Peppermint, Rosemary, Garlic, Clove, Eucalyptus, Basil(lemon and cinnamon varieties work best), Lavender, Citronella Grass, Lemon Balm (often called Horse Mint), Marigolds, Catnip, Ageratum(often called Floss Flowers), Rose Geranium.
Suggestions on usage:
Peppermint-Make an infusion or an extract with vodka and a few of the leaves to use as a mist.
Rosemary-Best just grown and kept near your outdoor seating or activities.
Garlic-Even just eating more garlic in your diet can help as a repellant. (How you'll smell is a different story, hahaha!)
Clove-My suggestion is to put the whole cloves into an orange near where you'll be. (The smell is just like Christmas, all year long!)
Eucalyptus-My least favorite of all the smells...just sayin'. Can be grown near the needed area.
Basil-So many ways and uses! Great for growing for Italian foods AND repelling the mosquitoes. Who knew? The Lemon and cinnamon varieties of basil do work best as repellants. You can also rub the leaves right onto your skin.
Lavender-Just grow it near. I am sure it smells heavenly too.
Citronella Grass-Just like the name implies, it's where the oil in the stores comes from but, growing it yourself won't have all those crazy additives!
Lemon Balm (often called Horsemint)-I have found very little info on this but, I am guessing it smells good and is easily grown.
Marigolds-So pretty and a distinct smell. Grow them in pots, everywhere you can. Said to be HIGHLY effective in repelling not only mosquitoes but, deer won't eat them.
Catnip-So, in suggesting this I know I'll get some "if's, and's + but's"...Bring on every stray in the neighborhood. Just know that it's said to be 10X more effective than Deet! (WOWZA!)
Ageratum (often called Floss Flowers)-These often grow in the wild but, can be found at more selective stores.
Rose Geranium-The most commonly used repellant in South Africa. In researching all the above I learned these are quite the unique flower!
I suggested above about the Peppermint being made into an extract with vodka. SO many of the others above listed can be made into extracts also! Vodka is also a repellant so, have that martini while on the deck (please be responsible with it though, LOL!)
Best of luck and thank you for reading-
