Synopsis

Source of validity: Traditional
Rating (out of 5): 2

Fir (referring generally to species in the genus Abies) has a traditional use as an insect repellent, particularly in folk practices in North America and Europe. The needles, branches, or essential oil of fir trees have been used to ward off insects when placed in bedding, clothing storage, or burned as incense. This practice is documented in ethnobotanical records and traditional knowledge, where fir was valued for its aromatic properties that were thought to deter insects such as moths and mosquitoes.

However, while this traditional use is well-documented, robust scientific validation is limited. Some studies have noted that essential oils from various conifers—including fir—contain volatile compounds (such as bornyl acetate, limonene, and camphene) that show mild insecticidal or repellent effects in laboratory settings. Despite this, fir is less studied than other conifers like pine or cedar for this purpose, and there is a lack of comprehensive clinical or field studies confirming its efficacy as an insect repellent in real-world settings. Thus, the use of fir for this purpose is primarily justified by tradition rather than by strong scientific evidence.
