The 10 Best Natural Mosquito Repellents

Mosquitoes are basically tiny flying syringes with a passion for ruining cookouts. And while “natural” repellents
sound like the wholesome, crunchy solution, the truth is a little more complicated: some plant-based options work
surprisingly well, others work… for about as long as it takes to say “Where’s the bug spray?”

This guide cuts through the hype and pulls together what reputable U.S.-based public health agencies, medical
experts, and peer-reviewed research say about natural and plant-derived repellents. You’ll get the best options,
how long they tend to last, and how to use them safelybecause “all-natural” and “rub directly into eyeballs” are
not the same vibe.

Before We Start: What “Natural” Really Means (and Why It Matters)

In mosquito-repellent land, “natural” usually falls into three buckets:

• Plant-derived active ingredients that appear in EPA-registered repellents (strongest evidence).
• Plant oils/essential oils used in commercial blends or DIY dilution (mixed evidence, often shorter-lasting).
• Plant-based “minimum risk” ingredients (may be exempt from full EPA registration in some cases, but still require careful label reading).

One key takeaway from public health guidance: if you want reliable protectionespecially where mosquito-borne
illness is a concernlook for products with EPA-recognized active ingredients and follow the label.
“Natural” is not automatically safer for everyone (essential oils can irritate skin, trigger allergies, or be unsafe
for young kids if misused).

How We Picked These 10

To earn a spot on this list, a “natural” repellent had to check at least one of these boxes:

• Appears as an active ingredient in EPA-registered repellents (or widely recognized by U.S. public health guidance).
• Has peer-reviewed evidence for repelling mosquitoes (not just “my aunt’s neighbor’s camping story”).
• Has a practical, realistic use case (backyard, travel, hiking, kid-friendly routines), with safety considerations.

Heads-up: the “best” option depends on your situation. A gentle plant-based lotion for a backyard picnic is one
thing. A swampy dusk hike during peak mosquito season is another. (That second one is basically a buffet invitation.)

The 10 Best Natural Mosquito Repellents

1) Oil of Lemon Eucalyptus (OLE) / PMD

If you want the most evidence-backed “natural-ish” repellent, this is the headline act. Oil of lemon eucalyptus
(OLE) and its refined component PMD (p-menthane-3,8-diol) are plant-derived and are recognized in
major U.S. public health guidance as effective mosquito repellents.

• Why it works: PMD interferes with mosquitoes’ ability to locate you (your personal CO₂-and-skin-odor “billboard”).
• What to buy: Look for products that list OLE or PMD as the active ingredient (not just “eucalyptus oil”).
• Reality check: “Lemon eucalyptus essential oil” is not the same as OLE/PMD; public health sources warn not to assume they’re interchangeable.
• Safety notes: Generally avoid OLE/PMD on children under 3 (check labels and pediatric guidance). Keep away from eyes and mouth.
• Best for: Travelers, hikers, and anyone who wants real protection without the classic “bug spray cologne.”

2) 2-Undecanone (Methyl Nonyl Ketone)

2-undecanone is a plant-derived ingredient (often discussed as originally found in certain plants like wild tomatoes)
and is included in U.S. public health guidance as an effective repellent option. It’s less famous than OLE/PMD, but it
has a real track recordespecially in commercially formulated products.

• Why it works: It repels mosquitoes through odor-based interference (mosquitoes are picky, just in the worst way).
• What to expect: Often provides hours of protection depending on the formulation; labels vary, so the product directions matter.
• Safety notes: Can have a strong odor and may irritate sensitive skinpatch test if you’re reactive.
• Best for: Outdoor workouts, yard work, and travel when you want something plant-derived but serious.

3) Catnip Oil (Nepeta cataria)

Yes, catnip: the thing that turns some cats into tiny fuzzy philosophers. Catnip oil contains compounds called
nepetalactones that have shown repellency in research, and catnip oil appears as an active ingredient in
EPA-registered repellents.

• Why it works: Nepetalactone compounds can repel mosquitoes in lab studies and show promise as spatial repellents.
• What to expect: Protection time depends heavily on formulation and concentration. Think “promising,” not “invincible.”
• Safety notes: Essential oils can irritate skinuse products made for skin application and follow labels. Keep away from eyes and broken skin.
• Best for: People who want plant-based options and are okay reapplying more often than with top-tier repellents.

4) Oil of Citronella

Citronella is the classic “mosquito repellent smell” most people recognize immediately. It’s derived from certain
grasses and contains components like citronellal, citronellol, and geraniol. It can helpespecially in lighter
mosquito conditionsbut it generally doesn’t last as long as the heavy hitters.

• Why it works: Strong scent masks the human cues mosquitoes use to find you.
• What to expect: Often shorter protection times than OLE/PMD; reapplication is usually needed sooner.
• Safety notes: Can irritate skin if used undiluted. Use skin-safe products and follow the directions.
• Best for: Backyard dinners, short evening walks, or “I just need something for this 20-minute dog stroll.”

