Best Natural Bug Repellents for the Garden in 2026
Whether it’s mosquitoes, fleas, or ticks, we all need protection from biting insects. Learn how to make your own natural "bug spray" without toxic chemicals!
Quick Reference
- Best garden plants for natural bug repellent: lemon eucalyptus, lavender, basil, peppermint, thyme, rosemary, and citronella grass. Grow them at the patio edge and harvest leaves to mix into homemade spray.
- Base recipe (10 percent strength): 4 ounces of water, 4 ounces of carrier (witch hazel, vegetable oil, vodka, or rubbing alcohol), and 1 ounce of essential oil. Reapply every 1 to 2 hours.
- Stronger blend (30 percent): drop to 3 to 3.5 ounces water and carrier each, bump essential oil to 3 ounces. Lasts 5 to 6 hours. Patch-test first.
- CDC-recognized oil: lemon eucalyptus oil (oil of lemon eucalyptus, OLE) is the one plant oil the EPA registers as a biopesticide repellent. Not recommended for children under 3 years old.
- Garden focus: this guide is for plants you grow in your yard and harvest into spray, not store-bought DEET. For body-wear repellents and pet-safe options, see our companion pieces on natural bug repellents and herbal insect repellents.
You step out the back door at dusk to water the tomatoes, and within thirty seconds the mosquitoes have found your ankles. Most rural and suburban gardeners reach the same conclusion every June: there has to be a better way than soaking yourself in store-bought spray every time you weed a bed. The best natural bug repellents for the garden start with the plants already on your seed list. Lemon eucalyptus, lavender, basil, peppermint, thyme, rosemary, and citronella grass all push bugs back when you grow them at the edges of patios and beds, and the same leaves crush down into a homemade spray that lasts the afternoon. The Farmers’ Almanac has shared this approach with readers for years, and the recipes below pair the original Almanac base spray with current EPA and CDC guidance for 2026.
Essential Oils That Bugs Hate
If you would rather not use synthetic repellents, your strongest all-natural defense comes from essential oils, with lemon eucalyptus oil at the top of the list. Lemon eucalyptus oil is not a blend of lemon oil and eucalyptus oil. It is a single oil pressed from the lemon eucalyptus plant. Multiple studies, summarized by the U.S. Environmental Protection Agency and recommended by the Centers for Disease Control and Prevention, show it works on par with low-concentration DEET for repelling mosquitoes. The CDC notes that oil of lemon eucalyptus and its refined form, PMD, are not recommended for children under three years old.
Several other garden-grown essential oils repel bugs, though none quite as long-lasting as lemon eucalyptus. Each of these grows happily in most U.S. vegetable beds and herb borders:
- Lavender: mosquitoes, flies, and moths back off. Plant in full sun along a sunny garden border.
- Thyme: creeping thyme between flagstones releases scent when stepped on. Strong on mosquitoes.
- Basil: a pot at the kitchen door does double duty as a cook’s herb and a fly deterrent.
- Bergamot: citrus-forward, balcony-friendly, attracts pollinators while repelling mosquitoes.
- Peppermint: aggressive grower, best in a pot. Discourages ants, aphids, and mosquitoes.
- Tea tree: sourced from Australian Melaleuca. Buy the oil rather than the plant in most U.S. zones.
- Eucalyptus: the broader eucalyptus family also repels mosquitoes, though the standout for skin application is lemon eucalyptus specifically.
Companion-Plant Strategy: Repellents in the Bed, Not Just the Bottle
The advantage of garden-based bug repellent is that the plants do part of the work before you ever pick a leaf. Penn State Extension’s companion-planting guide notes that strongly scented herbs interplanted with vegetables interfere with the way pests locate host plants. The Almanac’s view: place the repellents at the edges where people sit and along the rows that pests find first.
- Patio and porch edge: lavender, citronella grass, and rosemary in pots or a low hedge. The scent rises with the heat of the afternoon.
- Vegetable rows: basil between tomato plants, marigolds at the head of each row, garlic chives at the bed edge. See our full guide on 10 plants that help keep bugs away for spacing notes.
- Mosquito-prone corners: shaded, damp spots get a stand of mosquito-repelling plants such as catmint, bee balm, and lemon balm. Drain the standing water first.
- Pathways and stepping stones: creeping thyme between flagstones releases its repellent scent every time a foot lands on it.
- Pest hotspots: rotate strongly scented herbs through any bed that took aphid or whitefly pressure last year. See how to combat garden pests naturally for the season-long rotation plan.
