Pros
- Excellent all-day defense, 8 to 10 hours on mosquitoes and 7 to 8 on ticks from 20% picaridin.
- Picaridin's light feel plus scent options, and it won't harm gear or plastics.
Cons
No significant downsides for its role.
The full review
At 20% picaridin this quick-dry pump spray earns a top-tier recommended in the maximum protection category, with effectively nothing dragging it down. The effectiveness is excellent for a DEET-free formula, with modeled complete protection of 8 to 10 hours against mosquitoes and a genuine 7 to 8 against ticks, all without harming clothing or gear. The evidence behind picaridin is about as definitive as repellent science gets, 5 of 6 audited claims rate strong, and the skin safety reads clean. The full formula including inerts is accounted for, so transparency is strong too. The label's up-to-12-hours figure measures reduced biting rather than bite-free time, so our shorter estimate is expected, not a contradiction.

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 ~14 h as repellency decays.

Claims audit
What the marketing says, versus what the evidence supports.
“Contains no DEET”
Deet FreeStrongWell supported by published evidence
“Non-greasy, quick-dry formula won't damage clothing or gear”
OtherModerateConsistent with picaridin's known material compatibility (unlike DEET, it does not damage plastics/synthetics).
“8-hour protection from gnats, flies, fleas, chiggers, and no-see-ums”
DurationStrongFrom the EPA-accepted label ('Repels biting flies, stable flies, black flies, gnats, chiggers, sand flies, and Scottish biting midges for up to 8 hours').
“Protection from mosquitoes that may transmit West Nile, Chikungunya, Dengue, and Zika, and ticks carrying Lyme disease”
EfficacyStrongPicaridin at 20% gives ~8–10 h complete mosquito and ~7–8 h complete tick protection, supporting the vector list.
“Picaridin 20%”
EfficacyStrongActive ingredient concentration confirmed on the EPA master label.
“12-hour protection from ticks and mosquitoes”
DurationStrongEPA label-approved protection time, confirmed in the EPA repellent search tool (12/12 hours).
How to apply it
Apply evenly to all exposed skin. Do not spray directly onto the face — spray onto hands first, then apply to the face, avoiding eyes and mouth. Do not allow children to handle the product; when using on children, apply to your own hands and then put it on the child. Reapply after about 12 hours (8 hours for biting flies and gnats) or after swimming, sweating, or toweling off, and wash treated skin with soap and water after returning indoors.
