Natural Insect Repellents: 10 to Try and More

If you’ve ever tried to enjoy a backyard hang only to become the main course for a squad of mosquitoes,
you already know this: bugs do not respect vibes. They are tiny, winged opportunists with the confidence
of someone who never pays rent.

So it makes total sense to look for natural insect repellentsespecially if you’re trying to
cut down on harsh scents, avoid greasy textures, or simply prefer plant-based bug spray when it can do the job.
The catch? “Natural” isn’t a magic spell. Some natural options work surprisingly well. Others are basically
expensive perfume with a motivational speech.

This guide breaks down 10 natural repellents worth trying (plus smart add-ons that make any repellent work better),
how long they typically last, and the practical trade-offsbecause the goal isn’t to smell like a spa.
It’s to not get bitten.

What “Natural” Really Means on a Repellent Label

In the U.S., the easiest way to separate “helpful” from “hopeful” is to look at whether a repellent is
EPA-registered. EPA-registered repellents have labeled active ingredients and instructions that
reflect safety and effectiveness when used as directed. Many plant-derived ingredients fall into this category.

Here’s the part that trips people up: essential oils and plant-derived active ingredients are not always the same thing.
For example, products containing oil of lemon eucalyptus (OLE) or PMD can be excellent, but
“pure eucalyptus essential oil” is a different product entirelyand doesn’t have the same evidence or performance.
Translation: a plant name on the label doesn’t guarantee bite-proofing.

The 10 Natural Insect Repellents to Try

Below are the standouts people reach for when searching for a DEET alternative that’s still grounded in real-world use.
For each option, you’ll see what it’s best for, how it’s typically used, and the “gotchas.”

1) Oil of Lemon Eucalyptus (OLE) / PMD

Best for: Mosquito-heavy areas where you want strong protection without classic “bug spray smell.”
Why people like it: It’s plant-derived, widely available, and can offer solid protection time in many products.

• How it works: OLE products rely on PMD (para-menthane-diol) as the key repelling compound.
• What to buy: Look for EPA-registered OLE/PMD products (not “eucalyptus essential oil”).
• Pro tip: Apply evenly; patchy spraying creates “mosquito landing zones.”
• Watch-outs: Can irritate eyes/skin in some people. Not recommended for kids under age 3.

2) 2-Undecanone (a Plant-Derived Ingredient)

Best for: People who want a plant-derived active ingredient with a more “serious” repellent reputation.
Why people like it: It shows up in EPA-registered repellents and is recognized as a plant-derived ingredient option.

• What to expect: Often used for mosquitoes, and sometimes marketed for broader outdoor pest protection.
• How to use: Follow the label exactlyespecially reapplication timing.
• Watch-outs: Like many actives, can bother sensitive skin; do a small test spot first.

3) Catnip Oil (Nepetalactone)

Best for: Short outings, porch hangs, dog walkstimes you want some protection without committing to a full chemical arsenal.
Why people like it: Catnip isn’t just for chaotic cats; its key compounds can repel mosquitoes in testing.

• What to expect: Promising repellency in controlled studies, typically for shorter windows than top-tier repellents.
• Best use: Great for low-to-moderate mosquito pressure or as a backup option.
• Watch-outs: Your neighborhood cats may become emotionally invested in your personal space.

4) Citronella (Oil of Citronella)

Best for: Light mosquito pressure, quick outdoor tasks, and “I’m stepping out for 20 minutes” moments.
Why people like it: It’s iconic, familiar, and available in sprays, lotions, and lots of outdoor products.

• Reality check: Citronella can help, but it generally doesn’t last as long as stronger actives.
• Skin vs. space: Sprays/lotions differ from citronella candlescandles are “area help,” not a personal force field.
• Watch-outs: Can irritate skin. Some citronella products warn against use on very young infants unless directed by a doctor.

5) Soybean Oil–Based Repellents

Best for: People who want a gentler-feeling, lotion-style repellent for everyday outdoor time.
Why people like it: Some soybean oil formulations have shown measurable bite protection (often around the “short to moderate” range).

