DRUG DRUG DRUGS TO PREVENT DISEASES OF DANGEROUS FEVER

hi steem, today when i come home from work, i meet someone who is spraying mosquito repellent (voging).
why should we spray the mosquito repellent? for lately many diseases that are caused by mosquitoes such as dengue fever. Dengue can cause death if we can not prevent it. so in the housing complex, janitors always spray mosquito repellent in every trench and trash can, spraying time at 5 pm to 6 pm.

in my area to prevent dengue fever there are in the name of 3M.
what is 3M? 3M is 1. drain the tub 2. bury the used goods 3. close the water reservoir.
let from dengue fever, and healthy life is important for all human beings.
