Natural Black Fly Repellents

Black fly season has come early this year thanks to the warm weather we’ve been enjoying. Traditional chemical repellents don’t do the trick and are full of harmful toxins, but there are some natural ways to beat back those little beasties.

Watch the video here or follow the recipes below;

Greenmoxie’s Shoo Fly! Black Fly Repellent Recipe

Mix 2 cups water with 1/4 cup of vinegar and 10 drops of spearmint, mint or peppermint essential oils. Spray pets, family members, strollers, clothing and around doors and windows.

Wear the right clothing

When in doubt, ask yourself: Would Indiana Jones wear this? Always opt for white, beige, khaki or other lightly colored clothing as biting bugs are attracted to dark hues.

A great way to prevent getting bitten is to cover up. If it’s very warm, opt for cool organic cottons and other breathable fabrics.

Minty Goodness

Mint, spearmint and peppermint are great deterrents for black flies. Growing your own mint is really easy. Add a couple of drops of DIY black fly bug spray recipeessential oil to your body lotion, to the final rinse of your laundry or just dab some on your clothing. Applying essential oils directly to skin may cause reactions or rashes.

You can also make a minty spray that combines not only a minty smell, but the power of vinegar too.

Lemon eucalyptus oil 

This product from down under is also a great way to keep those flies at bay. Dab some on clothing or add 10 to 15 drops to a cup of water in a bottle and spray the flies away. Other oils you can buy  include sassafras, pennyroyal, lavender, eucalyptus, lemon balm and cedar.

Notoriously itchy and achy, black fly bites are the pits. You can mitigate some of the discomfort by applying aloe vera or witch hazel to affected areas.

    Years ago there was a spray that my mother used to spray on the window screens and it would let the air in, but NOT the black flies (or here in VT we call them no see ems) looking for a recipe with essential oils that would work the same way.

      No-see-ums are not the same as black flies. black flies are much larger. We have both in Maine, and you have both in Vermont, and they are not the same–though just as pestiferous, and are related, but no-see-ums are in the family Ceratopogonidae and black flies are in the family Simuliidae, both in the Order Diptera.

    Vanilla extract works wonders for black flies, and lasts for hours. I just dampen a paper towel with water, pour on the vanilla (the real stuff) and wipe down. It lasts for hours and smell good too.

    I get eaten alive by black flies, mosquitoes anything that sucks your blood. I love to be outside but I suffer for it every time.
    Please help, I must have sweet blood because everyone else is bite free.

        Just a caution about using essential oils: Citrus oils can cause major sensitization in the sun. If you’re going to use any citrus oil, including orange, spray it on your clothing and not on your skin if you’ll be out in the sun.
