Novel topical repellents for biting insects

A series of novel topical repellents for biting insects has been developed. These repellent molecules are based on naturally occurring chemicals produced by plants, and which are closely related to common flavor or fragrance ingredients. They have low toxicity, low odor profiles, and low volatility, making them desirable alternatives to more traditional repellents like DEET® and para-Menthane-3,-8-diol (PMD).