5) Geraniol (Often from Lemongrass, Citronella, or Rose Oils)

Geraniol shows up naturally in several plant oils and is commonly used in “natural” repellent productsespecially
spatial repellents (think outdoor areas, patios, and diffusers rather than only skin application).
University-based profiles and reviews discuss its repellent activity, though outcomes vary by delivery method.

• Why it works: Scent-based disruption; mosquitoes do not appreciate your floral-citrus force field.
• What to expect: Best performance often comes from controlled-release formats (diffusers, treated materials) rather than a quick dab-and-go.
• Safety notes: Can irritate skin and eyes; if using on skin, choose products labeled for skin use and do a small patch test.
• Best for: Patios, porches, and outdoor hangouts where you want area coverage without bathing in spray.

6) Soybean Oil–Based Plant Repellent Blends

Here’s the key phrase: soybean oil–based repellent (a formulated product), not “I rubbed cooking oil
on my arms and became a salad.” In a well-known study comparing repellents, a soybean-oil-based product provided
meaningfulbut relatively modestprotection time compared with longer-lasting conventional repellents.

• Why it works: Oils can form a barrier and carry aromatic compounds; certain formulations have measurable protection times.
• What to expect: Think around the “over an hour” range in some research, varying by product and conditions.
• Safety notes: Some people love the lotion feel; others break out. Patch test if you’re prone to irritation.
• Best for: Kids’ sports sidelines, gardening, or casual outdoor time when you can reapply without drama.

7) Neem Oil (Often in a Carrier Oil Blend)

Neem has a long history in pest control, and U.S.-based pesticide information sources describe neem components as
acting as repellents and feeding deterrents for insects. Some studies have evaluated neem oil mixtures for mosquito
bite reduction, with results varying by mosquito species and formulation.

• Why it works: Neem contains multiple biologically active compounds; azadirachtin is often highlighted for insect-disrupting effects.
• What to expect: Mixed results depending on mosquito type and concentration; the smell is… unforgettable (in a “you’ll never forget” way).
• Safety notes: Many neem products are designed for plants, not skin. Only use products clearly labeled for skin application and follow instructions.
• Best for: People who want botanical options and don’t mind a stronger scentand are careful about product labeling.

8) Lavender Oil (Used Correctly, Usually Diluted)

Lavender gets a reputation as the “gentle” essential oil, and some research reviews discuss essential oils (including
lavender) as having repellent potentialespecially when delivered in ways that slow evaporation. That last part is
important: essential oils evaporate quickly, which can mean shorter protection unless the formula is designed to last.

• Why it works: Aromatic compounds may repel or confuse mosquitoes.
• What to expect: Often shorter duration unless formulated for slow release; more of a “supporting actor” than the star.
• Safety notes: Never apply undiluted essential oil to skin. Use a skin-labeled product or a properly diluted blend; avoid eyes and sensitive areas.
• Best for: Light mosquito pressure, bedtime routines (room sprays/diffusers), and people sensitive to stronger repellent smells.

9) Peppermint Oil (Used Correctly, Usually Diluted)

Peppermint smells like “fresh,” but mosquitoes may interpret it as “absolutely not.” Reviews of essential oils describe
peppermint as having repellent potential in certain applications, but it’s also one of the oils most likely to feel
intense on skincooling, tingling, and sometimes irritating.

• Why it works: Menthol-rich aroma can be unpleasant to insects and may disrupt host-finding cues.
• What to expect: Shorter-lasting than OLE/PMD; best for quick outings when you can reapply.
• Safety notes: Peppermint can sting, especially if overused or applied too close to eyes/face. Choose skin-safe products and patch test.
• Best for: Quick evening errands, short walks, and people who like a “minty fresh” approach.

10) Thyme Oil (Evidence-Backed Among Essential Oils, But Handle With Care)

Among essential oils studied for mosquito repellency, thyme oil has shown comparatively strong performance in some
research, with protection times varying by concentration. The catch? More potent oils can also be more irritating,
and DIY “stronger is better” can backfire on your skin fast.

• Why it works: Thyme contains compounds (like thymol and carvacrol) that can repel mosquitoes in controlled tests.
• What to expect: Potentially longer protection than many other botanicals, but still typically not in the “set it and forget it all day” category.
• Safety notes: High irritation potential if misused. Stick to products designed for skin or expert-formulated blends. Patch test is non-negotiable here.
• Best for: Adults looking for a stronger essential-oil option when they can apply carefully and reapply as needed.

How to Use Natural Repellents So They Actually Work

Read labels like your ankles depend on it (because they do)

The biggest performance difference often isn’t “which plant,” it’s the formulation. Oils evaporate.
Lotions stick. Controlled-release systems last longer. If the label says reapply every 2 hours, that’s not a
suggestionit’s a mosquito prevention schedule.

