To prevent the devastating disaster brought by mosquitoes, people have come up with several basic methods to restrain the spread of pathogens. The first is to prevent the mosquitoes from entering human colonies. The second is to directly eliminate the mosquitoes either by poisonous medicines or physical ways including beat and electric shocks. The third method utilizes chemicals to disturb the mosquitoes. Mosquitoes mainly identify the hosts by detecting the CO₂ released or by the amino acids that form the odor from animals or humans. Therefore, when the substance can produce smell that mosquitoes dislike, or can leak molecules that block the receptors of mosquitoes, the mosquitoes can be successfully repelled.[7]

Being aware of the potential for developing fire hazards, consumers have to be careful with using mosquito coils. Some studies highlight concerns when mosquito coils are used in closed rooms. Coils sold in China and Malaysia were found to produce as much smoke PM 2.5 as 75-137 burning cigarettes and formaldehyde emission levels in line with 51 burning cigarettes. [10] Moreover, smoke produced from coil combustion may cause sensory irritation of respiratory system.

Furthermore, if we overuse Floral water, it will harm our body for the ingredient DEET or BAAPE is actually poisonous.
