Best Repellent For Deer Flies: Patches and Sprays Compared

#1 · Best Overall

1. Cutter Backwoods High DEET

• Size: 11 Fl Oz (Pack of 1)
• Form: Aerosol
• Volume: 11 fluid oz

Best for: Explicit deerfly coverage for long outings.

Why it ranks #1: Its listed targets explicitly include deer flies, and the 40% DEET, sweat-resistant formula offers up to 10 hours of protection.

Cutter Backwoods High DEET explicitly names deer flies among the insects its 40% DEET formula repels, directly matching this roundup’s target. The 11-ounce aerosol is also described as sweat resistant and suitable for prolonged outdoor activities, making it a substantial spray option for extended time outside.

The product’s explicit deerfly claim distinguishes it from broader listings that only say biting flies. Its 40% DEET formula is paired with sweat resistance, supporting use during active outdoor time, while the additional facts state protection for up to 10 hours against mosquitoes, ticks, biting flies, gnats, no-see-ums, chiggers, and fleas. The 11-ounce aerosol provides a larger single-can format, though the supplied facts do not give a separate deerfly-specific duration.

Skip it if you prefer a cap-mounted trap instead of aerosol; TredNot Deerfly Patches target deerflies without applying spray to skin.

This is a direct match for buyers wanting an aerosol that explicitly lists deer flies, especially for prolonged outdoor activities. Consider the 11-ounce can format and note that the stated duration is not deerfly-specific.

#2 · Best Chemical-Free

2. TredNot Deerfly Patches

• Size: 12 Count (Pack of 1)
• Form: Patch

Best for: All-day patch for cap wearers.

Why it ranks #2: These odorless, chemical-free 2-by-6-inch patches attach to a hat, trap deerflies, and are listed to last all day.

One patch is listed to last all day, giving TredNot’s 2-by-6-inch adhesive deerfly trap an appealing set-and-wear routine for a day outdoors. The 12-pack is non-chemical and odorless, and attaches to a cap or hat to trap biting deerflies around the head.

The adhesive patch goes on the back of a hat or cap, where the description says deerflies buzzing around the head land and become trapped. A stated all-day lifespan can reduce the need to replace it during a single outing, while the 12-count pack supplies patches for additional days. The product is odorless and contains no chemicals. Its safety information cautions against use with long, blowing hair, which should be tied or tucked under a cap.

Skip it if you have long, loose hair that cannot be tucked under a cap; OFF! Clean Feel provides spray-on coverage for biting flies.

Choose this pack if you wear a cap and want an odorless, chemical-free deerfly trap for a full day. The listed hair caution matters: long hair should be tied up or tucked under the cap.

#3 · Best Patch Multipack

3. TredNot Deerfly Patch

• Size: 12 Count (Pack of 1)
• Form: Patch

Best for: Odorless hat-mounted deerfly trap.

Why it ranks #3: The 12-count provides targeted, non-chemical deerfly trapping on a cap; its description says the adhesive patch is odorless.

A disposable adhesive patch placed on the back of a hat or cap targets deerflies around your head without chemical repellent or odor. This 12-count TredNot pack suits wearers who want a deerfly-specific approach and prefer a trap attached to headwear over spray applied to skin.

Each 2-by-6-inch patch adheres to the back of a hat or cap and traps deerflies as they buzz around the head, putting the product’s action at the area the description identifies. The patches are described as non-chemical and odorless, which makes them a distinct alternative to sprays. With 12 disposable patches in the pack, buyers have multiple replacements for separate outings; application depends on wearing suitable headwear.

Skip it if you do not wear a hat or cap; Repel 100 offers spray-on coverage against biting flies instead.

This fits outdoor users who wear a hat and want an odorless, non-chemical way to trap deerflies near the head. It is a headwear-based patch, not a general spray for exposed skin or other body areas.

#4 · Highest DEET

4. Repel 100 Pump Spray

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

Best for: High-DEET outdoor coverage.

Why it ranks #4: Its 98.11% DEET formula lists biting flies among its targets and provides up to 10 hours of protection, though deer flies are not specified.

A 98.11% DEET formula is the defining feature of Repel 100, offering protection for up to 10 hours in severe insect conditions. Its listed coverage includes biting flies, making this pump spray a broad-coverage option when deer flies share the outdoor setting with other biting pests.