Use the “layering” strategy (the mosquito-proof lasagna method)

• Start with clothing: Long sleeves, light colors, and socks when possible.
• Add airflow: A fan on a patio can dramatically reduce mosquito landings (mosquitoes are not great flyers in wind).
• Then add repellent: Apply to exposed skin only, avoid eyes/mouth, and wash off when you’re done outdoors.
• Remove standing water: Mosquitoes breed in it. A bottle cap of water can be a baby-mosquito spa.

Kids, sensitive skin, and “natural” products

Pediatric guidance commonly warns against using OLE/PMD on children under 3, and essential oils can be irritating
for anyoneespecially kids with eczema or sensitive skin. When in doubt, choose EPA-registered products made for
children and follow pediatric recommendations for application (adults apply to hands first, then gently to the
child’s exposed skin, avoiding hands/face).

Quick FAQ (Because Mosquitoes Don’t Wait for You to Google)

Do citronella candles work?

They can help a little in a small area with low wind, but they’re generally not as reliable as skin-applied repellents.
If you’re getting swarmed, a candle is basically a romantic mood light for mosquitoes.

Can I just mix essential oils into water and spray?

Oil and water don’t mix well without proper formulation, which means you can end up with uneven concentrations
(including a surprise “hot spot” of undiluted oil on your skin). If you want natural, the safest move is to buy a
product formulated for skin and follow the label.

What’s the most “natural” option that’s still strong?

In most U.S. public health guidance, oil of lemon eucalyptus (OLE/PMD) and 2-undecanone stand out as
plant-derived options with real evidenceespecially when used as labeled in commercial products.

Real-World Experiences: What Using Natural Repellents Is Actually Like (About )

In real life, choosing a natural mosquito repellent feels a bit like picking shoes: the best pair depends on where
you’re going and how much suffering you’re willing to tolerate for aesthetics. For example, a light citronella-based
spray can be perfect for a quick backyard watering session. You step outside, do your plant-parent duties, and come
back in before mosquitoes have time to text their friends: “Hey, free snacks on the patio.”

But then there’s the dusk-by-the-water situation. If you’ve ever sat near a lake at sunset, you know mosquitoes
don’t politely wait to see what brand you picked. In heavier mosquito pressure, many people notice a big difference
between “smells natural” and “holds up long enough to finish grilling.” That’s where OLE/PMD products tend to win
fans: they feel closer to conventional repellents in how long they last, without the same scent profile. People often
describe the experience as “I can actually talk to my friends instead of doing the constant ankle-slap dance.”

Another common experience: reapplication reality. A lot of essential-oil-based repellents work decently at
firstthen fade fast, especially if you’re sweating, swimming, or wiping your arms with a towel. Peppermint can feel
refreshing initially (a little spa moment), but it can also feel “too much” if you accidentally apply near your face.
Lavender tends to be more subtle and pleasant, but because it’s usually less aggressive against mosquitoes, people
often treat it as a “nice bonus” for light exposure rather than their only defense in peak season.

Families often develop a system. For kids’ soccer games, a soybean-oil-based lotion can be an easy win: quick to
apply, less drippy, and generally less dramatic than an aerosol cloud drifting across the bleachers. Parents also
notice that “natural” doesn’t guarantee “no reactions,” so patch testing becomes part of the routineespecially for
kids with sensitive skin. If a product stings, reddens, or smells like an herbal science experiment gone wrong, it’s
not worth the battle.

And then there are the “support moves” that make any repellent feel stronger. People who swear they’ve found the
perfect natural solution usually also do a few smart things: they run a fan on the porch, wear long sleeves during
peak biting hours, and dump standing water from planters. The repellent is the final layer, not the whole strategy.
In practice, that’s the difference between “mosquitoes are annoying” and “mosquitoes have declared me their leader.”

The most consistent real-world lesson: don’t chase perfectionchase fit. For quick errands, a pleasant
citronella or lavender blend may be enough. For long outdoor time, OLE/PMD or 2-undecanone in an EPA-recognized
formulation tends to feel like the best balance of plant-derived and actually-effective. And no matter what you pick,
reading the label and reapplying on schedule is the unglamorous secret sauce.

Conclusion

Natural mosquito repellents can absolutely be part of a smart bite-prevention planespecially when you choose options
with real evidence and use them correctly. For the strongest plant-derived protection, oil of lemon eucalyptus
(OLE/PMD) and 2-undecanone stand out. For lighter-duty situations, citronella, geraniol-based products,
and well-formulated botanical blends can helpjust expect more frequent reapplication.

Finally, remember: the best repellent is the one you’ll actually use consistently. Because mosquitoes don’t care about
your intentions. They care about your ankles.
