Retailer links may earn us a commission. Scores are never affected.
Pros
- One of the stronger botanicals, about 2 hours of real mosquito cover from a soybean-heavy blend.
- Fully disclosed, with a glycerin base that feels gentler than alcohol sprays.
Cons
- Short and mosquito-only, with no proven tick protection.
- Clove and geranium oils add a sensitization risk.
The full review
This FIFRA 25(b) botanical spray lands as recommended with caveats, and what carries it is transparency: every active is quantified and the full formula is accounted for. The soybean-heavy blend delivers roughly 2 hours of complete mosquito protection, which is genuinely useful for a cookout or an evening outside, though ticks go essentially uncovered. The evidence pillar is reasonable, anchored by soybean oil at 72.75% near its studied dose, with a couple of weaker audited claims trimming it slightly. Safety is the softer spot, with high sensitization risk from clove oil at 0.25%, high irritation from thyme at 0.50%, and a pregnancy caution. Honest and gentle in concept, just short-lived and unproven on ticks.

Effectiveness45%50Mosquitoes: 2 h of complete protection. Ticks: minimal or unproven 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 (low confidence)
Estimated complete protection time from active ingredient + concentration; the source research used a lotion-style formulation, matching this spray (no format adjustment). Partial protection (reduced but real bite suppression) is modeled to extend to ~3 h as repellency decays.
Tick estimate basis (low confidence)
Botanical actives show little to no reliable tick protection; reapply very frequently if used at all.

Claims audit
What the marketing says, versus what the evidence supports.
“DEET-free natural essential oil repellent”
Deet FreeStrongPlant-based FIFRA 25(b) essential oil formula containing no DEET; consistent with brand positioning.
“Independently tested, made-in-USA formula”
EfficacyModerateBrand page states the formula was independently tested and proven to repel mosquitoes for up to 5 hours; made in USA.
“Great for the whole family when used as directed”
Kid SafeWeakGeranium oil at 1.00% is a high skin-sensitization/irritation risk at this level, so a "gentle / safe-for-kids" claim overstates the safety profile.
“FIFRA 25(b) minimum-risk product”
OtherStrongConsistent with the label's active/inert declaration and exempt status; exempt from federal EPA registration.
“Repels mosquitoes for up to 5 hours”
DurationWeakOverstates duration: complete (bite-free) protection is ~2 h and reduced/partial protection only to ~3 h; the claimed 5 h is not supported as complete protection.
“Essential oil and soybean oil active blend with a fresh herbal scent”
NaturalStrongFull active/inactive ingredient declaration is disclosed.
How to apply it
Apply to exposed skin, avoiding contact with eyes. Wash hands thoroughly with soap and water after handling and before eating or drinking. Reapply when protection wears off (up to 5 hours) or after swimming, sweating, or toweling off. If skin sensitivity occurs, wash with mild soap and water and discontinue use. Store in a cool, dry place away from children and pets.