Repel lists biting flies alongside mosquitoes, ticks, gnats, chiggers, and fleas, so one application can address several kinds of outdoor pests. The up-to-10-hour protection is useful for longer outings, while the 4-fluid-ounce pump format is convenient to store with adventure gear. Its DEET concentration is 98.11%, and the supplied material information says it will not damage cotton, wool, or nylon, a helpful consideration for treated clothing.

Skip it if you want a patch that traps deerflies at your hat rather than a broad-spectrum DEET spray; TredNot Deerfly Patches target that use.

Choose Repel 100 if you want long-lasting, high-DEET coverage against several biting insects, including biting flies. Its listing does not specifically name deer flies, so shoppers seeking a deerfly-targeted patch should consider that distinction.

#5 · DEET-Free Spray

5. OFF! Clean Feel Picaridin

• Size: 5 Fl Oz (Pack of 1)
• Form: Aerosol
• Volume: 5 fluid oz

Best for: Fragrance-free everyday spray users.

Why it ranks #5: This fragrance-free picaridin aerosol lists biting flies as targets and offers up to eight hours of protection without DEET.

Picaridin in a fragrance-free, DEET-free aerosol gives OFF! Clean Feel a skin-applied option for people who want biting-fly coverage without a scented spray. The formula is described as quick-drying and non-sticky, and its listed protection lasts up to eight hours when used as directed.

OFF! lists biting flies, mosquitoes, and ticks among the insects this aerosol repels when used as directed, making it relevant when deer flies are part of a broader biting-fly problem. Its picaridin formula is fragrance-free, dries quickly, and is described as non-greasy and non-sticky, supporting everyday application without sticky residue. The 5-ounce aerosol is easy to apply, but the directions say to spread it evenly with hands for maximum protection.

Skip it if you want a patch that traps deerflies at your cap; TredNot Deerfly Patches offer that targeted, non-spray approach.

This suits shoppers seeking a fragrance-free, DEET-free aerosol for everyday coverage that includes biting flies. It requires even spreading by hand for maximum protection and does not specifically name deer flies in its claims.

6. Cutter Backwoods 25% DEET

• Size: 6 oz (Pack of 2)

Why it ranks #6: The 25% DEET, sweat-resistant aerosol lists biting flies among its targets and offers mosquito protection for up to 10 hours.

A sweat-resistant formula is the key advantage of Cutter Backwoods for active outings in warm, humid conditions. Its 25% DEET aerosol is listed to repel biting flies as well as mosquitoes, ticks, gnats, chiggers, and fleas, with mosquito protection lasting up to 10 hours.

Cutter lists biting flies among the insects repelled, which makes this 6-ounce aerosol relevant when deer flies are part of a mixed-bug outdoor setting. The 25% DEET formula provides up to 10 hours of mosquito protection, and its sweat-resistant claim supports active use in warm, humid conditions. The two-pack gives users another can for later or a separate outing. This is broad insect coverage, not a product description that specifically singles out deer flies.

Skip it if you need a listed 40% DEET formula and explicit deerfly coverage; Cutter Backwoods High DEET 11 Oz supplies both.

This two-pack suits active outdoor users who want sweat-resistant coverage against several insects, including biting flies. The stated 10-hour duration applies to mosquitoes, and the listing does not specifically name deer flies.

#7

7. Sawyer MAXI DEET

• Size: 4 Fl Oz (Pack of 2)
• Form: Liquid
• Volume: 4 fluid oz

Best for: High-density insect-area coverage.

Why it ranks #7: Its low-odor 100% DEET formula lists black flies and gnats and works for up to 10 hours, but does not specifically name deer flies.

Sawyer’s 100% DEET, low-odor formula is intended for areas with extreme bug density and offers up to 10 hours of protection. Its listed targets include black flies and gnats, along with mosquitoes, ticks, chiggers, and fleas, while two 4-ounce bottles provide separate applications or storage options.

The low-odor formula is listed for use on exposed skin, mosquito nets, head nets, and clothing, giving buyers several application surfaces for high-bug-density outings. Sawyer says protection lasts up to 10 hours and includes black flies, gnats, ticks, chiggers, and fleas. The pack contains two 4-ounce spray bottles, which can be kept with separate gear. The supplied claims do not specifically identify deer flies, so the fly coverage is broader rather than deerfly-specific.

