The biggest problem in summer is not only the heat, but also the biting of teeth. What's a good way to repel mosquitoes?
Local mosquito control
People make use of the habit of mosquitoes tending to light, preferring high temperature, dark humidity and nocturnal night. In the summer evening, they close the indoor light, open the doors and windows, let the mosquitoes fly to the outdoor, and then close the screen door tightly to avoid mosquitoes flying in. They try to reduce the indoor air humidity, especially the rainy season, and try to control the indoor relative humidity at about 50% as much as possible. In the bedroom, put several boxes of uncovering cool oil and essential balm, or one or two basins of blooming night primrose, jasmine, Milan, mint or rose. Mosquitoes can't stand their smell and avoid it. Install orange light bulb indoors, or use transparent orange cellophane to cover the bulb. When the lamp is turned on, mosquitoes are afraid that orange light will escape. Put sugar water or beer into an empty wine bottle in the dark place, and mosquitoes will drill into the bottle when they smell sweet wine, and they will be stuck by sugar water or beer to death; evenly spread a layer of qusuiling syrup on the surface of glassware or ceramic pots, and put it in the dark place with the mouth facing down, and mosquitoes will also be poisoned and die after smoking. Burning the dried tea leaves and orange peel can repel mosquitoes. Eating garlic raw and taking vitamin B orally will also produce an odor that mosquitoes dare not approach when it is discharged from the body through sweat after physiological metabolism. In fact, every day before dark and after getting up in the morning, it is the simplest, most economical and most effective mosquito control measures to hunt on screen doors and windows.
Chemical mosquito repellent weapon
Mosquito repellent incense is the oldest natural medicine to repel mosquitoes. As early as the Southern Song Dynasty, there were mosquito repellent sticks made of traditional Chinese medicine. The effective component of modern mosquito repellent incense is pyrethroid, which has the function of repelling and killing mosquitoes. After the mosquito repellent incense is ignited, the pyrethroids in the mosquito repellent incense volatilize with the smoke and spread in the indoor air, paralyzing the mosquito's nerves, so the mosquito either falls to the ground and dies, or runs away in all directions, thus playing the role of killing the mosquito. Pyrethroids can be metabolized out of the body without much harm to people. However, some inferior mosquito repellent incense, in addition to containing pyrethroids, also contains BHC powder, realgar powder, etc., which are toxic to human body and even carcinogenic. Therefore, it is better to use mosquito repellent incense outdoors, such as around the house, at the door or in the air circulation place. In the evening, the best effect is to light mosquito repellent incense before dark.
The mosquito repellent effect of electric mosquito repellent incense is also good, which can be maintained for 6-8 hours generally. The mosquito repellent principle of electric mosquito repellent incense is to inhale pyrethrum and other insecticides into mosquito repellent incense sheets, heat them and evaporate them. If you drop several drops of Aeolian essence, the effect is better. Liquid electric mosquito repellent incense is a kind of insecticide released by continuous heating based on the principle of capillary, which is most convenient to use. According to the calculation of using eight hours a day, a bottle of mosquito repellent liquid can be used for 30 days continuously, avoiding the trouble of replacing the electric mosquito repellent every day. But whether it is electric mosquito repellent or liquid electric mosquito repellent, there are harmful organic compounds. If used in a closed room, adverse reactions may occur. Therefore, air circulation should be maintained when using electric mosquito repellent incense. The best use time of electric mosquito repellent incense is half an hour before going to bed.
Mosquito repellent, also known as repellent, is mainly used for people to go out or field workers. The main component of mosquito repellent is DEET. It is said that 99.9% of mosquito bites can be prevented within 6-8 hours by applying qualified mosquito repellent. The principle is that drugs directly act on the mosquito's tactile organs and chemical receptors, thus driving away mosquitoes. Children should pay special attention to the use of mosquito repellent, the best use of DEET concentration less than 10% of the mosquito repellent. It's easy for babies to be poisoned by licking. It's better not to use it. When spraying mosquito repellent, avoid spraying it directly on the wound or the skin with rash. Can spray on the hand first, then daub on the naked part of the body one by one, it's a bit troublesome to use.
Mosquito aerosol is a kind of insecticide, its main chemical component is a kind of substance called propargylide. Mosquitos mostly like to hide in dark and humid places. During the day, they spray on staircases, sinks, gullies, bathrooms, cabinets, tables, etc. Use the old box or bucket, put some rags in it, and arrange it into a dark and humid 'artificial trap'. In the daytime, mosquitoes fly in to rest and spray insecticides into it for a few times, which can easily kill mosquitoes. This is the unique skill of anti mosquito experts. It is the key to master the time, place and dosage of mosquito control. Insecticides do not need too much to achieve the effect, which not only wastes, but also increases pollution.
Mosquito screen coating is to apply mosquito screen coating on the screen window based on the phototropism of the mosquito and the slow-release principle of the drug, forming a protective film. After 30 seconds of contact, the mosquito and fly will die within two hours to several days. The effective mosquito killing ingredients are generally chlorchrysanthelmide and chlorhexidine. When using, do not use alkaline solvent to clean the window screen. The utility model has the advantages of sun and water resistance, and the effective time is months to half a year.
Experts remind people that because mosquitoes can also produce resistance, they should take turns to use different mosquito repellent methods and products to get better mosquito repellent effect.
Physical mosquito repellent is the safest
The advantages of using mosquito net are obvious. It can not only avoid mosquito and wind, but also absorb falling dust and filter air, especially suitable for children. However, the use of mosquito nets is more troublesome, and the air in the nets is not very fresh.
Experts recommend the use of mosquito traps, no pollution. Mosquito trap lamp is to use the phototaxis of mosquitoes and the sensitivity to special wavelengths. The ultraviolet light is attractive to mosquitoes. The lamp is used to trap mosquitoes on the contact net surface, and the high-voltage electric wire is used to instantly scorch mosquitoes. Choose a mosquito trap lamp with a luminosity of more than 8 watts or double lamp tubes. Mosquito traps should be placed at a place higher than the knee and no more than 180 cm above the ground. It's better to change the place often. The best place is the corner and under the table. When using mosquito lamp, all other indoor light sources should be turned off. Because the mosquito is disturbed, the light source of mosquito lamp cannot be felt, and the mosquito catching effect will be greatly reduced. Add some water and vinegar to the insect collecting box of the mosquito catching lamp, the mosquito catching effect is better, because the mosquito has the habit of liking acidity. The principle and function of electric mosquito swatter is similar to that of mosquito trap lamp.
Mosquitoes are hard to control in the daytime. It's better to wear long sleeves and trousers when you go out. Try not to go to wet places with dense moss and grass as much as possible. You can also rub a little mosquito repellent to prevent it, or rub the wormwood and eucalyptus leaves on your body, which has some effect. In short, according to personal conditions and circumstances, you can enjoy the summer by adopting comprehensive mosquito control and repellent methods.
