Study 1:
A scientific review assessed plant‑derived repellents, including PMD from lemon eucalyptus. The review observed that PMD provided longer‑lasting mosquito repellency compared with many volatile plant oils in controlled studies.
Study 2:
A review article described PMD derived from lemon eucalyptus as a botanical mosquito repellent. Observations summarized its performance against multiple mosquito species in controlled testing.
Study 3:
A field trial evaluated lemon eucalyptus extract (Citriodiol) applied to human skin in tick‑infested areas. The study observed associations with fewer ticks attaching to treated skin compared with untreated controls.
Study 4:
A laboratory bioassay evaluated multiple essential oils for repellency against mosquitoes and ticks; lemon eucalyptus extract was included among the oils tested. Associations were observed with differences in repellent activity under controlled conditions.
