Pros
- A no-nonsense 25% DEET spray, 5 to 6 hours of reliable cover with the whole formula disclosed.
- Settled science and a clean safety read at this everyday strength.
Cons
- Usual DEET trade-offs: a slightly tacky feel, and keep it off plastics and lenses.
The full review
A straightforward 25% DEET spray that lands solidly in recommended territory. The strength is the active itself: DEET carries definitive evidence and the skin safety reads clean, with all 5 audited claims holding up. We model 5 to 6 hours of complete mosquito protection and 3 to 4 against ticks, a practical all-day window without the plastic-softening tendency of the highest concentrations. The label's up to 8 hours reflects reduced biting rather than bite-free time. The main thing holding it back is transparency, where the full active concentration is disclosed but the inert list is not, and as with all DEET it is not for use on infants.

Effectiveness45%92Mosquitoes: 5–6 h of complete protection. Ticks: 3–4 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 ~11 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 ~7 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
Apply to exposed skin, using just enough repellent to cover exposed skin and/or clothing. Do not spray directly onto the face - spray on hands first and then apply, avoiding eyes and mouth and applying sparingly around ears. Do not apply over cuts, wounds, or irritated skin, do not apply to young children's hands, and do not use on infants. After returning indoors, wash treated skin with soap and water and wash treated clothing before wearing again.
