In a group I help run I posted about a natural bug (and arachnid) repellent I was making for our porch and patio today. It was essentially half my essential oils and a stick of cinnamon I soaked in a half and half vinegar/water mix. There are many different oils and herbs one could procure to help ward off a variety of bugs without chemicals.
Some of these include:
*Mint (any kind)
*Citrus – Lemon, Lime, Orange, Grapefruit, etc.
I usually do a mix of what I have on hand to ward off different types of bugs but if you have a specific pest you can easily find specific herb/s for them.
After I have made my repellent I either add a cup to a gallon of water and wash the porch with it or I put it in a spray bottle and spray around door and window frames, etc. I would avoid getting this near your plants. If you have children or animals I would spray where they can’t lick or touch it and/or use only safe ingredients that won’t harm them if accidentally consumed.
If I’m making something for the skin I use half witch hazel instead of vinegar and put it in a spray bottle. Be careful not to spray too close to clothing as it can stain. Spraying on shoes or socks before a hike is helpful.
Alternatively, you can add a 2% dilution of these oils to body lotion and do a rest patch to make sure you are not allergic. Please look into the properties of the oils before attempting this. I am just giving suggestions as a place to start researching.
Here is a basic bug repellent I used to make:
Witch Hazel soaked in fresh Geranium and Marigold (then strained!), Spring Water, Essential Oils of Lavender, Peppermint, Lemongrass, Eucalyptus, Tea Tree and Citronella.
I don’t have the exact amounts as I do things as I go without recipes half the time. I would still make a 2% dilution of the oils. The herbs should be soaked 1-2 weeks. Dried works as well.
