Active ingredients in Murphy's Naturals products
Citronella oil 0.2%–1.5%
In 3 of 5 products
The scent most people picture as bug spray, and one of the shortest-lasting actives in testing: roughly 15 to 20 minutes of full protection at the concentrations products use.
Lemongrass oil 2.3%–3.25%
In 2 of 5 products
Distilled from Cymbopogon citratus and dominated by citral, the aldehyde behind both its lemon scent and most of its bite. Among essential oils it is one of the stronger mosquito performers, giving roughly an hour to…

Peppermint oil 1.4%–2%
In 2 of 5 products

In 1 of 5 products
Botanical repellent derived from Corymbia citriodora. PMD (p-menthane-3,8-diol) is the primary active component in many products.
Castor oil 10.5%
In 1 of 5 products
Listed as an inert ingredient permitted in EPA minimum risk (FIFRA 25(b)) pesticide products.
