Pros
- Backcountry-grade 40% DEET, a solid 6 hours that shrugs off sweat, with 5 of 6 claims verified.
- Everything disclosed and EPA-registered.
Cons
- Strong DEET feels oily and can melt plastics and synthetics, so keep it off your gear.
The full review
A high-concentration 40% DEET aerosol that lands a clear recommended for heavy-exposure outings. DEET's definitive evidence and clean skin safety anchor the verdict, and 5 of 6 audited claims hold up. Protection comes straight from the EPA-registered label: 6 hours of complete mosquito protection and 3 to 5 against ticks, a dependable window helped by the sweat-resistant formula. The main deduction is transparency, strong on the active but silent on the full inert list. At this strength DEET can affect plastics and synthetics, so this is a deep-woods tool rather than an everyday spray.

Effectiveness45%94Mosquitoes: 6 h of complete protection. Ticks: 3–5 h of complete protection. Protection times come from the product's EPA-registered label (a manufacturer maximum, capped to a defensible ceiling). 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)
From the product's EPA-registered label (manufacturer maximum against mosquitos, treated as an upper bound). 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 ~9 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
Do not spray in enclosed areas. Hold the container upright 6 to 8 inches from skin or clothing and spray with a slow, sweeping motion, slightly moistening skin; do not use under clothing. Do not spray directly onto face: spray on hands first, then apply sparingly, avoiding eyes and mouth. When using on children, apply to your own hands first; do not apply to children's hands. After returning indoors, wash treated skin with soap and water and wash treated clothing before wearing again; the spray may damage some synthetic fabrics, plastics, and finished surfaces.
