Fogging is one of the most commonly used methods for eradicating dengue dengue mosquitoes (DBD). In this method, a location is sprayed with insecticide using a machine.
Fogging in this particular dose is aimed at eradicating adult mosquitoes, or who have been able to fly. However, the current fogging method is questioned its effectiveness. This is because cases of dengue fever tend to increase.
To prevent the increase in cases and the increasing number of DHF victims, here I will share tips for effective fogging efforts. In order for maximum fogging results, there are several things to watch out for.

Minimum 100 meters radius#
Fogging should also be done within 100 meters around the dwelling place of DHF patients. This is because, 100 meters is the optimal distance for dengue mosquitoes to move places. Houses within a 100-meter radius have a high chance of getting dengue virus. A 100-meter radius is a condition where there is only one victim. If the victim has more than 3 meals the radius increases by more than 100 meters.

Note the dose#
Spraying should take into account the doses recorded in the operational standard. If the insecticide is too little, then spraying does not give maximum results and leave only the smell of kerosene that interfere with comfort. Appropriate dose is also feared to make insecticide resistant mosquitoes.

Keep an eye on the wind#
Wind direction often escapes attention. Though the wind will spread the insecticide spray throughout the region, within a certain radius. Winds also carry mosquitoes to move to avoid pesticides.
Fogging causes insecticide droplets and is lethal for adult mosquitoes that are in direct contact. When removed from the spraying machine, the mist of the insecticide will immediately spread in the direction of the wind. Therefore, spraying should be done in the direction of the wind. Spraying against the wind will affect the body of the sprayer instead of the targeted mosquitoes. As a result insecticides will be toxic to sprayers.
