You finally get a warm day, the grill’s going, lemonade in hand, and you’re ready to soak up some fresh air. Then it starts, the low, relentless buzzing near your ear. A few flies at first, then more.
And just like that, your chill backyard moment turns into an annoying swatting match.
Why does it always happen when you’re just trying to relax?
The truth is, flies are surprisingly smart about where they hang out. They’re not just random pests, they’re opportunists.
Give them the scent of food, moisture, or anything slightly rotten, and they’ll set up camp like it’s their own private retreat.
But you’re not stuck with them. With the right mix of natural repellents, smart cleaning habits, and a couple of clever traps (some are weirdly satisfying to watch, not gonna lie), you can take your yard back.
Let’s talk about what’s attracting them in the first place because if you can figure that out, you’re already halfway to winning the battle.
What Attracts Flies to Your Yard in the First Place?
Here’s the thing: flies aren’t out to get you. They’re just wired to chase smells, moisture, and decay.
If your outdoor space checks any of those boxes, it’s like putting up a neon sign that says “All You Can Eat.”
Here’s what usually draws them in:
- Food scraps and crumbs — from BBQs, picnics, pet bowls, or forgotten snack plates.
- Uncovered trash or recycling bins — even “empty” ones still smell delicious to a fly.
- Standing water — birdbaths, clogged gutters, overwatered planters, and even puddles can be breeding grounds.
- Compost piles — especially when fruit peels or leftovers are exposed.
- Pet waste — yep, it’s gross, but flies love it. That forgotten spot behind the shed? They haven’t.
Then there’s the seasonal effect, flies love heat. Warm weather speeds up their life cycle, which means they multiply faster in the summer.
You might notice they’re almost nonexistent in winter, only to show up like clockwork as soon as spring hits.
And if you’ve got chickens, horses, or a garden with decaying mulch? You’re their favorite neighbor.
Let me guess, you’re thinking, “So I just have to live like a sterile monk outside?” Not at all. You can keep your garden, grill, and even your compost pile.
The trick is making it less appealing… and we’re about to get into how.
Natural Fly Repellents That Actually Work (No Fancy Stuff Required)
You don’t need a chemical fogger or some industrial-grade poison to get flies to back off. In fact, most of what you need might already be in your pantry or growing in your garden. Flies are picky about smells certain scents send them packing fast.
Here are a few of the most effective natural fly repellents that won’t make your backyard smell like a science lab:
1. Basil, Mint, and Lavender – The Smells They Hate
Plant herbs like basil, mint, and lavender near seating areas, doorways, or food prep zones.
These herbs give off strong natural oils that flies can’t stand. Bonus? They smell amazing to humans and attract pollinators like bees and butterflies.
You can use them fresh or dried, or crush the leaves and scatter them where flies tend to linger.
Amazon picks:
- Live Basil Herb Plant – 2 Pack – Easy to grow in pots or garden beds
- Lavender Essential Oil – Mix with water for a fly-repelling spray
2. Citrus Clove Trick (It’s Weirdly Effective)
Here’s a grandma-approved trick: slice a lemon in half and stick whole cloves into the flesh. Place the clove-studded halves on your patio table or windowsill.
The combo of citrus and clove oils makes flies turn around mid-air.
It’s oddly satisfying to see them avoid it like it’s cursed.
Amazon pick:
- Whole Cloves – Use for both fly repellent and seasonal baking, win-win
3. Apple Cider Vinegar Trap
This one’s more about luring and trapping than repelling, but still counts.
Pour some apple cider vinegar into a small jar, add a drop of dish soap (it breaks the surface tension), and cover the jar with plastic wrap poked with holes.
Flies get in, can’t get out. It’s simple, cheap, and satisfying.
Amazon pick:
- Bragg Organic Apple Cider Vinegar – Good for this and your gut health
4. Eucalyptus and Citronella Oils
Both eucalyptus and citronella are strong deterrents. Add a few drops to a spray bottle filled with water and a touch of alcohol (like witch hazel or vodka) to create a mist.
Spray around doorways, patio furniture, and trash areas.

Homemade Fly Traps That Work While You Chill Outside
Not every fly problem needs a commercial gadget. Sometimes the most effective traps are the low-tech, low-budget, kind-of-genius ones you make yourself.