Skip it if you need deer flies explicitly named among repelled insects; Cutter Backwoods High DEET 11 Oz lists them directly.

Choose Sawyer for high-insect-density settings where low odor, extended protection, and multiple application surfaces are useful. Note its clothing-material restriction and that its supplied claims do not specifically name deer flies.

#8

8. OFF! Deep Woods 25% DEET

• Size: 6 oz (Pack of 1)
• Form: Aerosol
• Volume: 6 fluid oz

Best for: Camping and fishing spray coverage.

Why it ranks #8: This 25% DEET aerosol lists biting flies and offers broad coverage, but deer flies are not identified among its listed targets.

A continuous-sweeping aerosol application makes OFF! Deep Woods convenient for covering exposed areas before camping, fishing, hiking, or hunting. Its 25% DEET formula lists biting flies, mosquitoes, ticks, gnats, and chiggers among its targets, although the supplied claims do not specifically name deer flies.

The aerosol is applied by holding it 6 to 8 inches from skin and spraying in a sweeping motion, a straightforward method for broad coverage on outdoor outings. Its 25% DEET formula targets biting flies, ticks, gnats, chiggers, and mosquitoes, including those that may carry named diseases. OFF! also describes the spray as non-greasy. The 6-ounce can is portable for taking along, but the product listing does not single out deer flies.

Skip it if you want deer flies explicitly named on the label information; Cutter Backwoods High DEET 11 Oz lists them directly.

This fits campers, anglers, hikers, and hunters seeking broad DEET aerosol coverage that includes biting flies. Because deer flies are not specifically named in the supplied claims, it is a less direct match for that target.

#9

9. OFF! Deep Woods Sportsmen

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

Best for: Compact high-DEET travel spritz.

Why it ranks #9: The 98.25% DEET spritz lists biting flies and up to 10 hours of protection, but the one-ounce size and lack of deerfly-specific claims limit its fit.

The 1-ounce spritz format makes OFF! Deep Woods Sportsmen a compact choice for outdoor enthusiasts who want 98.25% DEET protection in a small container. Its claims cover biting flies, mosquitoes, ticks, chiggers, and fleas, with up to 10 hours of protection, though deer flies are not named specifically.

The 98.25% DEET formula is listed for long-lasting protection against mosquitoes and biting flies, with additional coverage for ticks, chiggers, and fleas. Its 1-ounce liquid spritz occupies a compact format for summer travel and backpacking, and the formula is described as odorless with no fragrance. The supplied facts state protection for up to 10 hours. Since the claims say biting flies generally rather than deer flies specifically, buyers seeking explicit deerfly coverage should note that distinction.

Skip it if you want a product that explicitly names deer flies; Cutter Backwoods High DEET 11 Oz does so and comes as an aerosol.

This compact spritz suits travelers and backpackers seeking high-DEET protection in a small container, with claims that include biting flies. Its supplied description does not specifically name deer flies, a relevant boundary for targeted buying.

#10

10. OFF! Deep Woods Dry

• Size: 4 oz (Pack of 2)
• Form: Aerosol
• Volume: 4 fluid oz

Best for: Two-can camping and hiking supply.

Why it ranks #10: This two-pack contains 25% DEET and lists mosquitoes and ticks, but its supplied target list does not identify biting flies or deer flies.

Two 4-ounce aerosol cans give OFF! Deep Woods Dry a practical supply format for camping, hiking, and other outdoor activities. The 25% DEET formula provides up to eight hours of mosquito protection, and the listing also identifies protection against ticks, making it a broad outdoor option rather than a deerfly-specific product.

The 25% DEET formula is described as providing up to eight hours of mosquito protection, while the listing also names ticks; its additional description emphasizes non-oily, non-greasy wear. Two 4-ounce cans provide separate containers for storing with outdoor gear or taking on different outings. The directions specify holding the aerosol 6 to 8 inches from skin or clothing and spraying in a sweeping motion, a useful routine for broad application.

Skip it if you need an explicitly listed biting-fly repellent; OFF! Deep Woods 6 oz names biting flies among its targets.

Consider this two-can option for camping or hiking when mosquito protection and a non-greasy feel matter. Its supplied claims focus on mosquitoes and ticks rather than biting flies, so it is not the clearest deerfly-specific pick.
