What is a "home remedy" not over the counter, to repel mosquitoes or flying insects?

Homemade Insect Repellent Recipe:

10-25 drops essential oil. (Lavender, rose geranium, coriander seeds, peppermint, cajeput and citronella are good choices)
2 tablespoons vegetable oil
1 tablespoon aloe vera gel (optional)
Combine the ingredients in a glass jar; stir to blend. Dab a few drops on your skin or clothing.

Some natural ways to repel mosquitoes can be found in plants. Planting citronella grass repels mosquitoes as well as planting marigolds. Try growing an herb garden with rosemary, basil, and lemon grass. Other plants that contain oils to repel mosquitoes are cedar, sagebrush, onion, garlic, eucalyptus, and peppermint.

The best way to prevent mosquitoes is to make sure there aren't any wet areas where the mosquitoes can lay eggs. It can be a stagnant pool or pond, or even a puddle in the yard. If you have a bird bath make sure to change the water often.
