DDT is out. But what is in?
If you are as old as we are, you probably remember when DDT was touted as the end to all of your bug problems. Then we discovered that the cure was perhaps worse than the disease. A short review will help you understand why.
DDT (dichloro-diphenyl-trichloroethane) was developed as the first of the modern synthetic insecticides in the 1940s. It was initially used with great effect to combat malaria, typhus, and the other insect-borne human diseases among both military and civilian populations. It also was effective for insect control in crop and livestock production, institutions, homes, and gardens. DDT's quick success as a pesticide and broad use in the United States and other countries led to the development of resistance by many insect pest species.
The U.S. Department of Agriculture, the federal agency with responsibility for regulating pesticides before the formation of the U.S. Environmental Protection Agency in 1970, began regulatory actions in the late 1950s and 1960s to prohibit many of DDT's uses because of mounting evidence of the pesticide's declining benefits and environmental and toxicological effects. The publication in 1962 of Rachel Carson's Silent Spring stimulated widespread public concern over the dangers of improper pesticide use and the need for better pesticide controls.
In 1972, EPA issued a cancellation order for DDT based on its adverse environmental effects, such as those to wildlife, as well as its potential human health risks. Since then, studies have continued, and a relationship between DDT exposure and reproductive effects in humans is suspected, based on studies in animals. In addition, some animals exposed to DDT in studies developed liver tumors. As a result, today, DDT is classified as a probable human carcinogen by U.S. and international authorities.
Since 1996, EPA has been actively participating in international efforts to control the use of DDT and other persistent organic pollutants used around the world. DDT is one of 12 pesticides recommended by the World Health Organization for indoor residual spray programs, particularly for use in African countries where malaria remains a major human health problem. It is up to individual countries to decide whether to use DDT. EPA works with other agencies and countries to advise them on how DDT programs are developed and monitored, with the goal that DDT be used only within the context of Integrated Vector Management (IVM). IVM is a decision-making process for using resources to yield the best possible results in vector control and keep DDT out of agricultural sectors.
Most recently, the emphasis has been on natural pest control. As a result, the following are several DIY pest control recipes that you may find beneficial in helping with your pest control issues.
