Pros
- A pleasant, citronella-forward spray that's mild and fully discloses its actives.
Cons
- Barely repels, around 12 minutes before bites.
- Citronella adds a sensitization risk, and there's no tick protection.
The full review
The original citronella formula is a situational pick at best, even though it is EPA-registered. The decisive weakness is effectiveness: complete protection models at roughly 0.2 hours, around 12 minutes before bites start, so the pillar nearly bottoms out and there is no demonstrated tick protection. Our audit also flags an overpromise, since the label's roughly 2.5-hour reapply interval is far longer than the product actually protects. Transparency is a genuine bright spot with the full formula disclosed, and safety reflects moderate sensitization and irritation risk from citronella at 5% plus a pregnancy caution. EPA registration and full disclosure are real positives, but they cannot offset a repellent that keeps bugs off for only minutes.

Effectiveness45%14Mosquitoes: 0.2 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.

Evidence & honest claims25%60Citronella oil is well-supported by published evidence, weighted by how close its concentration is to the studied effective dose (base 65). Of 6 marketing claims audited: 3 strong, 1 moderate, 2 weak, 0 unsupported (-1). Labels a reapplication interval (~every 2.5 h) longer than its measured protection — an overpromise (−4).

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 lotion-style formulation, matching this spray (no format adjustment). Partial protection (reduced but real bite suppression) is modeled to extend to ~0.3 h as repellency decays. No published tick complete-protection-time data for citronella — Fradin 2002 measured mosquitoes only.
Tick estimate basis (low confidence)
Botanical actives show little to no reliable tick protection; reapply very frequently if used at all. No published tick complete-protection-time data for citronella — Fradin 2002 measured mosquitoes only.

“Safe for small children and up”

“Plant-based formula carried in purified water, grain alcohol and castor oil with essential oils of cedarwood, peppermint, lemongrass and eucalyptus”

“Effective against mosquitoes, gnats, blackflies and no-see-ums”
EfficacyWeakCitronella at 5% gives only ~0.2 h (~12 min) complete mosquito protection, so broad effective-against-mosquitoes/gnats/blackflies claims overreach.
“Citronella Oil 5%”
EfficacyStrongActive ingredient concentration confirmed in the EPA registration database.
“Up to 2.5 hours of protection against mosquitoes”
DurationWeakOverstates duration: complete (bite-free) protection is ~0.2 h and reduced/partial protection only to ~0.3 h; the claimed 2.5 h is not supported as complete protection.
How to apply it
Apply to exposed skin per the product label directions, avoiding eyes and mouth. Reapply approximately every 2.5 hours for mosquitoes, or sooner after swimming, sweating, or toweling off. Do not allow children to handle the product; when using on children, apply to your own hands first and then apply to the child.
