Best Natural Fly Repellent For Outdoors for Patios, Yards, and More

#1 · Best Overall

1. NatureStop Fly Repellent

• Volume: 16 fluid oz
• Form: Aerosol
• Size: 16 oz (Pack of 1)

Best for: Family outdoor fly deterrence.

Why it ranks #1: Designed to discourage flies around patios, gardens, and outdoor living areas, with a 16-ounce spray format suited to targeted outdoor application.

A plant-based formula explicitly aimed at discouraging flies around outdoor living spaces makes NatureStop a focused choice for patios, gardens, and decks. Its 16-ounce aerosol format suits targeted applications around outdoor seating and dining areas, with use around pets and families specified when used as directed.

NatureStop identifies patios, outdoor seating, gardens, and other gathering spaces as application targets, giving buyers a practical starting point for treating the places where they spend time. The 16-fluid-ounce aerosol is a single-container format for those areas, while the plant-based active ingredients align with its positioning as an alternative to harsh chemical-heavy treatments. The product states it is safe around pets and families when used as directed. Its stated goal is to help discourage flies, not to claim a broad multi-pest treatment.

Skip it if you need listed control for mosquitoes, ticks, fleas, and ants across a yard; Wondercide Outdoor Pest Control Spray names those pests.

NatureStop suits households looking for a plant-based fly deterrent for outdoor gathering spots, with directions followed around pets and family. Choose another format if broad yard-pest coverage or a larger supply is central to your routine.

#2 · Best Patio Spray

2. Scram Outdoor Bug Spray

• Volume: 8 fluid oz
• Form: Aerosol
• Size: 8 Fl Oz (Pack of 2)

Best for: Outdoor dining fly spray.

Why it ranks #2: Specifically targets flies around outdoor dining areas, patios, porches, and decks; the pack includes two 8-ounce bottles and four listed essential oils.

Four named essential oils distinguish Scram: lemongrass, peppermint, geraniol, and cedarwood form a plant-based spray aimed specifically at flies around outdoor dining and living areas. Apply it when the wind is calm, let it settle, and then use the patio, porch, or deck.

The directions connect calm-weather application with letting the spray settle before sitting down, making timing part of the outdoor dining routine. Its four active oils—0.80% lemongrass, 0.75% peppermint, 0.30% geraniol, and 0.30% cedarwood—are paired with water, polyglycerol oleate, and glycerin. The pack contains two 8-fluid-ounce sprays, providing separate containers for different areas or occasions. It is plant-based and DEET-free, with flies as its stated outdoor focus.

Skip it if you need a broad yard spray for several kinds of pests; Wondercide Outdoor Pest Control Spray lists mosquitoes, ants, ticks, and fleas.

Scram fits households preparing patios, porches, or decks for outdoor meals and willing to apply ahead of sitting down. Its stated focus is outdoor flies, and the directions make calm conditions and settling time important.

#3 · Highest Capacity

3. Bug Soother Natural Repellent

• Volume: 1 gallons
• Form: Aerosol
• Size: 128 Fl Oz (Pack of 1)

Best for: Farm and livestock areas.

Why it ranks #3: Its one-gallon format suits larger outdoor settings, and the listed target insects include flies, gnats, black flies, and no-see-ums.

A one-gallon, DEET-free formula listed for people and livestock sets Bug Soother apart for farms, barns, and other large outdoor environments. Its plant-derived active ingredient is lemongrass oil, and the stated pest list includes flies, gnats, no-see-ums, mosquitoes, black flies, and sand fleas.

The gallon format offers a substantial supply for outdoor workspaces, pastures, stables, and ranches, while the listed use around adults, children, horses, chickens, livestock, and pets supports a range of farm settings when used as directed. Lemongrass oil makes up 0.8% of the active ingredients; the rest includes water, vanillin, glycerin, castor oil, lecithin, and vitamin E. Its broad listed pest range suits varied outdoor exposure, though the 8.4-pound container is less portable than a small bottle.

Skip it if you want a small liquid bottle for personal carry; Buggins Natural Insect Repellent is a 4-ounce DEET-free liquid.

Bug Soother suits farm and ranch users who need a large supply for people, animals, and outdoor work areas. Its gallon container fits stored use better than carrying between locations, so account for the weight when applying.

#4 · Best Stick Format

4. Mintronella Incense Sticks

• Form: Stick
• Size: 100 Pack

Best for: Patio incense and camping.

Why it ranks #4: Made for outdoor settings including patios, camping, and backyard events; each incense stick burns for about 40 minutes on average.

