Hello, and thanks for any and all information. Recent studies have clearly shown Lemon Eucalyptus (Eucalyptus citriodora) to be more effective than DEET as an insect repellant. The oil is very inexpensive. I would like to know what I can use as a carrier/dilutant to apply it to one's body (there is already a commercial version on the market, so it can be done), and also what I can use to dilute it for spraying. I can get the oil for under $40 for 5#, and I thought I would simply spray every few days around the area where we sit outside. Thanks.
