　　5. How do households control mosquitoes?

　　Physical and chemical methods can be used to control mosquitoes in households. While removing stagnant water, installing screen doors and windows, and killing mosquitoes, mosquito incense and insecticidal aerosol can be used to control mosquitoes and mosquito larvae can be used to treat stagnant water that cannot be removed.

　　Additional screen doors and windows: The room can install screen doors and windows to prevent mosquitoes from driving straight in. In the high incidence period, the screen windows can be smeared with residual spraying insecticides, and the effect is better. Use mosquito nets during rest to reduce human mosquito contact.

　　Clean up breeding areas: household vases and aquatic plants should be thoroughly changed at least once a week. Air-conditioning trays, flower pot underpans (trays) should be thoroughly cleaned up and covered. Weekly inspection of bathroom and kitchen floor leaks or replacement of safe floor leaks with anti-seepage functions, keep the floor leaks free of water, and often spray insecticides, do not give mosquitoes living space, garbage cans should be covered.

　　6. How do enterprises, institutions and communities control mosquitoes?

　　The treatment of breeding sites is an important basis for mosquito control, and a patriotic public health campaign to eliminate mosquito breeding sites needs to be extensively carried out. On the basis of comprehensive control of breeding areas, rational use of various biological and chemical pesticides.

　　Removal of breeding grounds: Mainly include removal of various waste and debris, thorough cleaning of bottles, buckets, water basins and other containers that may accumulate water before and after the house, inverted storage of empty containers to prevent mosquito breeding. The outdoor landscape waters of various communities, such as bonsai, fountain, fish pond and so on, should be cleaned up of garbage floats in an all-round way, and water should be changed frequently. We should regularly dredge the ditches and sand wells in the community, keep the drainage ditches free of water, seal the wells, use mosquito-proof stickers for the cover of the wells, check the basement regularly, remove the water in time, and prevent mosquito breeding. Regular dredging of drainage holes and pipes in roofs and other places of residential buildings should be carried out in time to avoid water accumulation after rain.

　　Biological control: Large water bodies such as fountains and pools that can not be discharged can be treated with biological mosquito control methods. Fish species such as wicker, goldfish, carp, carp, crucian carp, Chinese betta, African crucian carp, which can swallow mosquito larvae, can be reared to achieve the purpose of mosquito control. Biological mosquito-killing larvae such as Bacillus thuringiensis or Bacillus sphaericus can also be used.

　　Chemical control: Under the guidance of professional technicians, detention spraying is carried out on key parts to kill adult mosquitoes. For outdoor landscape waters such as water wells, sewers and fountains that can not be sealed, mosquito larvae can be killed by insecticide larvae. In the places where the adult mosquito density is relatively high, the ultra low volume spray or hot smoke can be used for space spraying treatment at the peak time of adult mosquito killing.

　　7. How to avoid mosquito bites when traveling?
