When did mosquito coils become a common insect repeller? Their origin dates back to the late 1800s in Japan when a businessman and his wife mixed pyrethrum, derived from chrysanthemums, with sawdust and fashioned it into its iconic coil shape to burn longer while keeping mosquitos and other biting insects away. Mass production of the coil repellents began in the 1950s, and they soon caught on in many countries, including the United States.
Today's mosquito coils still contain a form of dried pyrethrum powder along with citronella and other binding agents. When lit, the coils produce smoke that spreads outward to keep away flying pests.The smoke does not kill mosquitoes; instead, it discourages mosquitoes from hanging around. These coils are popular with the general public because they are portable, long-lasting and inexpensive.
ARE MOSQUITO COILS DANGEROUS?
Many studies have shown that the coils do not pose a health risk when used responsibly, although some experts have questioned these findings. The mosquito repellent coils themselves are not harmful to humans.