• What to expect: Better than many DIY essential oil sprays, but typically not an all-evening solution.
• Best use: Yardwork, playground visits, short hikesreapply as needed.
• Watch-outs: If mosquitoes are fierce or disease risk is high, consider stepping up protection.

6) Geraniol (Often from Geranium or Related Plants)

Best for: Outdoor sitting areas, patios, and “keep them away from where we’re hanging out” strategies.
Why people like it: Geraniol is used in some botanical repellent products and has evidence for repelling mosquitoes in certain setups.

• How it’s used: Sometimes as a topical ingredient, often as part of area-based approaches.
• What to expect: Helps most when combined with other bite-reduction habits (fans, covered skin, timing).
• Watch-outs: Like many botanicals, duration can be shorter due to evaporation.

7) Clove Oil (Eugenol-Rich)

Best for: Emergency “I forgot repellent” moments or short-duration useif your skin tolerates it.
Why people like it: Clove is a classic essential oil repellent ingredient and shows repellent potential in studies.

• What to expect: Some repellency, often limited by skin irritation risk and smell intensity.
• Best use: Consider applying to clothing rather than skin if you’re sensitive (and the product label allows it).
• Watch-outs: Clove oil can irritate skinpatch test, avoid eyes, and don’t use it undiluted.

8) Peppermint Oil (Menthol/Menthone Aroma Compounds)

Best for: Mild insect annoyance, short stints outside, and people who love a “fresh” scent.
Why people like it: Peppermint’s strong aroma can deter some insects, and it’s commonly used in natural pest products.

• Reality check: Peppermint is more “deterrent” than “all-night shield.”
• How to use: Choose a properly formulated product; avoid DIY slapping on straight essential oil.
• Watch-outs: Peppermint oil can be irritatingespecially at higher concentrations.

9) Cedarwood Oil

Best for: Clothing/gear adjuncts, and situations where you want to discourage insects from lingering nearby.
Why people like it: Cedar has a long history in pest deterrence (think: cedar closets).

• What to expect: Can contribute to repellency, but may not provide long protection when used alone on skin.
• Best use: Combine with physical barriers (long sleeves/pants) and consider treating gear rather than relying on it as your only defense.
• Watch-outs: Essential oil formulations can be short-lived and may irritate sensitive skin.

10) Lavender Oil (and Lavender-Forward Blends)

Best for: Light bug pressure and people who want a “wearable” scent that’s not full-on bug spray.
Why people like it: Lavender is popular in natural repellent blends and may offer modest deterrence in some conditions.

• Reality check: Many lavender options are best as “supporting actors,” not the lead superhero.
• Best use: Good for quick errands outside, especially when paired with clothing coverage.
• Watch-outs: Lavender oil can still irritate skin; choose a formulated product and patch test.

How to Make Natural Repellents Work Better (Without Becoming a Science Project)

The most underrated truth about mosquito bite prevention: repellent is only one part of the plan. If you want fewer bites,
stack the odds in your favor.

Use the “Layer Cake” Strategy

1. Cover up first: Long sleeves, long pants, socksespecially at dawn and dusk.
2. Add airflow: A simple fan on a patio can make it harder for mosquitoes to land and track you.
3. Then add repellent: Apply to exposed skin and reapply based on the label (or sooner for short-lived botanicals).
4. Reduce breeding sites: Dump standing water (saucers, buckets, toys, clogged gutters). Small water = big mosquito factory.

Repellent Placement Matters

• Don’t miss ankles and lower legs: Mosquitoes love a sneak attack from below.
• Apply after sunscreen: If you use both, put sunscreen on first, let it set, then apply repellent.
• Avoid hands and eyes: Especially for kidshands go everywhere, and eyes are sensitive drama queens.

DIY Natural Repellent: Should You Make Your Own?

DIY repellent is tempting (it’s thrifty! it’s crunchy! it makes your kitchen smell like a wizard’s apothecary!),
but it comes with two big problems: unreliable strength and higher irritation risk.
Essential oils evaporate quickly, and “a few drops” is not a consistent measurement when mosquitoes are treating you like a buffet.

