Repellants are materials that affect insects and other organisms by disrupting their natural behavior of bloodseeking through biting of humans and animals, and are the first line of defense that can be readily used for this purpose. Newer, chemically appealing formulations of chemical repellants have become popular in the United States since the mid-1980s, and interest in personal protection against biting arthropods has been renewed. The use of insecticides has led to the rise of widespread resistance in areas where residual insecticides were applied for malaria eradication and in some locations that have widespread irrigation, as in California, or that practice flooding for rice production.