Honest caveat: a single basil plant near a tomato does not create a force field. The companion-planting effect is real but modest. Layer the plants with the homemade sprays below, and the combination carries the afternoon.
How to Make Homemade Bug Repellent
Every homemade insect repellent spray has three building blocks: water, the essential oil or blend of your choice, and a carrier to dilute the oil. The Almanac rule of thumb is a 10 percent essential oil mixture, with the remaining 90 percent split half and half between water and the carrying agent. That ratio holds for an evening on the patio. Strong garden work or a humid New England summer evening calls for the 30 percent blend further down.
Basic 10 percent recipe
- 4 ounces of water
- 4 ounces of carrier (witch hazel, vegetable oil, vodka, or rubbing alcohol)
- 1 ounce of essential oil (lemon eucalyptus, lavender, or a blend from the list above)
Mix the three ingredients in an 8-ounce glass spray bottle. Shake before each use. Spray onto exposed skin and clothing, avoiding eyes and broken skin. Plan to reapply every 1 to 2 hours, the same way a CDC-rated 10 percent DEET spray is reapplied.
What Is a “Carrier”?
People use all kinds of things as a carrier, including vegetable oil, rubbing alcohol, vodka, vinegar, and witch hazel. The right choice depends on what the spray is for. Rubbing alcohol or vodka evaporates quickly and will not stain clothing the way almond oil can, but it can dry skin on a long garden day. A vegetable-based oil moisturizes and clings to the skin longer in dry heat. Witch hazel splits the difference and is the Almanac’s go-to for a porch-side bottle.
Stronger 30 percent recipe (for long garden days)
The base recipe lasts as long as a store-bought chemical repellent. A 10 percent mixture of either DEET or essential oil needs reapplication every hour or two. Stronger mixtures last longer. A 30 percent essential oil blend typically holds for 5 to 6 hours, which means one or two applications carry you through a day of weeding, mowing, and the first cool of evening.
- 3 ounces of water
- 3 ounces of carrier (witch hazel preferred for skin)
- 3 ounces of essential oil (lemon eucalyptus alone, or 2 ounces lemon eucalyptus plus 1 ounce of a complementary oil)
- Patch-test on the inside of a forearm before broad application. Strong blends can irritate sensitive skin.
Homemade Tick and Insect Repellent
This is the Almanac’s long-running tick and mosquito blend, the one that has run on these pages since the original Make Your Own Natural Bug Repellent post. Mix and apply to exposed skin before heading outdoors:
- 9 drops citronella essential oil
- 6 drops tea tree essential oil
- 6 drops peppermint essential oil
- 1 tablespoon of carrier oil (almond oil or jojoba oil)
NOTE: Essential oils are powerful and should be used with caution, especially with pregnant women and young children. Essential oils should always be diluted as noted above.
Some oils are toxic to cats and dogs, so please do your research and check with your vet.
Regional Garden Bug Pressure for 2026
Bug pressure on a garden tracks temperature, humidity, and standing water more than the calendar. Match your repellent rotation to the regional window where the worst pests show up.
| Region | Worst garden bugs | Peak pressure | Best garden-grown repellents |
|---|---|---|---|
| Northeast and Mid-Atlantic | Mosquitoes, deer ticks, Japanese beetles | June to September | Lemon eucalyptus, lavender, garlic chives, peppermint |
| Upper Midwest | Mosquitoes, gnats, lone star ticks | May to August | Citronella grass, lavender, marigolds, basil |
| Southeast and Gulf | Mosquitoes, fire ants, lone star ticks, flies | April to October | Lemon eucalyptus, rosemary, lemongrass, mint |
| South Central | Mosquitoes, fire ants, chiggers | April to September | Lemon eucalyptus, basil, rosemary, citronella |
| Mountain West | Mosquitoes, biting midges (no-see-ums) | June to August | Lavender, peppermint, sage, thyme |
| Pacific Coast | Mosquitoes, aphids, whiteflies, leafhoppers | May to September | Basil, lavender, rosemary, garlic chives |
| Canadian Prairies and Maritimes | Mosquitoes, black flies, deer flies | Late May to early August | Lemon eucalyptus, lavender, peppermint, catmint |
The CDC’s mosquito prevention page reinforces a point every gardener already knows: drain standing water around the property first. A bowl, a clogged gutter, or an upturned wheelbarrow rim is enough to hatch a generation in 8 to 10 days.
Garden Bug Prevention Layers
Bug repellents work best as one layer of a three-layer plan. The Almanac approach for the 2026 growing season:
- Reshape the yard. Drain standing water, mow tight along bed edges, trim shrubs where mosquitoes rest in the afternoon, and clear leaf litter under porches.
