Later, the U.S. government applied for its use in wartime, especially in Vietnam and Southeast Asia. According to the statistics of the U.S. Environmental Protection Agency, nearly 40% of Americans use insect repellent containing DEET every year, which has been used by about 200 million people around the world for more than 40 years, Studies by more than 20000 research units have proved that DEET is the safest and most effective broad-spectrum repellent on the market.
