Pros
- Strong all-day defense, 8 to 10 hours on mosquitoes and 8 to 10 on ticks from 20% picaridin.
- Light, low-odor, and gear-safe.
Cons
No significant downsides for its role.
The full review
Built on 20% picaridin, this DEET-free spray is the top performer in this group and a recommendation in the maximum protection tier. Picaridin is backed by definitive published evidence, two of three audited claims are strong with the third moderate, and skin safety reads near-perfect with no notable sensitization or irritation. The label touts up to 12 hours, which reflects reduced biting; our own model is more conservative but still generous, estimating roughly 8 to 10 hours of complete mosquito protection and 8 to 10 against ticks (EPA Reg. #93362-1). The lone soft spot is transparency, where the active percentage is fully disclosed but the inert ingredients are not accounted for, with a minor aquatic-toxicity note trimming safety slightly. Light, low-odor, and gear-safe, it is strong all-day defense.

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 ~18 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 ~18 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.
