Pros
- Built for tick country, 5 to 8 hours of tick cover and 5 on mosquitoes from 15% picaridin.
- Picaridin's light feel and gear-safe formula make it easy to wear all day.
Cons
No significant downsides for its role.
The full review
Built for tick country, this 15% picaridin pump spray lands a clear recommended. Picaridin rests on settled published evidence and reads clean on skin safety, without DEET's habit of damaging gear and synthetics. The tick framing holds up: our model puts complete protection at 5 to 8 hours against ticks and 5 to 7 against mosquitoes, and all 4 audited marketing claims hold up. The label's up to 5 hour figure measures reduced biting rather than bite-free time, so it sits comfortably alongside what we model. The only real drag is transparency, where the active is fully disclosed but the inert list is not, and its light feel makes it easy to wear all day.

Effectiveness45%96Mosquitoes: 5–7 h of complete protection. Ticks: 5–8 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 ~12 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 ~14 h as repellency decays. Buchel 2015: 10% picaridin tick CPT ~5 h (I. scapularis) to 8 h (I. ricinus), equal to or better than 20% DEET. Carroll 2010: 20% kept ticks off through the full 12 h test against the lone star tick; we cap at a defensible ~10 h.
Ingredient disclosure

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.
“Repels ticks and mosquitoes for up to 10 hours”
DurationModerateWithin the partial-protection window: complete (bite-free) protection is ~7 h, with reduced protection persisting to ~12 h. The claimed 10 h is optimistic but plausible as partial protection.
“Repels ticks that may carry Lyme disease”
EfficacyStrongRegistered label claim; EPA's repellency tool does not list a specific tick protection time for this registration (the company chose not to display one).
“DEET-free formula”
Deet FreeStrongAccurate for a picaridin-based product.
“Picaridin 15%”
EfficacyStrongActive ingredient concentration from EPA registration database.
