What oils make the most effective insect repellants?
The CDC (Center for Disease Control) recommends only one essential oil as an effective mosquito repellant based on scientific research, lemon eucalyptus. However the EPA also acknowledges citronella as an effective repellent. Others oils have been used traditionally to discourage various insect pests including eucalyptus, lavender, peppermint (ants), cedarwood (moths) and juniper (fleas) and spike lavender (lice).
