You can make a tea where you boil the herb in water. Once the tea has cooled, you can spray the tea in the area you need to repel insects. You can also keep live herb plants around the house and garden. When planting herbs to repel insects in the garden, you want to mix it up. Instead of clumping all your herbs into one pot or area, plant them around your vegetables and flowers you want to protect.
