Mosquito Coils
Mosquito coils are a type of incense that contain mosquito-repelling ingredients. They first appeared in the late 1800s and are designed in a spiral shape that burns for about 7-12 hours.
The main ingredients include dried pyrethrum, a natural insecticide derived from chrysanthemum flowers, and synthetic pyrethroids, along with the antioxidant additive Butylated Hydroxytoluene (BHT) to prevent oxidation during burning.
Mosquito Sprays
Mosquito sprays are liquid insecticides packaged in aerosol cans and were first developed in 1946, gaining popularity in 1957. The active ingredient is typically a synthetic chemical, with some brands using natural alternatives, and the concentration usually ranges from 24% to 30%.
Higher concentrations mean longer-lasting effects, but they can also be more toxic. On average, mosquito sprays are most effective for about 5 to 8 hours after application.
