Retailer links may earn us a commission. Scores are never affected.
Pros
- Built for tick country, 4 to 6 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
This 15% picaridin pump spray is positioned for tick defense and lands a clear recommended. Picaridin brings settled evidence and clean skin safety without DEET's gear-damaging drawbacks, and the label's up to 5 hour figure lines up with our window. The tick framing is well founded: we carry 4 to 6 hours of complete tick protection from the EPA-registered label, alongside 5 hours against mosquitoes, with all 4 audited claims holding up. The score is held back mainly by transparency, where the active is disclosed but the inert list is not. Its light feel makes it easy to wear all day, a sensible pick when ticks are the primary concern.

Effectiveness45%93Mosquitoes: 5 h of complete protection. Ticks: 4–6 h of complete protection. Protection times come from the product's EPA-registered label (a manufacturer maximum, capped to a defensible ceiling). 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)
From the product's EPA-registered label (manufacturer maximum against mosquitos, treated as an upper bound). Partial protection (reduced but real bite suppression) is modeled to extend to ~9 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 ~11 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.

How to apply it
Hold the bottle 4 to 6 inches from skin while spraying, keeping the nozzle pointed away from the face, and slightly moisten skin; excessive amounts or frequent reapplication should be unnecessary. Do not apply more than three times per day, and do not spray in enclosed areas or directly onto the face — spray on hands first, then apply, avoiding eyes. When using on children, apply to your own hands and then to the child, avoiding their hands, mouth, and eyes. After returning indoors, wash treated skin with soap and water and wash treated clothing before wearing again.
