However, the protection offered by lemon eucalyptus oil doesn’t seem to last quite as long as DEET.
Preventing tick bites, when applied to the skin. Applying a specific 30% lemon eucalyptus oil extract three times daily significantly decreases the number of tick attachments experienced by people who live in tick-infested areas.