These setups work quietly in the background while you sip your iced tea, no buzzing zappers, no chemicals, no fuss.
1. Water Bag Trick (Seriously, Just a Ziplock)
You’ve probably seen this in old diners or someone’s grandma’s porch, a plastic bag half-filled with water, hung near doorways or patios.
Some folks even add pennies to it. It sounds bizarre, but the light refraction confuses the fly’s vision and makes them stay away.
Does it work on every fly? Not always. But it’s cheap, weird, and works often enough that it’s become a backyard classic.
Amazon pick:
Hefty Slider Quart Freezer Bags – Strong enough to hang without leaking
2. Bottle Trap for Fruit Flies and Small Nuisance Flies
Take a used plastic bottle, cut off the top third, and invert it back into the base like a funnel.
Pour in something sweet and sticky, juice, soda, or overripe fruit, and let it sit near the fly zone. Once they crawl in, they can’t figure out how to get out.
For extra punch, add a few drops of dish soap.
Amazon pick:
12-Pack Clear Plastic Bottles with Caps – Great for DIY traps or storage
3. Beer or Wine Trap (The Flies Love a Party)
Leftover wine? Flat beer? Don’t pour it out. Put it in a cup or jar with plastic wrap over the top and poke holes in it.
Flies are drawn to fermented things. It’s like happy hour for them… until it’s not.
You’d be surprised how many you’ll trap in a single afternoon.

Where Flies Breed (And How to Shut It Down at the Source)
If you’re constantly swatting flies every time you step outside, you’re not just dealing with a random infestation; you’ve got an open invitation somewhere nearby.
And flies aren’t exactly picky guests.
They’ll party in compost bins, soggy trash bags, pet poop, or even that old flowerpot saucer you forgot to empty.
Here’s the thing: most fly problems aren’t really about flies. They’re about what flies want moisture, decay, food scraps, and warm places to lay eggs.
Take a walk around your backyard or porch and check for these usual suspects:
- Open garbage bins: If your outdoor trash cans don’t have tight-fitting lids, you’re basically hosting a buffet.
- Pet waste: Yep, even that one time your dog went in the corner of the yard and you didn’t pick it up right away, flies remember.
- Compost gone funky: Composting is amazing, but it has to be well-managed. Otherwise, it’s a five-star breeding ground.
- Standing water: Birdbaths, plant saucers, forgotten buckets. If water sits for more than a couple of days, flies (and mosquitoes) will come running.
What helps?
- Tighten up trash lids. Get ones with a latch or bungee cords if raccoons are also a problem.
- Scoop pet waste daily. A pooper scooper and a sealed bin go a long way.
- Balance compost with dry materials like leaves or shredded newspaper to keep it from going slimy.
- Drain standing water every couple of days. Or, use mosquito dunks if you can’t empty the source.
Amazon picks:
- Animal-Proof Trash Can with Lid – Keeps smells in and flies out
- Nature’s Miracle Jaw Scoop Pooper Scooper – Handy for everyday cleanup
- Mosquito Dunks – 6 Pack – Prevent both mosquitoes and flies from breeding in water
Are Fly Zappers Worth It? (Short Answer: Sometimes)
Okay, let’s settle this. Do those electric fly zappers actually work, or are they just glowing blue gimmicks?
Short answer? They can help but only in the right setting.
Fly zappers (aka bug zappers) work by attracting flying insects with ultraviolet light. Once the fly touches the electrified grid, zap problem solved.
But here’s the catch: not all flies are drawn to light. Houseflies are a little more complicated.
They’re attracted to smell and food more than they are to UV light, which means a zapper alone won’t wipe out your fly problem.
But paired with bait or used at night around patios? They can absolutely reduce the buzzing chaos.
If you’re going to try one, go for a model that:
- Covers a decent range (half an acre or more)
- Can hang or stand freely
- Has an easy-to-clean tray for all the “zap remains” (gross but necessary)
- Doesn’t require frequent bulb replacements
And hey, they’re kind of satisfying. That little crack! sound is weirdly rewarding when you’ve been dealing with flies all day.
Amazon pick:
GOOTOP Bug Zapper Electronic Insect Killer – Covers 1 acre, weatherproof, and gets consistent reviews from fly-haters everywhere.
