Where most "natural repellent" lists go wrong
They list pleasant-smelling botanical sprays, imply they are equivalent to DEET, and send you into a
mosquito-heavy evening under-protected. You get bitten, and conclude natural options do not work.
So we separate two genuinely different things.
Oil of lemon eucalyptus (OLE) is plant-derived, EPA-registered, and has efficacy data in the same
conversation as lower-concentration DEET. If you want plant-derived protection that holds for hours,
this is it. It is not the only non-DEET option: the CDC also lists picaridin and IR3535 as EPA-registered.
Our picaridin pick, with the picaridin products we read and did not pick, is on DEET-free bug spray, by active ingredient; we have not added an IR3535 product yet.
Citronella-family balms and sprays are pleasant, gentle and short-lived. Good for a short evening
outside, for children too young for OLE, and for people who react to most things. Not an answer for
a long hike under real mosquito pressure.
The one hard rule: OLE is not for children under three. The Repel and Cutter label says so, the
CDC says so, and we hold the same rule for every lemon eucalyptus product here — so for babies and
toddlers, physical protection does the work.
On DEET itself
Worth being fair about, since this is a site for people avoiding it.
DEET is the most studied repellent there is, and regulators consider it safe used as directed. Many
families still prefer to avoid it, and the point of our
cheat sheet is that you no longer trade effectiveness for that
preference — which was not true fifteen years ago.
The part that beats every product on the page
Empty standing water once a week. Plant saucers, buckets, watering cans, gutters, forgotten
toys, birdbaths, the base of a paddling pool. Mosquitoes breed in remarkably little water — a saucer
under a pot plant is a functioning nursery — and removing breeding sites near the house does more
than repelling adults one at a time.
Put a fan on the porch. Mosquitoes are weak fliers and largely give up against moving air.
Both are free, and both outperform anything you can apply.
Two application notes
Apply to your own hands first, then to a child's exposed skin — never onto small hands going straight
to a face.
And buy your sunscreen separately. Combination sunscreen-repellent products need reapplying on two
incompatible schedules, so one of the two always ends up wrong. Our
sunscreen cheat sheet covers that side.