About 40 minutes of average burn time per stick gives Mintronella incense a defined outdoor-use window for patio meals or camping breaks. The 100-pack combines citronella and peppermint with lemongrass and vanilla fragrance oils, offering a scented, stick-based alternative to applying liquid repellent.

Each bamboo-and-resin stick burns for about 40 minutes on average, so buyers can plan a session around a meal or time outdoors rather than applying a spray. The 100-stick quantity supports multiple outings, and the stay-fresh scent-lock pouch provides storage between uses. Its citronella, peppermint, lemongrass, and vanilla fragrance oils create the stated outdoor scent profile. The product is listed as DEET-free and pet friendly; use remains dependent on lighting and burning incense outdoors.

Skip it if you prefer a ready-to-spray liquid for patio treatment; LEMONGRASS FARMS Scram Outdoor Bug Spray is applied around outdoor dining areas.

This suits campers and patio users who want a scented incense format and can manage a burning stick during an outdoor session. Its roughly 40-minute burn window and reliance on incense make it a different fit from spray-on treatments.

#5

5. Wondercide Outdoor Pest Spray

• Volume: 32 fluid oz
• Form: Aerosol
• Size: 32 Fl Oz (Pack of 1)

Best for: Broad yard pest treatment.

Why it ranks #5: A 32-ounce yard spray with cedarwood oil as its active ingredient; its listed pest targets include common yard bugs, though flies are not singled out.

Coverage of up to 5,000 square feet per ready-to-use sprayer gives Wondercide a clear role in treating larger outdoor areas. Its cedarwood-oil formula is listed for mosquitoes, ants, ticks, fleas, and other common yard bugs, making it a broader yard-control option than a fly-only spray.

The ready-to-use 32-ounce spray avoids mixing, while stated coverage of up to 5,000 square feet helps buyers estimate whether one container suits the yard. Cedarwood oil is the listed active ingredient at 12.63%, accompanied by sesame oil and other ingredients. The product is positioned as a spray-and-play alternative to conventional yard treatments, and directions say to apply as needed until control or desired results are achieved. That repeat-as-needed guidance affects planning for ongoing yard use.

Skip it if you want a spray focused on outdoor dining flies in a two-bottle pack; LEMONGRASS FARMS Scram is sold as two 8-ounce sprays.

This is a fit for yard owners seeking ready-to-use coverage across a broader pest list, rather than only flies. Consider the stated 5,000-square-foot coverage and as-needed application when planning treatment for the whole yard.

#6 · Best Contact Spray

6. Wondercide Mosquito and Fly Spray

• Form: Spray

Best for: Fast contact knockdown.

Why it ranks #6: Specifically lists house flies and several other flying insects among those it kills by contact, and is described for indoor and outdoor areas.

Quick-kill contact action against more than 20 flying bugs is the defining feature of this Wondercide aerosol. It covers mosquitoes, house flies, gnats, and other listed flying pests in indoor and outdoor areas, including kitchens, patios, decks, and yards, for buyers prioritizing direct treatment.

The aerosol is intended to kill by contact, which makes it suited to treating flying bugs encountered in a specific area rather than planning a broad residual yard routine. Its listed active ingredients are 1.47% geraniol and 0.10% lemongrass oil, with white mineral oil, isopropyl myristate, ethyl lactate, and carbon dioxide among other ingredients. The indoor-and-outdoor use range includes kitchens, dining rooms, porches, and yards. Shake before use and follow the label directions.

Skip it if you want a plant-based spray specifically for outdoor dining flies; LEMONGRASS FARMS Scram gives calm-weather patio application directions.

Choose this aerosol for buyers who want direct contact treatment across indoor and outdoor locations and a wide list of flying bugs. Its stated use is different from a spray intended to prepare a patio area before dining.

#7

7. Buggins Natural Repellent

• Volume: 4 fluid oz
• Form: Liquid
• Size: 4 Fl Oz (Pack of 1)

Best for: Compact DEET-free personal use.

Why it ranks #7: A 4-ounce DEET-free liquid lists gnats and flies among its targets, with plant-based active ingredients including geraniol, peppermint, lemongrass, and clove.

A compact 4-ounce bottle and four named plant-based actives give Buggins a straightforward role for buyers seeking a smaller DEET-free repellent. Geraniol, peppermint, lemongrass, and clove are listed as active ingredients, while the title identifies a vanilla mint and rose scent.

The 4-fluid-ounce liquid format is easier to carry or store than gallon-size outdoor sprays, making it a practical scale for personal or occasional use. Its active ingredients—geraniol, peppermint, lemongrass, and clove—are identified as plant-based, and the product is explicitly DEET-free. The title names gnats and flies as targets, connecting the formula to common outdoor nuisances. The supplied details do not specify application directions or coverage, so buyers should not infer a treatment area from bottle size alone.

