DEET
DEET, chemically N,N-diethyl-meta-toluamide, is one of the most widely used insect repellents, applied to skin and clothing to deter mosquitoes and ticks. It is a synthetic compound registered as a pesticide rather than a cleaning ingredient, and consumers in adjacent categories often ask about it. This page is a neutral reference covering what DEET is, how it works, and how it is regulated.
