Retailer links may earn us a commission. Scores are never affected.
Pros
- The strongest plant-based option, 30% lemon eucalyptus for 4 to 6 hours, with real published evidence.
- Fully disclosed and EPA-registered, a credible DEET-free choice.
Cons
- Weak on ticks and carries a strong eucalyptus scent.
- Not recommended for children under 3.
The full review
Here is the rare botanical worth standing behind, a recommended built on 30% oil of lemon eucalyptus, the one plant active with real published, CDC-recognized field evidence. Our model puts complete mosquito protection at a respectable 4 to 6 hours and tick protection at 3 to 5 hours, enough for a hike or an evening out before you reapply. The evidence pillar is good, if not quite DEET-level, with 6 of 7 claims strong, and the formula is EPA-registered and fully disclosed at the active. Safety is a high point, though OLE carries a moderate irritation risk at this 30% load and the formula is not for children under 3, a real limitation for families. What costs it most is the missing inert disclosure, which holds transparency back.

Effectiveness45%92Mosquitoes: 4–6 h of complete protection. Ticks: 3–5 h of complete protection. Protection times are modeled from the actives, concentration, and format (see methodology). Scored on a saturating curve (each added hour counts less than the last), 65% mosquito / 35% tick, with reasonable confidence.

How long it protects
Complete protection ends when the first bite gets through; partial protection keeps reducing bites as repellency decays. EPA label times are verified; the rest are modeled from the actives, concentration, and format.
Mosquito estimate basis (moderate confidence)
Estimated complete protection time from active ingredient + concentration; the source research used a spray-style formulation, matching this spray (no format adjustment). Partial protection (reduced but real bite suppression) is modeled to extend to ~11 h as repellency decays.
Tick estimate basis (moderate confidence)
Estimated complete protection time from active ingredient + concentration; the source research used a spray-style formulation, matching this spray (no format adjustment). Partial protection (reduced but real bite suppression) is modeled to extend to ~9 h as repellency decays. OLE/PMD is shorter-lasting and more species-variable against ticks than mosquitoes. Deer-tick CPT runs ~2.7 h (EWG pooled) to ~4.8 h at 30% (Citrefine/ARCTEC, sponsor-reported); it lasts longer against the lone star and brown dog ticks.
Ingredient disclosure
This product publishes an ingredient list (+20); discloses 100% of active concentrations (+40); discloses 100% of all ingredient concentrations (+15); inert ingredients are not fully accounted for (0).
Only active ingredients are disclosed. The full ingredient list (inerts/carriers) is not published, so this may not be the complete formula.

Claims audit
What the marketing says, versus what the evidence supports.
“Provides protection similar to repellents with 15%-20% DEET”
EfficacyStrongOLE at 30% gives a 4–6 h estimate, matching 15–20% DEET (~4–5 h), so this specific equivalence is consistent with our own protection data.
“Developed for family adventurers — not to be used on children under 3 years”
Kid SafeModerateReplaces the previous 'safe for the whole family' phrasing: the label explicitly prohibits use on children under 3, consistent with CDC guidance for OLE products.
“Plant-based active ingredient”
NaturalStrongOLE/PMD is derived from the lemon eucalyptus plant and the wording 'plant-based active ingredient' stays factual.
“Repels mosquitoes that may transmit Zika, West Nile, Dengue and Chikungunya viruses”
EfficacyStrongEPA-registered label claim; repellency does not guarantee disease prevention.
“DEET-free formula (*not a safety claim)”
Deet FreeStrongAccurate; the label itself notes DEET-free is not a safety claim.
“Repels mosquitoes for up to 6 hours”
DurationStrongConsistent with our complete-protection estimate (~6 h).
“Oil of Lemon Eucalyptus 30%”
EfficacyStrongActive ingredient concentration confirmed by EPA registration and product label.
