It’s the time of year in tropical countries, when insects and rodents tend to be everywhere. We bear diseases which can be unpleasant or killing. Especially the children are susceptible. We enjoy playing outside without the noisy animals in mind. Occasionally, they also enjoy the business due to the acrobatics in the air of the sound and the bee.
One common practice is to use an insect repellant especially for children. The typical way to fend off such so-called pests is by using smoke. Some families will set some leaves and twigs on fire from plants that emit a certain odor that is toxic to mosquitoes when burned. This is the precursor of the fumigation method of spraying certain chemicals into an area that releases fumes that carry smells that repel the mosquitoes.
The katol or mosquito coil had been developed for indoor use. This Green Coil (originally) is burned like a cigarette. The smoke released repels the mosquitoes, as well. The katol is usually used in the bedroom and is intended to last for the user’s sleep, or around eight hours. Like cigarette, it leaves ashes that need to be swept up and disposed of in the morning.
Using lotions is one more modern approach. These are formulations which have been sprayed or rubbed onto the skin. Mosquitoes aren’t going to bite the person wearing the lotion because of the uninviting scent they sense when they approach. A chemical named DEET is a common ingredient in these lotions.
N , N-diethyl-meta-toluamide is short for DEET. It was initially developed after World War 2 by the United States Army for use in jungle warfare. This has been used in Vietnam and Southeast Asia. It was released in 1957, for civilian use.
In 1998, the U.S. Environmental Protection Agency issued a Registration Eligibility Decision stating that “DEET insect repellents will generally not cause unreasonable risks to humans or the environment as long as consumers follow label directions and take proper precautions.” The document contains labeling specifications including statements such as; do not use under clothing, use just enough r The document also specifies that statements about child-safe products should be removed from the labels.
