Essential oils and aromatherapy make excellent natural insect repellents as they are not chemically based and are not toxic for humans, animals and/or insects. Instead, natural insect repellents made from Essential oils and aromatherapy blends deter insects and creepy crawlies from entering our homes and living spaces, rather than killing them.
Insects react to the scent and composition of the essential oils and will avoid them whenever possible.
The essential oils that work best against biting insects (mosquitoes, flies, ticks, fleas) are:
Cinnamon oil (for mosquitoes)
Lemon Eucalyptus or regular Eucalyptus oil (mosquitoes, ticks, and lice)
Citronella oil (mosquitoes and biting flies)
Castor oil (mosquitoes)
Orange oil (fleas)
Rose Geranium (ticks and lice)
Another plant-derived substance, pyrethrum, is an insecticide. Pyrethrum comes from the flowers of the daisy Chrysanthemum cinerariifolium.
