Can act as a natural insect repellent

Because of its eucalyptol concentration, eucalyptus oil is a natural insect repellant. According to studies, it is efficient at repelling mosquitoes and other biting insects for up to eight hours after topical application. The more eucalyptol there is in eucalyptus oil, the longer and more efficiently it functions as a repellent.

In reality, the Centers for Disease Control and Prevention identifies lemon eucalyptus oil, which is produced from the lemon eucalyptus tree, as a safe and effective insect repellent. Eucalyptus oil may also be used to treat head lice. This oil was twice as effective as a common head lice treatment at curing head lice in one randomized research. A new assessment, however, recommends that further research is required.