Homemade Fly Traps That Actually Work (Because Store-Bought Isn’t Always Better)
You don’t always need a fancy contraption to catch flies. Some of the best fly traps you’ll ever use are made with stuff sitting in your kitchen right now.
And you know what? These homemade traps can be oddly satisfying to put together like a weird science experiment that actually works.
Here are a few tried-and-true recipes that draw flies in like magnets:
1. Apple Cider Vinegar Trap
- What you need: A jar, plastic wrap, rubber band, and apple cider vinegar.
- How to use it: Pour a bit of vinegar into the jar, cover the top with plastic wrap, poke a few holes, and secure it with the band. The smell attracts flies, the plastic traps them.
- Why it works: Fermented sweetness is irresistible to houseflies, and once they’re in, they rarely find their way out.
2. Fruit Trap
- What you need: Overripe fruit, a jar, paper funnel.
- How to use it: Place fruit in the jar and insert a paper funnel into the opening. Flies get in, can’t get out.
- Best for: Fruit flies and smaller outdoor flies.
3. Dish Soap + Vinegar Bowl
- What you need: Apple cider vinegar and a few drops of dish soap.
- How to use it: Mix in a bowl and leave it uncovered. The soap breaks the surface tension, so flies sink instead of floating.
- Bonus tip: Add a drop of honey or overripe banana if you want to increase the attraction factor.
These traps aren’t just cheap and chemical-free, they’re also oddly gratifying when you see how many flies they catch overnight. Seriously, it’s like fly revenge in a mason jar.
Amazon pick for supplies:
- Wide Mouth Mason Jars – 6 Pack – Great for traps and everyday kitchen use
- Bragg Organic Apple Cider Vinegar – The gold standard for ACV-based fly traps
- Dawn Ultra Dishwashing Liquid – Cuts grease and catches flies
Citronella, Lavender, and Other Natural Fly Repellents That Don’t Smell Like Death
Not everyone wants their yard to smell like harsh chemicals or bug spray. And you really shouldn’t have to choose between flies or fumes.
Luckily, nature gives us some surprisingly powerful fly repellents that smell, well… like something you’d actually want in a candle.
Let’s break down a few plants and essential oils that flies absolutely hate:
Citronella
It’s the classic for a reason. Citronella oil masks scents that attract flies like sweat, garbage, or food, and keeps them away without killing them.
You can burn citronella candles, plant citronella grass around patios, or use oil in a spray bottle diluted with water.
Lavender
Flies can’t stand it, and neither can mosquitoes, moths, or gnats. Meanwhile, you get a relaxing, spa-like scent every time the breeze blows.
You can use dried lavender bunches or mix a few drops of essential oil with water and spritz around doorways, picnic tables, or patio cushions.
Basil, Mint, and Rosemary
Herbs do more than season your pasta. They’re natural repellents, and they grow well in pots or garden beds.
Place a few around your outdoor seating area and they’ll pull double duty: decoration + fly protection.
DIY Natural Spray Recipe
- 1 cup water
- 2 tablespoons witch hazel or rubbing alcohol
- 10–15 drops essential oils (lavender, citronella, eucalyptus, peppermint all work)
Shake in a spray bottle and mist your clothes, screens, or chairs. Just make sure to spot-test fabrics first.
Amazon picks:
- Murphy’s Naturals Citronella Candle – Long burn time, smells good, and made with natural soy wax
- Majestic Pure Lavender Essential Oil – Great for DIY sprays or diffusers
How to Keep Flies Out of the Trash (Because That’s Their Favorite Buffet)
Let’s be honest, your trash is practically Disneyland for flies. It smells like heaven (to them), it’s full of leftovers, and there’s always something new.
If you’ve ever lifted your outdoor bin lid and seen a mini fly swarm inside, you know how fast things can spiral.
So how do you keep them out?
Start with the bin itself:
- Always close the lid tightly – even a small crack is an invitation.
- Clean the bin weekly – hot water + vinegar or dish soap can scrub away old residue.
- Line the bottom with baking soda – it helps absorb odors and moisture (which flies love).
What goes into the trash matters too:
- Double-bag anything smelly – think meat scraps, diapers, seafood, etc.
- Freeze food waste – it sounds extra, but if pickup day is far away, tossing fish bones or spoiled meat in the freezer prevents the stink from ever starting.
