At dusk, dark mosquitoes begin to fly indoors, so this is the best time to kill mosquitoes. The corner, ceiling, bed bottom and the back of the seat are the favorite places for mosquitoes to hide. Therefore, when spraying aerosol, special attention should be paid. People's misunderstanding in the process of using aerosol is that the amount used is too large, which is not effective. The key to the effect depends on the location of spraying. You should spray the medicine to the hiding place of mosquitoes in a proper amount, not all over the house. Mosquito-repellent incense should be placed in the upper air outlet when used, and it is best to start using it two or three hours before going to bed. It should be noted that the quality of coil incense mainly depends on whether the drugs applied are sufficient and easy to break, not that the bigger the smoke, the better, and the micro-smoke is the best.
Mosquito control method
Dredge the river, remove all kinds of stagnant water in time, and put in mosquito killing drugs for those stagnant water that cannot be removed, so as to fundamentally eliminate mosquito breeding places.
removing stagnant water is the key to killing mosquitoes: always check whether there is stagnant water in the sewers, open ditches and ceilings at home and outside, so as to prevent mosquito larvae from accumulating in landscape bonsai, refrigerator containers and fish and flower containers. Especially in the rainy season, a small amount of water should be removed from the green belt.
Use electric mosquito swatter, mosquito killer, electric mosquito-repellent incense, smoking and spraying mosquito repellent to indoor mosquitoes. When the density is high, spray with pest control spirit, and install screen doors, screens or light mosquito-repellent incense to protect yourself. When the mosquito density is high, it can be quickly killed, with 1: 1 fly-killing insecticide No.1 outdoors and pyrethroid insecticide sprayed indoors. At the same time, deal with the surrounding mosquito breeding grounds.
rational use of mosquito-killing products
When spraying with Mirex, doors and windows should be closed before use, and ventilation should be carried out 3 minutes after spraying.

A collection of mosquito prevention methods
It is well known that mosquitoes are annoying, which not only affects people's work, study and sleep, but also spreads diseases, such as malaria, Japanese encephalitis, filariasis and dengue fever. Recently, just after SARS retreated, a small-scale epidemic of "Japanese encephalitis" broke out in Guangdong. How to prevent and repel mosquitoes safely and effectively and spend the midsummer safely is a practical problem that everyone cares about.
Ways to prevent mosquitoes by indigenous methods
People take advantage of mosquitoes' habit of tending to light, liking high temperature, dark humidity and going out at night. In summer evening, they turn off indoor lights, open doors and windows, let mosquitoes fly outside, and then close screen doors to avoid mosquitoes flying in. Try to reduce the indoor air humidity, especially in the rainy season, and try to control the indoor relative humidity at about 5%. Put a few uncovered boxes of cool oil and essential oil in the bedroom, or put one or two pots of blooming cordate telosma, jasmine, Milan, mint or rose, etc. Mosquitoes can't stand their smells and avoid them. Install an orange light bulb indoors, or cover it with transparent orange cellophane. After turning on the light, mosquitoes will escape if they are afraid of orange light. Fill an empty wine bottle with sugar water or beer and put it in the shade. When mosquitoes smell sweet wine, they will drill into the bottle and be stuck to death by sugar water or beer. Spread a layer of repellent syrup evenly on the surface of containers such as glassware or ceramic crock, and put it face down in the dark. Mosquitoes will also be poisoned and die after smoking. Burning dried tea leaves and orange peels can repel mosquitoes. Eating garlic raw and taking vitamin B orally will be excreted from sweat after physiological metabolism, which will also produce an odor that mosquitoes dare not approach. In fact, it is also the simplest, most economical and most effective anti-mosquito measure to kill artificially on screen doors and screens before dark and after getting up in the morning.
Chemical mosquito repellent weapon
Mosquito-repellent incense is the oldest natural medicine to repel mosquitoes. As early as the Southern Song Dynasty, mosquito repellent incense sticks made of traditional Chinese medicine appeared. The effective component of modern mosquito-repellent incense is pyrethrin, which has the function of repelling and killing mosquitoes. After mosquito-repellent incense is ignited, pyrethroids in mosquito-repellent incense volatilize with smoke and spread in indoor air, which paralyzes mosquitoes' nerves, so mosquitoes either fall to the ground and die, or scatter, thus playing a role in repelling mosquitoes. Pyrethroids can be eliminated from the body through metabolism, which is not harmful to people. However, some inferior mosquito-repellent incense contains not only pyrethrins, but also bhc powder and realgar powder, which are toxic and even carcinogenic to human body. Therefore, mosquito-repellent incense is best used outdoors, such as around the home, at the door or in a place with good ventilation. Lighting mosquito-repellent incense before dark in the evening has the best mosquito repellent effect.
