Retailer links may earn us a commission. Scores are never affected.
Pros
- A dry-feel, unscented 10% DEET spray that goes on light with no greasy residue or odor, all four claims verified.
Cons
- Lower 10% DEET gives 3 to 4 hours, so reapply for a full day outside.
The full review
This Unscented Dry aerosol uses 10% DEET and lands in recommended-with-caveats territory. Safety is excellent and all 4 audited claims hold up, but the lower concentration yields a modest 3 to 4 hours of complete mosquito protection and 2 to 3 against ticks. The evidence read is dialed back to reflect that the dose sits below DEET's most-studied effective range, and transparency is limited by the undisclosed inert list. The appeal here is feel rather than duration: the dry, powder-like finish and lack of fragrance make it pleasant to wear, though you will reapply more often than with a higher-strength spray.

Effectiveness45%83Mosquitoes: 3–4 h of complete protection. Ticks: 2–3 h of complete protection. Protection times are modeled from the actives, concentration, and format (see methodology). 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 ~7 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 ~5 h as repellency decays.

“Repels mosquitoes that may transmit the Zika, West Nile, Dengue and Chikungunya viruses”
EfficacyStrongDEET 10% is EPA-registered (121-65) against mosquitoes that may transmit Zika, West Nile, Dengue and Chikungunya.
“Unscented formula with a dry, non-greasy feel”
OtherStrongThe product is an unscented dry-feel DEET formula, so 'unscented' and 'dry, non-greasy feel' are verifiable formula-consistent facts.

How to apply it
For outdoor use only; do not spray in enclosed areas. Hold the can 6 to 8 inches from skin and clothing while spraying, keeping the sprayer pointed away from the face, and slightly moisten skin; for maximum protection, spread with the hand after application. Do not spray directly onto the face — spray on hands first and apply sparingly, avoiding eyes and mouth. When using on children, apply to your own hands and then put it on the child; do not apply to children's hands. Frequent reapplication or saturation is unnecessary; after returning indoors, wash treated skin with soap and water and wash treated clothing before wearing again.