- Don’t overstuff – when the lid can’t close, the fly party begins.
Bonus tip? Keep bins in the shade.
Sunlight heats up your trash, speeds up decomposition, and makes it even more tempting for flies.
A cooler bin equals a less smelly bin, and that makes a big difference.
Amazon pick:
Wicker-Style Hideaway Trash Can with Secure Latching Lid – Flies hate it. You’ll love it. Durable, sealed, and doesn’t pop open every time the wind blows.
What NOT to Do (Fly Mistakes That Backfire)
It’s easy to go into fly-fighting mode and start throwing every spray, trap, or internet hack at the problem. But here’s the thing not all solutions are actually helpful. Some even make it worse.
Here’s what not to do when trying to get rid of flies outside:
Don’t just spray and pray
Dousing your patio with bug spray might feel satisfying, but it’s a short-term fix. Flies breed fast.
If you’re not treating the root (decaying matter, standing water, open trash), they’ll be back, with friends.
Don’t rely only on bug zappers
We touched on this earlier, zappers mostly kill moths and other light-loving bugs. Flies? They want the smelly stuff.
Zappers are fine as a backup, but not your main strategy.
Don’t forget to clean your pet areas
Pet poop is fly bait. If your dog’s business stays in the yard, even for a couple days, flies will find it.
Clean it up daily. Same goes for chicken coops and compost bins.
Don’t use sugary bait traps near dining areas
A jar of sugar water or rotting fruit will catch flies… but it’ll also attract more.
If you’re placing traps too close to where you hang out or eat, you’re basically inviting them to dinner. Keep bait traps far away from the action.
Don’t ignore the neighbors’ yard
If you’re doing everything right but flies still won’t quit, take a peek next door. An unclean bin, stagnant kiddie pool, or unkept compost heap next door can undo all your hard work.
Doesn’t mean you have to knock on their door with a fly swatter, but it helps to know what you’re up against.
Amazon pick:
Outdoor Fly Trap System – Attracts flies away from where you eat. Uses natural lures, not sugar or stink bombs.
Plants That Tell Flies: “No Thanks.”
Some plants don’t just sit there looking pretty, they actually work for a living. Certain herbs and flowers give off smells that flies (and other pests) hate.
Adding these to your outdoor space can create a kind of natural barrier, especially if you place them in key spots like near doors, tables, or garbage bins.
Here are a few plant MVPs that send flies packing:
Basil
Flies can’t stand the strong scent of basil. You can grow it in pots near your outdoor dining area, and you get bonus points because it’s delicious in everything from salads to pasta.
Fresh, functional, and surprisingly fierce.
Mint
Strong, fresh, and super effective. Mint grows fast (sometimes too fast), but it’s great for repelling flies and other bugs like ants.
Keep it in containers to avoid it taking over your yard.
Marigolds
These bright flowers contain pyrethrum, which is used in many insect repellents.
They also look cheerful in planters or along walkways, flies hate them, but butterflies love them. Win-win.
Lavender
Ah, lavender. Soothing for us, terrible for flies. The scent confuses and repels them.
Plant it in full sun where it can get a little dry, it thrives in those conditions and keeps the bugs away.
Rosemary
A fly-repelling herb and a barbecue must-have? Yes please. Toss a sprig on the grill while you cook, and the fragrant smoke will act as a natural bug deterrent too.
You don’t need to turn your patio into a jungle. Just a few well-placed planters can make a difference, and they’re way prettier than bug zappers.
12. Outdoor Fly Repellent Sprays That Actually Smell Good
Let’s be honest a lot of outdoor sprays either don’t work, smell like a science lab, or leave everything feeling sticky and weird.
But there are actually some formulas that do the job and won’t make your backyard smell like a chemical factory.
If you’re hosting a cookout, lounging on the patio, or just trying to water your plants without being swarmed, a good fly repellent spray can make the difference between a chill afternoon and a slap-fest.
What to look for in a good spray:
- Plant-based ingredients like citronella, lemongrass, peppermint, or rosemary oil
- Non-greasy finish so your skin (or furniture) doesn’t feel coated
- Safe for kids and pets especially if you’re spraying near eating areas
- Longer-lasting protection some wear off in under an hour
You can use these sprays:
- On your skin or clothes before going outside
- Around doors, windows, or patio perimeters
- Directly on outdoor furniture, umbrellas, or picnic tables
Some people even make their own (we’ll talk about DIY options later), but honestly, when flies are already in beast mode, you want something ready to go.
