Oil of Lemon Eucalyptus (or PMD) is a natural, plant-based repellent derived from the oil of the leaves of the Eucalyptus citidora tree. Repellents containing the oil of lemon eucalyptus provide similar protection to those with low concentrations of DEET. These products tend to have a strong botanical smell and are available in a wide variety of formulations, including pump sprays and lotions.

DEET–based repellents are the most effective and best-studied repellents available. In fact, they've provided effective and dependable protection since the 1950s. Available in different concentrations (which all repel insects equally well for the length of time they are needed), DEET repellents come in a variety of forms, including aerosol and pump sprays, as well as wipes. 

Not a fan of DEET? Don’t worry you have options!
