A way to become less attractive to mosquitoes is to wear a commercially available, proven mosquito repellent. The District follows the Center for Disease Control recommendations on repellent.
CDC evaluation of information contained in peer-reviewed scientific literature and data available from EPA has identified several EPA registered products that provide repellent activity sufficient to help people avoid the bites of mosquitoes. Products containing these active ingredients typically provide reasonably long-lasting protection:
DEET (Chemical Name: N,N-diethyl-m-toluamide or N,N-diethly-3-methyl-benzamide)
Picaridin (KBR 3023, Chemical Name: 2-(2-hydroxyethyl)-1-piperidinecarboxylic acid 1-methylpropyl ester )
Oil of Lemon Eucalyptus* or PMD (Chemical Name: para-Menthane-3,8-diol) the synthesized version of oil of lemon eucalyptus
IR3535 (Chemical Name: 3-[N-Butyl-N-acetyl]-aminopropionic acid, ethyl ester)
EPA characterizes the active ingredients DEET and Picaridin as â€œconventional repellentsâ€? and Oil of Lemon Eucalyptus, PMD, and IR3535 as â€œbiopesticide repellentsâ€?, which are derived from natural materials.