Amazon pick:
Wondercide Outdoor Pest Control Spray – Ready-to-Use – Plant-based, smells like lemongrass, and you can spray it around the yard without worrying about pets or food areas.
Surprisingly effective on flies, mosquitoes, and even ants.
DIY Essential Oil Fly Repellent Spray (Make It in 5 Minutes)
You don’t have to be a crunchy Pinterest mom to whip up a killer fly spray at home. All it takes is a few essential oils, a spray bottle, and a willingness to shake it before every use.
It’s fast, smells great, and keeps the fly cloud from crashing your porch hangouts.
What you’ll need:
- 1 cup of distilled water
- ¼ cup of witch hazel (or vodka yes, really)
- 15 drops citronella essential oil
- 10 drops eucalyptus oil
- 10 drops lavender oil
- 1 tablespoon white vinegar (optional but helpful for extra stink-fighting power)
- A glass spray bottle (essential oils can break down plastic over time)
How to make it:
Combine all the ingredients in the spray bottle, shake it like a margarita, and you’re good to go.
Spray around doorways, windowsills, picnic tables, or even directly onto outdoor cushions.
You can also spritz it lightly on your clothes, though test a small area first to make sure it doesn’t stain.
A few pro tips:
- Shake before every use the oils separate naturally.
- Reapply every 1–2 hours for outdoor settings.
- Store it in a cool, dark place to keep the oils fresh.
It’s not quite industrial strength, but for daily backyard use, this homemade blend actually does the job and your patio will smell like a spa instead of bug spray.

Are Flies Dangerous? (Spoiler: Yep)
Most people think flies are just annoying, but the truth is… they’re low-key filthy.
Houseflies can carry over 100 pathogens, including E. coli, salmonella, and cholera.
They don’t bite, but they do land on poop, rotting meat, and garbage before hopping over to your sandwich. Gross doesn’t even begin to cover it.
And that’s not even getting into biting flies, like horseflies and stable flies which do bite and can trigger allergic reactions, swelling, or even infection if you scratch too much.
Ever had one follow you around all day while you’re just trying to grill? It’s like being stalked by a tiny vampire.
The danger ramps up if you’ve got pets, young kids, or food left uncovered outdoors. Flies aren’t just annoying, they’re potential health risks.
So while swatting them away feels satisfying, it’s not enough. Control and prevention really matter if you want your yard to stay safe and peaceful.
Final Thoughts: No More Shooing Just Peace and Quiet
Let’s be honest. No one wants to spend a sunny afternoon flailing at flies like they’re practicing interpretive dance.
Whether you’re having drinks on the deck, gardening, or finally hosting that BBQ, you deserve to enjoy your outdoor space without that constant buzz-buzz-buzz in your ear.
What works best? Usually a combo. Clean up messes, keep food sealed, use traps or essential oils, and if you’re dealing with an infestation? Pull out the heavy-duty stuff like Bug Zappers or Fly Bait Stations.
Small changes make a big difference. Tweak your routine, stock up on a few tools, and those outdoor flies? They’ll find somewhere else to hang.
FAQs: Quick Answers to the Fly Drama
Q: Why are there so many flies outside my house?
Usually it’s because something is drawing them in garbage, pet waste, compost, open food, or standing water. They’re always hunting for a place to eat and lay eggs.
Q: Do citronella candles really work?
They can help in small, enclosed spaces like patios, but don’t rely on them alone. Use them with other repellents or traps for better results.
Q: How do I keep flies off my outdoor food during a BBQ?
Use mesh food tents, serve food in covered containers, and keep sugary drinks capped. A fan nearby also helps flies aren’t great fliers in wind.
Q: Are fly traps safe around pets and kids?
Most are, but always check the label. Avoid bait traps where pets can sniff or lick them. Sticky traps should be out of reach.
Q: What scent keeps flies away?
Flies hate essential oils like citronella, lavender, eucalyptus, peppermint, and lemongrass. Mix them with water or witch hazel and spray around.
