Summary
Arm-in-cage laboratory evaluation of a 25% geraniol commercial product (MosquitoSafe, mineral-oil base) against three mosquito species, versus 7% DEET.
Key findings
25% geraniol gave roughly 3–5 h of protection in cage tests (one of the better natural products), but the result is product- and vehicle-specific rather than a measure of geraniol the active.
Limitations
Only 2 volunteers per product; a single oily commercial formulation, not the molecule; lab-cage design overstates field protection; 2004-era methods. Superseded for ingredient-level conclusions by controlled dose-response studies.
