Retailer links may earn us a commission. Scores are never affected.
Pros
- Top-tier tick and mosquito defense, 8 to 10 hours on mosquitoes and 8 to 10 on ticks from 20% picaridin.
- Picaridin feels light and low-odor, won't melt plastics, and the eco-spray skips aerosol propellant.
Cons
No significant downsides for its role.
The full review
Sold as an alternate of the Natrapel 8 Hour formula, this 20% picaridin Eco-Spray sits firmly in our recommended, maximum-protection tier. The effectiveness pillar is outstanding on modeled complete protection of 8 to 10 hours against mosquitoes and 8 to 10 against ticks, so the label's 'up to 12 hours' reflects repellency rather than bite-free time. Picaridin's published evidence anchors the case, safety reads clean, and all 7 audited claims hold up strong. Transparency is the only thing holding it back, with full active disclosure but limited quantification of the rest of the formula. DEET-free and low-odor, it sprays at any angle, skips aerosol propellant, and stays friendly to clothing and gear.

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.
