Almost everyone has a bad experience of being bitten by a mosquito. Mosquito bites can cause skin irritation through an allergic reaction to mosquito saliva, causing red bumps and itching. But the more serious consequences of some mosquito bites may be the transmission of serious diseases and viruses, such as Zika virus.
What is Zika virus disease?In Uganda on the shore of Lake Victoria in East Africa, there is a forest called Zika, where monkeys are mostly infected with yellow fever. In April 1947, scientists funded by The National Institute for Medical Research (London, UK) and the Rockefick University Foundation in the United States isolated an undocumented species of monkeys living in this forest. Because the place where the virus was isolated was Zika, scientists named it "Zika virus."
Zika virus disease is an acute viral disease caused by Zika virus. It is mainly transmitted through mosquito bites. The common symptoms are acute fever with rash, joint pain, and conjunctivitis. Other symptoms include myalgia and headache.
How does Zika virus spread?Zika virus is mainly spread in tropical areas with a large number of mosquitoes. It is mainly spread through mosquito bites. Humans are the host of the disease. This means that mosquitoes will infect Zika virus from infected people in the first week of symptoms. The mosquitoes can then spread the disease to other people through their bites.
Preventive measures for Zika virusAt present, people have no effective measures to defeat the Zika virus. WHO recommends that the prevention and control of the virus requires reduction of sources (eliminating or changing breeding sites) to reduce mosquito breeding and to reduce the contact between mosquitoes and people. By taking the following measures, mosquito bites can be prevented, and viruses can be prevented and controlled.
1. Install screen doors and windows
Screen doors and screens can be installed in the room to prevent mosquitoes from entering the room. In the high-incidence period, the screens can be coated with insecticides sprayed on them for better effect. Use mosquito nets during rest to reduce human exposure to mosquitoes.
2. Don't expose the skin
Wear clothes that can completely cover your arms, legs, feet, neck, and head (long sleeves, pants, long skirts, and things that cover your head, such as hats, etc.).
3. Clear breeding grounds
Resident household vases and aquatic plants should be thoroughly changed at least once a week. The air-conditioning trays and the bottom plates (trays) of flower pots should be thoroughly cleaned of water, and covered with lids. Check the floor drains in toilets and kitchens every week or replace safe floor drains with anti-seepage functions. Keep the floor drains free of water and spray insecticides frequently. Do not give mosquitoes living space, and the trash can should be covered.
4. Use all kinds of sanitary insecticides correctly Use insecticidal aerosol to kill mosquitoes. When using insecticidal aerosol, try not to spray directly on clothing, sheets, furniture, and skin. Before spraying, store food and tableware. It is best to close doors and windows for half an hour after spraying. 1 hour, then open the windows for ventilation. Excessive spraying of insecticidal aerosol will be toxic to the human body, so you must pay attention to safety when using insecticidal aerosol at home, do not let infants and young children touch it, if you accidentally spray the liquid on the skin, wash it in time . You can also use mosquito coils. You can use mosquito coils. Follow the instructions to repel mosquitoes and kill mosquitoes. Place the mosquito coils in a ventilated place upwind.
Regarding mosquito coils, Arrow mosquito coils are a good choice. Arrow is a brand of Jiangsu AoGrand Daily Chemical Group Co., Ltd. It belongs to AoGrand Group, which has more than 20 years of professional scientific research and production experience. Its products are mainly concentrated in mosquito killing products. Covers mosquito coils, electric mosquito coils, electric mosquito coils, insecticide sprays, etc. The products are sold at home and abroad and are the first choice for mosquito repellent! Arrow mosquito repellent products are smokeless, tasteless, safe and reliable, allowing you to bid farewell to the bitterness of mosquitoes. As a daily chemical company with 20 years of experience, we can provide you with some knowledge about mosquito coils.
The main ingredients of mosquito coils: Mosquito coils are incense sticks containing pyrethrum, which use high-temperature combustion to slowly release insecticides into the air The smoke released has the effect of killing mosquitoes. The ingredients of mosquito coils are: organophosphates (trichlorfon/chlorpyrifos/pest enemy), carbamates (proxacarb/hypermethrin), pyrethroids (cyfluthrin/ cypermethrin/ propinyl methrin/ propylene) Pyrethrin/ES biological pyrethrin), of which organophosphorus is the most toxic, and pyrethroid is the weakest, which is slightly toxic.
The active ingredients of most mosquito coils are pyrethroid insecticides. More than 90% of the mosquito coils on the market contain pyrethroid insecticides. It is a low-toxic and highly effective insecticide allowed by the state, and it is used in mosquito coils. Traditional mosquito coil smoke contains fine particles, polycyclic aromatic hydrocarbons, carbonyl compounds and benzene. Although it may be a threat to the human body, due to its small content, reasonable use is basically harmless.
Types of mosquito coils 1. Mosquito coil Advantages:
(1) The insecticide formula of the mosquito coil can be adjusted at will, the mosquitoes are not easy to adapt, and the mosquito repelling effect is good; (2) The insecticide is evenly distributed on the mosquito coil, and gradually heated, the insecticide is evenly dispersed, and the mosquito repelling effect is stable (3) No power supply needed; (4) The price is cheaper.
Disadvantages: (1) Fixed use time cannot be guaranteed; (2) There are health-hazardous ingredients in the smoke of wooden mosquito coils, which can pollute the space environment and contaminate objects; (3) Open flames are ignited, potentially causing a fire hazard; (4) Insecticides inside the mosquito coils when ignited Too late to evaporate (especially the disc-type mosquito coils produced by traditional techniques), about 30-40% of the insecticides are decomposed by heat and lose their role in repelling mosquitoes; (5) It requires a lot of equipment investment, the construction of large workshops and the use of large quantities of insecticides. Labor; (6) Consume a lot of precious wood resources.
2. Electric heating sheet mosquito coil
Advantages: (1) No smoke, no peculiar smell, no ash, no pollution; (2) PTC heating source, safe and hygienic; (3) The product is easy to transport.
Disadvantages: (1) The effect of repelling mosquitoes is unstable. The first 4 hours are better. After 4 hours, the effect of repelling mosquitoes gradually decreases; (2) Insecticide formula cannot be adjusted at will, single insecticide formula is easy to adapt to mosquitoes; (3) Paper long-term Under fixed heating, the decomposition rate of insecticides is high; (4) The used paper still has 20-30% insecticide residues, which loses the effect of repelling mosquitoes, causing waste and polluting the environment.
3. Electric heating liquid mosquito coil
Advantages: (1) No smoke, no peculiar smell, no ash, no pollution; (2) Safe to use PTC heating source; (3) Use time as you like, power on when in use, and power off when not in use, it is very convenient to use. One bottle of medicament can be used continuously for about 300h (affected by PCT temperature); (4) It can be produced without mechanical equipment.
Disadvantages: (1) Due to the inconsistency of the boiling point and vapor pressure of the ingredients in the medicament, they cannot evaporate simultaneously during heating, causing the core rod to block. Therefore, the evaporation of the medicament gradually decreases with the increase of use time, and the effectiveness of repelling mosquitoes also decreases; (2) The formulation of the medicament cannot be adjusted at will, and the mosquitoes of a single formula are easy to adapt; (3) The decomposition rate of the insecticide is about 30-35% during use. After use, there are 5%-10% insecticidal residues on the mandrel. These losses , All greatly reduce the utilization rate of pesticides, cause waste, and pollute the environment; (4) The solvent is deodorized kerosene, and the medicine bottle is difficult to seal and leaks. Kerosene is dangerous and inconvenient to transport.
