Head to head
Picaridin vs oil of lemon eucalyptus (OLE)
Picaridin tops our rankings; oil of lemon eucalyptus is the one plant-derived active that lasts hours, not minutes. The best synthetic against the best botanical, on duration, tick coverage, and the toddler rule.
We make Notch, so we're not a neutral third party. Rankings come from our published methodology, applied by code to every product the same way.
The bottom line
Choose picaridin for the longest protection and real tick coverage. Choose OLE/PMD when plant-derived sourcing matters to you and ticks aren't the threat. Just never use it on children under 3, and plan to reapply more often.

Head-to-head scorecard
Picaridin 20%
5 wins
Oil of lemon eucalyptus 30%
1 win
Picaridin nearly doubles the window from a single application, at a lower dose.
This is the real gap: OLE's tick performance is brief and unreliable.
OLE's whole appeal: the only botanical active with hours of real protection.
OLE carries a hard pediatric restriction; picaridin only the universal under-2-months rule.
How long each one lasts
Complete mosquito protection, by active ingredient
Hours until the first bite gets through, at typical consumer concentrations. Dark = lower bound, light = upper bound.
Modeled from complete-protection-time studies in our research library. Botanical bands reflect 10% lab-tested concentrations. Most consumer botanical products use less and protect for less time.
Does a higher percentage mean more protection?
Complete mosquito protection at each tested concentration. Dark = lower bound, light = upper bound.
Picaridin
Oil of lemon eucalyptus
Concentration can't close the gap. Even at 30%, OLE lands around where 10% picaridin starts, and picaridin's curve keeps climbing to 8–10 hours at 20%. OLE needs roughly three times the dose to reach a mid-range synthetic's duration, and still can't catch full-strength picaridin. Same 12 h scale used across the site; modeled from dose-response data in our research library.
Picaridin 20%
Longest-lasting consumer option; odorless and gentle on gear.
Oil of Lemon Eucalyptus (PMD) 30%
The plant-derived active with DEET-class mosquito protection. Not for children under 3.
Which should you pick?
Choose Picaridin if…
- You want the longest protection from a single application
- You're in tick country, where OLE's coverage falls short
- It's going on young kids (over 2 months) or the whole family
- You'd rather not reapply every few hours
- Odorless and non-greasy matter to you
Choose Oil of lemon eucalyptus if…
- Plant-derived sourcing is the deciding factor for you
- Mosquitoes, not ticks, are the threat you're dressing for
- You're fine reapplying every 4–6 hours
- No one under age 3 will be wearing it
Frequently asked questions
Is oil of lemon eucalyptus as effective as picaridin?
Against mosquitoes it's in the same league for a shorter window (4–6 h vs 8–12 h). Against ticks it is not: OLE's tick protection is weak and brief, while 20% picaridin holds 7–8 hours.
Can children use oil of lemon eucalyptus?
Not under age 3. Picaridin has no such restriction beyond the universal 'no repellent under 2 months' rule, which makes it the easier family choice.