Skip it if you need a gallon for farms, livestock, or outdoor workspaces; Bug Soother Natural Insect Repellent is listed in a one-gallon size.

Buggins fits buyers who want a small DEET-free liquid with named plant-based actives for gnats and flies. Its 4-ounce size is a boundary for extended or large-area outdoor treatment, where a larger supply makes more sense.

#8

8. Farnam Nature’s Defense

• Volume: 32 fluid oz
• Form: Liquid
• Size: 32 Fl Oz (Pack of 1)

Best for: Horse fly spray concentrate.

Why it ranks #8: Its botanical formula lists several fly types, including stable and horse flies, but it is specifically presented as a spray for horses.

A one-part-concentrate to four-parts-water dilution makes Farnam Nature’s Defense a horse-focused fly spray with a defined preparation step. Its botanical blend includes citronella and other essential oils, and its listed targets range from stable and house flies to mosquitoes and gnats.

The concentrate requires mixing four parts water with one part product, so users must prepare a diluted solution before application and shake both the concentrate and diluted mixture as directed. The 32-ounce product is described as a botanical spray for horses, with a fresh herbal fragrance and a water-based formula. Its target list includes horn, stable, house, horse, and deer flies, along with mosquitoes and gnats. Those horse-specific claims make it a different fit from general patio sprays.

Skip it if you need a ready-to-use spray for patios without mixing; Wondercide Outdoor Pest Control Spray is a ready-to-use yard treatment.

Choose Farnam for horse owners prepared to dilute and shake a botanical fly spray before use. Its listed targets and use are horse-focused, so it is not the simplest match for someone seeking a no-mix patio treatment.

#9

9. Mighty Mint Peppermint Spray

• Volume: 128 fluid oz
• Form: Oil
• Size: 128 Fl Oz (Pack of 1)

Best for: Bulk patio and yard coverage.

Why it ranks #9: The one-gallon natural peppermint-oil spray offers high volume, but the supplied details describe general insect repellent rather than a fly-specific outdoor use.

A full gallon of peppermint-oil repellent gives this Mighty Mint spray a clear role: stocking up for repeated treatment around outdoor areas. Its ready-to-use, high-strength spray format avoids a dilution step, while the oil-based formula suits buyers who want a larger supply on hand.

The 128-fluid-ounce volume can support repeated applications around patios or other outdoor spaces, and the ready-to-use directions keep preparation simple: attach the nozzle to the gallon and spray. Peppermint oil is listed alongside water, glycerin, polyglycerol oleate, and soap, so the formula is not peppermint oil alone. The substantial container weighs 9 pounds, which matters when moving it between storage and application spots. Keep it out of reach of children and pets, as directed.

Skip it if you need a stick format for camping; Farm Raised Candles Mintronella 100 offers portable incense sticks with about 40 minutes of burn time each.

Choose this gallon for outdoor users who want a ready-to-use peppermint-oil spray in a large supply. Its 9-pound container and nozzle attachment suit a storage-and-refill routine better than carrying a compact bottle.

#10

10. Kate’s Peppermint Oil Spray

• Volume: 16 fluid oz
• Form: Oil
• Size: 16 Fl Oz (Pack of 1)

Best for: Multi-pest home and yard use.

Why it ranks #10: This 16-ounce peppermint-and-cedarwood oil spray lists flies among its targets, but its broad indoor and household focus is less tailored to outdoor fly control.

The combination of peppermint and cedarwood oils gives Kate’s spray a broader stated pest list than a peppermint-only formula. Its 16-ounce oil format is positioned for indoor and outdoor areas, from household spaces to the yard, and includes flies among the pests it is intended to repel.

Kate’s identifies peppermint oil and cedarwood oil as its paired plant-based ingredients, with claims covering flies as well as spiders, ants, stink bugs, earwigs, cats, and rodents. That breadth can suit buyers seeking one household spray for varied locations, including basements, attics, and yards. The 16-fluid-ounce bottle is smaller than gallon formats, so it is easier to keep as a household supply but offers less volume for repeated broad-area application. Shake well before use and store cool and dry.

Skip it if you need a gallon for large agricultural spaces; Bug Soother Natural Insect Repellent comes in a one-gallon format for farms and livestock areas.

Pick Kate’s for buyers who want a household-oriented peppermint-and-cedarwood spray that also lists flies among its targets. The 16-ounce volume is a practical boundary for extensive yard treatment or frequent large-area use.
