Are Natural Mosquito Repellents Really Effective?

Natural mosquito repellent, like for example essential oils like citronella, eucalyptus, lavender, or lemongrass, are some favorite options people use instead of the chemical mosquito repellent! These organic alternatives can give you some temporary protection (by blocking out human odors, which the mosquitoes want to feed on), but tend to not work quite as well, or last as long, as repellents with DEET or picaridin.

The secret to using natural repellents is correct application and regularity. Most naturals need to be reapplied in 1-2 hours, even if you are indoor to have a moderate level of protection. Natural repellents can also be used together, mixing together with topical oils, diffusers, and candles, which can increase the efficacy, but might still fall short of stronger chemical repellents.

For complete mosquito defense, use natural repellents in conjunction with other methods. Source reduction, mesh on doors and windows, insecticide treated bed nets, and long sleeves and long pants when outdoors help to prevent exposure to mosquitos. When used carefully, natural repellents can offer some protection, though primarily for relatively brief periods spent outside, or for people who would react poorly to chemicals.
