Retailer links may earn us a commission. Scores are never affected.
Pros
- Heavy-duty tick and mosquito defense, 8 to 10 hours on mosquitoes and 8 to 10 on ticks from 20% picaridin.
- Fully disclosed, with picaridin's light, gear-safe feel.
Cons
No significant downsides for its role.
The full review
An unscented pump spray bringing 20% picaridin under an EPA registration, this one is recommended for maximum protection. Picaridin's evidence is definitive, the dermal profile reads near spotless, and all 9 audited claims came back strong or moderate. The label's up to 12 hours reflects reduced biting, while our model puts complete protection at a genuinely strong 8 to 10 hours on mosquitoes and the same 8 to 10 on ticks. The one thing keeping it a step behind its Natrapel sibling is transparency, since the inert ingredients are not fully accounted for. A moderate aquatic toxicity ding is the only safety deduction, and picaridin's light, gear-safe feel makes it easy daily wear.

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 ~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.

Claims audit
What the marketing says, versus what the evidence supports.
“Safe for the whole family, including pregnant women and small children, when used as directed”
SafetyModerateBrand FAQ (nonatz.com) explicitly states low absorption, non-irritant, non-skin-sensitizing, and safe for pregnant women and small children; extends the existing 'use with confidence on the whole family' claim.
“Made in the USA”
EfficacyStrongStated on brand page and Amazon/Walmart titles; crafted in Savannah, Georgia.
“Unscented, non-greasy, non-staining, dries quickly”
OtherModerateCosmetic feel claims; brand FAQ also claims wide material/plastics compatibility.
“DEET-free formula”
Deet FreeStrongActive is picaridin; brand FAQ confirms no DEET.
“Use with confidence on the whole family”
Kid SafeModeratePicaridin is considered low-risk by EPA/WHO; label still restricts application to children's hands and requires adult application for children.
“Up to 12 hours of protection against mosquitoes, including those carrying West Nile Virus”
DurationStrongConsistent with our complete-protection estimate (~10 h).
“Repels biting flies, stable flies, black flies, gnats, chiggers, sand flies, and no-see-ums for up to 8 hours”
DurationStrongConsistent with our complete-protection estimate (~10 h).
“Up to 12 hours of protection against ticks”
DurationStrongConsistent with our complete-protection estimate (~10 h).
“Picaridin 20%”
EfficacyStrongActive ingredient concentration from product labeling and EPA registration data for base reg 66243-4.