If you still want a DIY approach for low-stakes situations (think: light bugs, short time outdoors), keep it simple:
use a properly formulated product whenever you’re in a high-mosquito area, traveling, or concerned about mosquito-borne disease.
For kids, pregnant people, or anyone with sensitive skin, store-bought EPA-registered options are usually the safer choice.

Natural Repellents vs. High-Risk Situations

If you’re hiking in tick territory, traveling where mosquito-borne illnesses are a concern, or you know your area is having a
“mosquito summer blockbuster season,” the smartest move is to prioritize what works best and is used correctly.
Plant-derived repellents like OLE/PMD can be a strong option, but many essential-oil-only products may not last long enough for real protection.

Bottom line: match the repellent to the risk. It’s okay to go gentler for a backyard dinner.
It’s also okay to bring out the heavy hitters for a swampy trail.
The goal is fewer bitesbecause bites aren’t just annoying; they can be risky.

FAQ: Natural Insect Repellents

Are natural insect repellents safer than conventional ones?

Not automatically. “Natural” ingredients can still irritate skin or trigger allergies. Safety depends on the ingredient,
concentration, and how you use it. EPA-registered repellents (including some plant-derived ones) come with clearer guidance.

Which natural repellent works best for mosquitoes?

Many experts consider oil of lemon eucalyptus (OLE)/PMD one of the strongest plant-derived options when you choose an EPA-registered product.
After that, plant-derived actives like 2-undecanone and certain formulated botanicals may help, though duration varies.

Why do essential oil repellents wear off so fast?

Because they’re volatilemeaning they evaporate quickly. That can make them great for candles and short-term deterrence,
but it often means more frequent reapplication if you’re using them on skin.

Can I use natural repellents on kids?

Some can be used, but age guidance mattersespecially for OLE/PMD and certain botanicals. Always follow the product label,
avoid applying to kids’ hands and faces, and consider physical barriers like netting for babies.

Field Notes: Real-Life Experiences With Natural Insect Repellents (The Honest 500-Word Add-On)

I used to think “natural repellent” was basically a scented wish. Then I moved into a neighborhood where mosquitoes treat
porch lights like a dinner bell. You learn fast. The first thing I noticed is that natural repellents aren’t one category
they’re a whole personality spectrum. Some are like a reliable friend who shows up early with snacks. Others are like a flaky
acquaintance who says “I’ll be there in five” and never arrives.

The biggest lesson: duration is everything. A lot of essential-oil blends feel nice going onlight, not sticky,
and they smell like you’re about to lead a meditation retreat. But 30–60 minutes later, the mosquitoes are back like,
“Namaste, we brought forks.” When I used citronella-based sprays, I loved the smell, but I had to treat it like lip balm:
reapply early, reapply often, and accept that it’s a short-date kind of product.

Oil of lemon eucalyptus (OLE/PMD) was the first plant-based option that actually made me stop checking my arms every two minutes.
The scent is different from straight citronellait’s more “clean outdoors” than “tiki torch,” and it felt closer to conventional
repellent performance. On evenings when I was outside for a couple of hours, it held up noticeably better than most essential-oil-only sprays.
The trade-off is that you still need to apply it carefully (keep it away from eyes), and if you’re sensitive, you learn quickly whether your skin agrees.

Catnip oil products were a surprise. I expected a gimmick. Instead, they worked decently for short burstslike taking the trash out,
walking the dog, or sitting outside long enough to finish a coffee. The catch is that “decently” is not “invincible,” and if you
stay out long past the product’s prime, you pay the price in itchy welts.

My most effective “natural” hack turned out not to be a spray at all: air movement + coverage.
A simple fan on the patio changed everything. Combine that with light long sleeves and socks, and suddenly the repellent
doesn’t have to carry the whole team on its back. I also got religion about dumping standing waterbecause nothing ruins a
“natural living” moment like realizing you’ve been raising mosquitoes in a forgotten plant saucer.

If you want a realistic takeaway: natural repellents can absolutely earn a place in your routine. Just treat them like tools,
not miracles. Pick the right one for the situation, reapply when needed, and stack your defenses. That’s how you go from “bug buffet”
to “pleasant human enjoying the outdoors like it’s your legal right.”