the mosquito repellent effect of the electric mosquito repellent incense tablet is also good, which generally lasts for 6-8 hours. The mosquito repellent principle of electric mosquito-repellent incense is that pyrethrum is inhaled into mosquito-repellent incense tablets and evaporated after heating, and the effect is better if a few drops of essential balm are dropped. Liquid electric mosquito-repellent incense is the most convenient to use by using the principle of wool straw to continuously heat and release pesticide substances. A bottle of mosquito-repellent incense can be used continuously for 3 days if it is used for eight hours every day, thus eliminating the trouble of replacing the electric mosquito-repellent incense tablets every day. However, both electric mosquito coils and liquid electric mosquito coils contain organic compounds harmful to human body. If used in a closed room, it may cause adverse reactions. Therefore, air circulation should be maintained when using electric mosquito coils. The best time to use electric mosquito-repellent incense is half an hour before going to bed.
Mosquito repellent, also known as mosquito repellent, is mainly used for people going out or working in the field. 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 anti-mosquito liquid. The principle is that drugs directly act on the tactile organs and chemoreceptors of mosquitoes, thus driving away mosquitoes. Children should pay special attention to the use of mosquito repellent, and it is best to use mosquito repellent with deet concentration less than 1%. Infants are prone to accidental licking poisoning, and it is best not to use it. When spraying anti-mosquito liquid, avoid spraying it directly on the wound or skin with red rash. You can spray it on your hands first, and then apply it to the exposed parts of your body one by one, which is a bit troublesome to use.
Mosquito-killing aerosol is a kind of insecticide, and its main chemical component is a substance called propargyl. Mosquitoes mostly like to hide in dark and humid places, and spray at stairwells, under sinks, sewers, bathrooms, cabinets, and under tables during the day. Use old boxes or buckets, put some rags in them, and arrange them into a dark and humid "artificial trap". Mosquitoes can fly in and rest during the day, and spray pesticides into them a few times, which is the unique skill of mosquito control experts. Mastering the time, place and dosage of mosquito control is the key. You don't need too much pesticide to achieve the effect. Too much pesticide will not only waste, but also increase pollution.
Mosquito-killing window screen coating is applied to the window screen to form a protective film by using the phototropism of mosquitoes and the principle of slow release of drugs. Mosquitoes and flies will die within two hours to several days after contacting for 3 seconds. Effective mosquito-killing ingredients are generally cypermethrin, cypermethrin and so on. When using, do not use alkaline solvent to clean the window screen. Its advantages are sun and water resistance, and its effective time is as long as several months to half a year.
experts remind people that because mosquitoes can also produce drug resistance, they should use different mosquito repellent methods and products in turn to achieve better mosquito repellent effect.
Physical mosquito repellent is the safest
The advantages of using mosquito nets are obvious, which can not only repel mosquitoes but also prevent wind, absorb falling dust and filter the air, especially suitable for children. However, mosquito nets are more troublesome to use, and the air inside them is not very fresh.
experts recommend the use of mosquito-catching lamps, which have no pollution. Mosquito-catching lamp uses the phototaxis and sensitivity of mosquitoes to special wavelengths. Ultraviolet light is attractive to mosquitoes. It traps mosquitoes to contact the net surface with a lamp tube, and uses high-voltage electric shock to make the mosquitoes scorch instantly. Choose a mosquito trap lamp with a luminosity of more than 8 watts or double tubes. It is best to place the mosquito lamp above the knee and not more than 18 cm from the ground. It is best to change the place often, and hidden corners and under the table are the best places. When using the mosquito trap lamp, all other indoor light sources should be turned off, because mosquitoes are disturbed, they can't feel the light source of the mosquito trap lamp, and the mosquito trap effect will be greatly reduced. Add some water and vinegar to the insect collecting box of mosquito catching lamp, and the mosquito catching effect is better, because mosquitoes have the habit of liking acidity. The principle and function of electric mosquito swatter are similar to those of mosquito catching lamp.
Mosquitoes are hard to prevent in the daytime, so it is better to wear long sleeves and trousers when going out. Try not to go to damp places with dense moss and grass as much as possible. You can also rub a little mosquito repellent to prevent it, or rub wormwood and eucalyptus leaves on your body, which is also effective. In short, according to personal conditions and circumstances, you can spend the summer happily by adopting comprehensive mosquito control and mosquito repellent methods.
