and proper disposal of human and animal feces.

Some families keep pets, and their feces and urine should be cleaned up in time and properly handled. Some toilets in rural areas are open and need to be rebuilt. Cover the excrement outlet and squatting position to reduce the breeding of flies. The hardening of the soil around the cesspit will destroy the pupa.

(3) Raw and cooked vegetable rice is stored seamlessly and without holes.

If there is a gap in the vegetable rice container and the food remains outside, it will be polluted by flies and lead to the breeding of maggots.

(4) Install screen doors and screens to prevent flies from flying in.

Fourth, physical prevention and control.

(a) food and tableware covered with fly nets.

(2) Flies beat dead flies.

The fly swatter is a simple fly killing device, which can effectively kill flies by swatting at the sight of flies.

(3) Catch flies with flying paper, flying belt and flying rope.

In kitchens and restaurants, flies like to stay on drooping ropes, and they can be hung by sticky fly belts and sticky fly ropes.

Fly-sticky paper can be placed on tables, stoves, near windows and other places to catch flies.

(4) The fly trap kills flies.

Using the characteristics that flies like to emit fragrance and smell, fly traps can be used to kill flies. The fly trap is suitable for catching flies outdoors. The anti-fly facilities in rural families are often incomplete, and there are many flies in front of and behind the house. The fly trap can not only kill many flies, but also attract indoor flies and reduce indoor flies. When using the fly trap, we should pay attention to the choice of bait. The distance between the bait and the lower mouth of the fly trap is generally 2cm, and the height of the bait is about1.5 mm. In order to prevent the bait from maggots, the bait should be changed regularly.

(5) Install the fly-killing lamp.

Conditional families can install fly-killing lamps under the guidance of professionals, and the fly-killing lamps should be installed in dark places.

The best way to kill flies is to deal with substances suitable for fly reproduction. If the garbage is bagged (the bag should be intact and the mouth of the bag should be tightly tied), do not litter, properly handle pet feces, etc.

Mosquitoes: Generally, mosquitoes begin to appear in April every year and reach the peak in the middle and late August. When the climate gets cold in autumn and the temperature drops below 10 degrees Celsius, mosquitoes will stop breeding, go into hibernation without eating, and come out to harm people until they wake up the next spring. The most suitable temperature for mosquitoes is about 30℃, which is too high for them.

The family environment should do the following:

1. Check the pots, pans, floor drains, sewers, flowerpots and other places with stagnant water at home, cover them with covers and change the water frequently. Floor drains, sewers and other places to prevent water accumulation, often spraying some pesticides, not giving mosquitoes living space.

2. Water should be changed regularly for aquatic plants at home.

Pay attention to close the screen window and screen door, and don't leave the door wide open for mosquitoes to come in directly.

4. Don't throw cans, mineral water bottles, egg shells and other rubbish that is easy to accumulate water. It's best to use the kind with a lid on the trash can.

5. If you are on a business trip or don't live for a long time, cover the toilet and clean the water in the sink to prevent mosquitoes from laying eggs.

Five measures to prevent mosquitoes in summer

Mosquito bites are affected by three factors:

First, the carbon dioxide exhaled by the respiratory tract is the directional odor source of mosquitoes, which can help mosquitoes find people and then bite.

The second is the heat. Fat people are more likely to be bitten by mosquitoes. Dark clothes absorb heat to attract mosquitoes.

The third is excrement. Mosquitoes love to bite people with big pores and sweat. Generally, men attract more mosquitoes than women, young people attract more mosquitoes than the elderly, and healthy people attract more mosquitoes than patients because there are more secretions on the skin surface. Moreover, children have a strong metabolism and are also favored by mosquitoes.

In addition, when women come to menstruation, their secretions will change, thus attracting mosquitoes.

Sweating will attract mosquitoes, so experts suggest taking a bath after exercise. If you sweat less, mosquitoes will bite less.

So, how to prevent mosquito bites? According to experts, there are five measures to prevent mosquitoes in summer:

First, it is best to use less soap when bathing in summer. Generally speaking, mosquitoes like nectar, so the probability of being bitten by mosquitoes will increase after using perfume, cosmetics, cream and other items with floral fragrance. However, not all smells will provoke mosquitoes. For example, the cologne commonly used by men can repel mosquitoes because of its sandalwood smell.

Second, eat more vegetables. Some vegetables contain odors that mosquitoes don't like, such as vegetables containing carotene, garlic and other spicy vegetables. After people eat it, mosquitoes will stay away from you.

Third, wear light clothes. Aedes mosquitoes (also known as spotted mosquitoes) like to park on black clothes.

Fourth, try to wear socks. Many girls like to wear shoes barefoot, but they don't know that after wearing socks, mosquitoes feel that people's skin humidity is reduced, and the volatiles on the skin surface are reduced, which will reduce bites.

Fifth, you can't catch it after being bitten. After scratching, the tissue fluid and lymph in the skin ooze out and swell into blisters, which will become more and more itchy and will not fade easily. If you insist on not grasping, the itching will obviously subside after 10 to 15 minutes.

Folk mosquito repellent has a strange trick.

Bottle-induced mosquito killing method: use some empty wine bottles, each bottle contains about 10 ml of sugar water solution, and gently shake it a few times to make the sugar water stick around the inner wall of the bottle and put it in the place where mosquitoes are active. When mosquitoes smell sugar, they will automatically fall into the "trap in the bottle" and get stuck.

Take medicine to repel mosquitoes: take some vitamin B in moderation every day. After taking it, vitamin B is excreted from sweat or urine through human metabolism, which will produce some special smells. Mosquitoes hate the smell, so they dare not go near the human body.

Desk fan mosquito repellent method: Mosquitoes are prone to glow at night, so after turning off all the lights at home, use a desk fan with an indicator light and swing it at a large angle, and the blades will kill many mosquitoes.

Smoke to repel mosquitoes: in the room, put some sawdust, preferably scented sawdust, on the sawdust, put some red-hot charcoal, and then put some dried citrus, orange or grapefruit peel on it. After burning, it will give off a very strong smell, and mosquitoes will "stay away from it" when they smell it.

Orange cellophane mosquito repellent method: put orange cellophane with strong light transmittance on a 60-watt light bulb, and mosquitoes will flee everywhere.

Dry orange peel mosquito repellent method: light a few pieces of dry orange peel or orange peel indoors, and mosquitoes will flee in a hurry.

Mosquito repellent method: use appropriate amount of mint leaves, perilla leaves or tomato leaves, knead into juice and apply it to the naked skin of human body. Mosquitoes will smell the special smell of these plant juices for fear of avoiding them.
