Essential Oils and Pest-Control Claims

Start with the pest and setting, then examine the product label and the evidence behind a repellency or control claim.

Choose the question you need to answer

If you have an active pest problem, identify the pest and affected area first; use an appropriate pest-control professional when identification or control is uncertain. If you are evaluating a product, find its exact label and applicable registration or exemption information. “Contains peppermint” does not tell you which pests, locations, or uses the product covers.

Read results in context

A laboratory observation that insects move away from a scent is different from evidence that a product controls an infestation in a home. Look for the species, formulation, setting, duration, and measured result. The pages below help you examine those differences; they do not supply homemade pesticide recipes.
