Are you looking for a good DIY flyspray that you can make at home? One that actually works? Look no further. This is made with mostly natural ingredients and is much less harsh on your skin/lungs/everything else it gets on.
4 cups apple cider vinegar (raw with the mother works best)
20 drops rosemary oil
20 drops basil oil
20 drops peppermint oil
2 tablespoons liquid oil (olive oil, canola oil, or mineral oil will work)
1 tablespoon dawn dish soap
Mix all of these ingredients in a spray bottle. And be sure to shake it well before each application to ensure the ingredients are fully mixed to be most effective.
There are lots of other essential oils that help ward away flies, so feel free to add those in and play around with the recipe to your liking. (lavender, tea tree, pine, citronella, lemon grass, etc.)
Something to keep in mind, is since this doesn’t contain all of those harsh ingredients, you will need to apply it more frequently. But it does work well if applied regularly.
