Alternatives to DEET


The Centers for Disease Control (CDC) recommends the use of products containing active ingredients registered with the U.S. Environmental Protection Agency (EPA) for use as repellents applied to skin and clothing.

EPA registration of repellent active ingredients indicates the materials have been reviewed and approved for efficacy and human safety when applied according to the instructions on the label.

These products are sold at most major supermarkets and retailers throughout Boulder County.


The DEET alternatives listed below have been shown to have the same efficacy as a low concentration of DEET, lasting about 90 minutes.

Please follow the manufacturer’s instructions provided on the product label.
