Rating (out of 5): 3

Terpinolene is a naturally occurring monoterpene found in a variety of plants, including conifers and some herbs. There is scientific evidence supporting its use as an insect repellent. Several laboratory studies have demonstrated that terpinolene exhibits repellent activity against mosquitoes and other insects. For example, research published in peer-reviewed journals has shown that terpinolene, either alone or as a component of essential oils (such as tea tree or pine oil), can deter mosquito landings and bites. The mechanism is believed to involve its volatile aroma, which interferes with the insects’ olfactory receptors.

While terpinolene is not as extensively studied or as potent as established repellents like DEET or even some other plant-derived compounds (e.g., citronellal or limonene), its inclusion in essential oil blends for insect repellent purposes is supported by scientific literature. However, most studies have been conducted in vitro or in controlled laboratory settings, and fewer have assessed its effectiveness in real-world conditions or in commercial formulations. Thus, the evidence is moderate but not robust, warranting a rating of 3 out of 5.

Overall, terpinolene has a basis in scientific research as a mild insect repellent, but more studies are needed to confirm its efficacy and safety in practical applications.