- Plant the perimeter. Lavender, citronella grass, basil, peppermint, and lemon eucalyptus around patios and along bed edges. Marigolds at the head of every vegetable row. Garlic chives anywhere ants run.
- Spray the gardener. Apply the 10 percent base recipe before a 1 to 2 hour weeding session, the 30 percent recipe for a full day in the heat. Patch-test before you cover both arms.
Reader-agency line: pick the two layers that fit your yard first. The third can wait a season.
Folklore and Old-Time Garden Bug Deterrents
The Almanac has tracked garden bug remedies since 1818, and a handful of old-time methods still earn their keep alongside the modern recipes above.
- New England: a sprig of pennyroyal in a hat brim or pocket. Modern note: pennyroyal essential oil is toxic to pets and pregnant women, so use the dried sprig rather than the oil.
- Appalachian: garlic chives at every garden gate. Anecdotally shifts mosquito interest, measurably deters cabbage worms and ants regardless.
- Southern: rosemary tossed on the coals at an outdoor cookout. The scent doubles the patio’s repellent reach for the length of the gathering.
- Midwestern: a bowl of dried lavender on the porch table. Replace every two weeks for fresh scent.
Folklore that lines up with modern entomology earns a place in the toolkit. Folklore that does not, like rubbing kerosene on a mosquito bite, gets a respectful nod and a firm pass.
Safety Notes for Natural Bug Repellents
- Children under three: oil of lemon eucalyptus and PMD are not recommended. Stick to lighter blends or physical barriers (long sleeves, mosquito netting on strollers).
- Pregnancy: ask your physician before applying any essential oil to skin. Some, including pennyroyal and clary sage, are uterine stimulants.
- Dogs: diluted neem and cedar are tolerated, lavender and peppermint at low concentrations are generally safe. Tea tree, citrus, and pennyroyal are not.
- Cats: essential oils are not recommended for cats. Cats lack key liver enzymes for processing many essential oil compounds. Ask your veterinarian about cat-safe options.
- Sensitive skin: patch-test on the inside of the forearm 24 hours before broad use. Dilute further with carrier oil if any redness shows.
Try a couple of these oils and recipes in your own garden, and you may never need to keep a chemical pesticide on the shelf again.

FAQ: Natural Bug Repellents for the Garden
What is the best natural bug repellent for the garden?
The strongest single-ingredient option is lemon eucalyptus oil (oil of lemon eucalyptus, OLE). The EPA registers it as a biopesticide repellent and the CDC recommends it on par with low-concentration DEET. For a homegrown blend, the 10 percent Almanac base recipe (4 ounces water, 4 ounces witch hazel, 1 ounce lemon eucalyptus oil) lasts 1 to 2 hours per application. For longer coverage, mix the 30 percent recipe.
Which plants should I grow in my garden as natural bug repellents?
For most U.S. and Canadian gardens, the top seven are lemon eucalyptus, lavender, basil, peppermint, thyme, rosemary, and citronella grass. Pair them with marigolds at the head of each vegetable row and garlic chives along bed edges. For a deeper plant-by-plant guide, see the Farmers’ Almanac piece on what to plant to keep bugs away and the regional table in the section above.
Do garden-grown natural bug repellents actually work, or is this folklore?
Both. Lemon eucalyptus oil, citronella oil, and lavender oil have peer-reviewed evidence for repellency at the right concentrations, summarized by the EPA. The companion-planting effect (basil next to tomatoes, marigolds at row heads) is real but modest. The honest Almanac view: keep the recipes that line up with modern entomology, layer the plants for support, and treat single-plant claims as helpful add-ons rather than stand-alone defenses.
How long does homemade natural bug repellent last on skin?
A 10 percent essential oil blend lasts 1 to 2 hours, the same window as a 10 percent DEET spray. A 30 percent essential oil blend lasts 5 to 6 hours. Reapply after swimming, heavy sweating, or rubbing on long sleeves. Store the bottle out of direct sun. Most homemade sprays stay potent for 4 to 6 weeks before the scent starts to fade.
Are natural bug repellents safe for children and pets?
The CDC recommends against oil of lemon eucalyptus and PMD for children under 3 years old. Most other essential oils should be used with caution on young children and during pregnancy. Dilute further with carrier oil and patch-test first. Diluted lavender and peppermint are generally safe for dogs at low concentrations, but tea tree, citrus, and pennyroyal are not. Essential oils are not recommended for cats. Ask your veterinarian about cat-safe flea and tick control.
What is the difference between a garden bug repellent and a body spray?
