After the original studies for this article were completed,
a new botanical repellent was introduced in
the United States. The repellent contains oil of eucalyptus
and is marketed under two names: Repel
Lemon Eucalyptus Insect Repellent (WPC Brands) and Fite Bite Plant-Based Insect Repellent (Travel
Medicine). We evaluated this type of repellent using
the same testing methods in six subjects (five men and
one woman). In one subject, a localized cutaneous reaction
developed after the first test, and the subject
discontinued the study. All other subjects completed
three tests each of the repellent. The repellent had a
mean (±SD) complete-protection time of 120.1±44.8
minutes, with a range of 60 to 217 minutes.
