Dengue fever is currently spreading in many areas. Therefore, spraying mosquito repellent is a very necessary and important issue to limit the spread of the disease and a wider outbreak. However, spraying mosquito repellent has appeared in some families where people are allergic to mosquito repellent.

To effectively prevent dengue fever, one of the effective measures is to spray insecticides to kill mosquitoes. Current mosquito repellent spray is a drug that has been tested for safety results, fully meeting the quality criteria approved by the Ministry of Health for use.
The spraying is done for free, people do not have to pay any money. Technically, spraying is spraying with a very small amount of chemical in the form of a mist, but with maximum effectiveness. Only a few hours after spraying, the amount of chemicals will diffuse in the space, so the concern about the drug affecting health and mosquito allergy is insignificant.
Because of the characteristic that only a few hours after spraying, this amount of chemical is diffused in space, so the spray can only kill adult mosquitoes infected with dengue virus at the time of spraying, but not for a long time, forever. Therefore, when the amount of chemicals has been exhausted in the air, if the surrounding environment or other households still have mosquitoes carrying dengue fever, these mosquitoes can still continue to fly into the house and bite people. And so, the risk of dengue fever still occurs.
Therefore, spraying insecticides to prevent dengue fever needs to be done on a large scale.
