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
This is the rare botanical pick we can stand behind, a recommended with caveats 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, enough for a hike or an evening out before you reapply, though tick coverage is much weaker at 0.5 to 2 hours. 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. Safety is the high point, though OLE carries a moderate irritation risk at this 30% load and the formula is not recommended for children under 3, a real limitation for families. What costs it most is the usual missing inert disclosure, which holds transparency back.

Effectiveness45%81Mosquitoes: 4–6 h of complete protection. Ticks: 0.5–2 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 ~4 h as repellency decays.
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.
“Oil of Lemon Eucalyptus 30%”
EfficacyStrongActive ingredient concentration confirmed by EPA registration and product label.
“Repels mosquitoes for up to 6 hours”
DurationStrongEPA label-approved protection time, confirmed in the EPA repellent search tool.
How to apply it
Apply to exposed skin and clothing; for best results, spread evenly with your hand to moisten all exposed skin. Do not spray directly on the face — dispense onto the palm of your hand and spread on the face and neck, avoiding eyes. Reapply once as needed, but do not apply more than twice per day. Do not use on children under 3 years old, do not allow children to apply it themselves or apply it to their hands, and wash the product from all exposed skin after returning indoors.