A garden bug repellent uses the plants you grow at the patio edge and in vegetable rows to drop overall bug pressure, then turns the same harvested oils into a homemade spray for skin and clothing. A body-spray-only approach skips the plants and starts with a store-bought bottle of DEET, picaridin, or oil of lemon eucalyptus. The garden-first path is cheaper, slower to set up, and gives you ingredients you have grown yourself. For body-spray comparisons and pet-safe options, see our companion pieces on natural bug repellents and herbal insect repellents.
What if I am allergic to one of the essential oils?
Patch-test every new oil on the inside of the forearm 24 hours before broad use. If you see redness, itching, or swelling, dilute further with carrier oil and try a different oil from the list above. Lavender and peppermint are the most commonly tolerated. Tea tree and citrus oils trigger more reactions. If an allergic response includes shortness of breath or facial swelling, stop use and call your doctor.

I have citronella plants on my deck..hope they work..
I need a good repellent to help get rid of gnats! It seems everytime I buy dirt for potting some how they eventually get gnats in the plants. HELP! What would you suggest.
Hi Christina, it sounds like you have an encounter with the “fungus gnat,” an all-inclusive name for a huge number of small flying creatures that breed in houseplant soil, and in your case, potting soil. Take a look at the suggestions offered in this article, which we think you’ll find helpful: https://www.gardensalive.com/product/fungus-gnats-tiny-flying-houseplant-pests
I bought fungas knat spray. I had to use on all of my potted indoor plant soil. Not natural spray and i did not use on edible plants.
Try Diatomaceous Earth. Read up on it. Get at Agway or whatever is near you.
How can I keep bees away from my hummingbird feeder. They drive the hummers away.
Bees are terrible creatures of habit: they’d rather return to the same watering hole every day. Simply moving the feeder will help. Honestly though, depending on your climate, the bees are primarily looking for water. Maybe you can add a bee waterer as well.
Need help against Japanese Beetles. Tried Milky Spore to no avail and picking them off which requires 18 hours each day and herbs and flowers. any other ideas?
I bought bags that have an attractive scent from HOME DEPOT only put one in front yard by blackberries and it seemed to get rid of the beetles, I was amazed. my property is 1.35 acre.
I had almost none in back yard.
try neem oil
Need help against Japanese Beetles that are destroying my grapes, roses and plum tree.
I just researched pennyroyal oil and it has been found to be highly toxic both internally and externally. I would be extremely cautious about using the oil for anything!
Wanted to share a mixture I learned on Pinterest. Take plain tap water with 3 garlic cloves. Boil for approx. 15 minutes, then let sit overnight. Next day, pour into a spray bottle. Spray directly on plants.
I’ve used this on my Basil, Mint & other plants that seems to get eaten by little critters in the night. It works Fantastic!!! Spray every other day or so… ?
Thank you! I will try this. Those dang beetles destroyed my grape vine last year just as it started producing good. I have tried everything but this. Thank you
Can you use these products on Dogs?? My dog is a Black Lab mix. The ticks LoVe his fluffy chest. Found 3 on him in 2 days!!!… PLEASE HELP!!!
I’ve been adding small amounts of garlic into my dogs homemade food and its going on 6 weeks not one tick he is Maltese and I was pulling 1-3 off him a day. I give it for one week then off for 4 days you have to research some dogs garlic can be very bad for. Good luck!!
Hi Maureen, good info, thank you!
Most essential oil companies recommend using extreme caution applying oils on animals, children, and pregnant women.
For bed bugs call the folks at Cedar oil store dot com in Texas. They have a very effective product for bed bugs, spiders, etc.
For moths, try fresh or dried bay leaves. Grow your own tree as a houseplant and have fresh leaves or buy from the store spice rack.
For chigger, mosquito and tick repellent I use Pennyroyal oil from hopewell essential oils dot com in Texas for me (often) and our cat (just a little, not too often). They have a number of oils we use a lot, depending on situation. When our cat got very sick, we used “Bacteria Top Gun” and she recovered from being very weak, not eating and just lying around. It saved her life. Just a little on my fingers, spread on her ear tips and back paw pads, night and morning and she was much better. Only did it a few days. She does not like the smell of either oil, so my husband holds her while I rub either of them on.
I have read that studies indicate that the leaves of the beauty bush, Callicarpa, are very effective against chiggers, ticks, mosquitoes, etc. I haven’t tried it yet, but when I find some time, intend to make an herbal oil using olive oil poured over some dried leaves from the bush in our yard and heating just on WARM for several hours in a crock pot. More info online about the process.
