Have you used these mosquito killer products correctly?

Mosquito coils, lighting the mosquito coils before dark will provide the best mosquito repellent effect. In addition, the use time of electric mosquito coils should not exceed 8 hours. If in a closed room, mosquito coils can kill mosquitoes; in ventilated places, mosquito coils can play a role in repelling mosquitoes. Regarding the mosquito-repellent incense sheet (liquid) commonly used in residents’ homes, experts said that the mosquito-repellent incense sheet (liquid) contains insecticides. Although its toxicity is very low, direct contact should be minimized if it is touched. Wash your hands in time. When using in a closed and poorly ventilated room, pay attention to timely ventilation and do not use it for more than 8 hours at a time. And do not place it in a corner or under curtains, as this will affect the insecticidal effect. The elderly, patients, and people with allergies should use mosquito nets or other physical methods to prevent mosquitoes.

　　 In addition, electric mosquito coils (liquid) have a certain amount of effective mosquito repellent space. Excessive space or long use time will affect the mosquito repellent effect. The summer is sultry and the doors and windows of the room are mostly in a ventilated state. The mosquito coiler should be placed upwind to achieve a better killing effect.

When using insecticidal aerosol, try not to spray it directly on clothing, sheets, furniture, skin, and tableware. When the number of mosquitoes is not large, it is not recommended to use insecticidal aerosol. 　　 In addition, when using insecticidal aerosols, be careful to spray flying insects such as flies and mosquitoes in the air at an angle of 45°. After spraying, it is best to close the doors and windows for half an hour to an hour, and then open the windows for ventilation. Insecticidal aerosols are convenient to use, but overspraying will also have a certain degree of toxicity to the human body. Therefore, you must pay attention to safety when using insecticidal aerosols at home to prevent poisoning.

　　 Many people have a misconception that the smell of aerosol can smoke and kill mosquitoes, but in fact it can only kill mosquitoes (touch kill) when it comes in contact with the body of the mosquito. Simply spraying aerosols indoors and closing the doors and windows in the hope that the smell can kill the mosquitoes is not effective.
