The Best Insect Repellent Essential Oils ToKeep Bugs Away
If you are confused by all the conflictinginformation regarding the most effective essential oils to use as insectrepellants, you may find the opinions of two respected entomologists(scientists who study insects) highly enlightening.
In a recent article, the entomologistsseparated fact from fiction and identified the most effective ways to keepthose pesky biting bugs at bay.
Dr. Richard Pollack, an entomologist atHarvard University, and Joseph M. Conlon, a retired Navy entomologist who isnow an advisor to the American Mosquito Control Association were bothinterviewed by Today.com. Their comments make very interesting reading for bothhome enthusiast and qualified aromatherapist.
As well as debunking some of the common mythsthat are found all over the internet, these experts unequivocally confirm whataromatherapists have been preaching for years; certain essential oils areeffective at keeping mosquitoes and other biting bugs at bay.
You only have to spend a few seconds on theinternet searching for ‘the best insect repellent essential oils’ and you willreturn about half a million search results. Drill down into these and you willfind just about as many opinions as to the most effective essential oils torepel the bugs! The problem is that virtually none of the information on thesesites comes from experts in their field. That’s what makes the opinions ofthese entomologists so important.
Essential oils are natures very own ‘insectrepellents’, produced by flowers and plants as a self defence mechanism againstwould-be predators. Millions of years ago plants evolved tiny oil producingglands within the leaves to avoid being eaten alive by insects, and theirsurvival shows it’s been a highly effective strategy. The challenge today hasbeen identifying which are the most effective insect repellent essential oils.
So here are the essential oils that thebug-loving experts agree have demonstrated insect repellent activity:-
Cedarwood (Cedrus atlantica)
Citronella (Cymbopogon nardus)
Lemon Eucalyptus (Eucalyptus citriodora)
Lemongrass (Cymbopogon citratus)
Rosemary (Rosmarinus officinalis)
Interestingly, in trials I found thatlemongrass and citronella oils performed equally well and could be usedinterchangeably in formulations. In fact, for over 10 years I switched betweenthe two as the principal active ingredient in our insect repellent products. Ieventually settled on citronella oil because, since ancient times wherever theplant grew and mosquitoes were prevalent, the grass would be utilised to helpkeep them at bay. It just felt right to keep with the traditional use.
Citronella essential oil
Citronella essential oil is known to be astrong inhibitor of Streptococcus pneumoniae,which apart from being responsible for pneumonia also causes meningitis, septicarthritis, peritonitis, osteomyelitis and brain abscesses. Similarly, it isquite effective in inhibiting a wide range of human pathogenic fungi, including Candidaalbicans, Aspergillus niger, Sporothrix schenckii and M. gypseum.
This antibacterial and antiviral action makescitronella oil extremely useful in treating colds, flu and other bacterialinfections, and when used in massage it effectively eases arthritis, neuralgia,rheumatism and all types of aching muscles.
When used in skin care citronella essentialoil can help with excessively oily skin, and in the same way it conditions andbalances greasy hair too. Included in personal care products, citronella helpsto reduce excessive perspiration, particularly when blended with cypress oil.On the nervous system, citronella oil is uplifting, refreshing and cleansing,which makes it helpful with lethargy and more severe emotional conditions suchas anxiety, stress and tension.
In aromatherapy, citronella essential oil canbe used as a middle to top note when blending with other oils; try it withbergamot, cedarwood virginian, cedarwood atlas, cypress, fir silver,frankincense, geranium lavender, lemon, orange bitter, pine, sandalwood andvetiver.
For extra protection against a wider range ofbugs, mix citronella essential oil with eucalyptus citriodora, lemongrass andcedarwood atlas, since these oils also offer protection against several speciesof flying beasties.
