There’s nothing worse than inviting guests around for an outdoor party in the backyard and being bombarded by flies and other winged insects while you try to relax and eat.
So, after months of being attacked by flies at BBQs and picnics, I’ve been scouring the net for how to keep flies away from food at an outdoor party.
Here’s a list of the ways that you can repel those flies so that they’ll buzz off and leave your party in peace.
How to Keep Flies Away From Food at an Outdoor Party
1. Set Up Electric Fans
Although a fly’s size makes it nigh on impossible to swat, it also means they can’t fly well in wind.

If you have a covered patio, consider installing a ceiling fan. If not, some portable electric fans could easily keep those pesky insects away, plus they’ll keep you cooler in the summer months.
You need a nice, high-powered fan like this one on Amazon.
2. Use Citrus Scents
Flies hate the scent of lemons, so if you can spare a couple after you’ve served the gin and tonics, slice them in half and create some tasteful table decorations with them.
If you really want to double down on the scents you’ll love but the flies will hate, stuff cloves into the flesh of the sliced lemons.
Bundle a whole bunch of these herbs into a vase for a centerpiece that looks great and repels insects too.
3. Wear Bug Repellents
Chances are you’ve used mosquito repellent at some point in your life to keep those biters away on vacation.
But you’re not limited to repelling just mosquitoes; there are also repellents for creating a no-fly zone around your body.
If you can’t stand the smell, look for all-natural repellents that are made from the same essential oils we’ve listed out above. They can be better for the skin too.
4. Use Scent Diffusers or Candles
That’s right, yet another method that involves using those scents that flies can’t stand. If you choose the right fragrance, a reed diffuser can drive away flies.
Or, if you’re a smart home enthusiast, you can pick up electric scent diffusers that hook up to your Wi-Fi like a remote control anti-aircraft system.
And you guessed it; the best thing to fill these diffusers with is one of those essential oils that these insects hate so much.
Candles can work too, though they’re obviously less effective outdoors if there’s a strong wind.
Citronella candles are the scent of choice for driving away mosquitoes, but did you know that they’ll swat flies away too?
If you and your party are eating in a porch area with lots of protection from the breeze, then fire up a candle in the corner and you should see fewer unwelcome intrusions.
5. Use Papaya Leaves
An informal study conducted by two students of the Modern English School in Mumbai found that papaya leaves may well be effective as a mosquito repellent.
They mixed the extract of papaya leaves in a candle, and once they burned it, it worked well as a repellent.
“We have seen that the chemicals used to drive away mosquitoes are not environment friendly. While working on various herbal solutions, we found that leaves of papaya tree can work as mosquito repellent,” said Neha and Divya.Business Standard
6. Grow Carnivorous Plants
Carnivorous plants – think Venus Fly Trap – can be a great natural solution to your fly problem. Though they’re not a preventative solution, they’re great to have around the house or porch and will soon start to reduce your resident fly population.
As an uncommon house plant, they also look awesome and should generate a few comments from your guests.
And, although they’re not the easiest plant to buy online, you can buy them on Amazon – just click the image below!
7. Blindside Those Flies
I’ve seen reports that you can hang a food bag half-filled with water to distract and drive away flies in well-lit yards. Supposedly, it has something to do with the way that the light reflects through the water, confusing their vision.
With approximately 8,000 lenses within each eye, flies have incredible vision in every direction, but stray light rays can easily interfere with this ability.
Some bloggers have reported success with a similar method that uses glasses filled with water and a few pennies sitting at the bottom.
Just remind your guests not to drink the water or you’ll have a much bigger problem than how to keep flies away from food at your party.
8. Treat Your Doorways and Window Frames
If you’re hosting the party on your porch close to the house entrance, you can treat the doorways and window frames with Pyrethrin-based insecticides or other natural forms of repellent to discourage flies from food at the party.
Pyrethrin is a product made from the chrysanthemum flower and works against common house flies, gnats, and other insects too. Like a silent assassin, it won’t leave any traces, at least, not on your doors or windows.
The product in the image below, ‘Mosquito Magician’, is made from a blend of essential oils, including Citronella, Garlic Oil, Rosemary, Lemongrass, Cedarwood, and Geraniol.
It can be used outdoors around the home, garden, patio, and pool, and lasts for up to 2 weeks.
You simply mix 4 oz in 1 gallon of water and spray it around with a pump sprayer, fogger, or even a commercial backpack sprayer.
9. Cover Food and Throw Out Waste
During any outdoor party, you’re bound to accumulate waste. Empty plates, used cutlery, spent food packaging, and all sorts of other bits and pieces that you might be tempted to deal with once the guests have gone home.
But flies are attracted to food scraps and you’ll only increase the chances of having a swarm descend on you and your party.
Keep food covered once it comes off the BBQ and you should see fewer unwanted visitors.
10. Make Your Own Fly Trap
Sure, you can buy fly traps from most home stores, but they’re usually pretty unsightly.
Nothing spoils an appetite more than a hanging sticky trap filled with dead flies out in the open. UV light traps aren’t much better; nobody wants to smell cooked insects rather than the smell of cooking BBQ foods.
But don’t worry, you can easily make your own fly traps to keep flies away from food at an outdoor party with a few things you can normally find in your kitchen cupboard.
- Take a mason jar or similar container.
- Add some wine or vinegar.
- Cover the opening with plastic wrap.
- Punch through a few holes in the plastic.
- Flies will smell the liquid and enter, but are unable to escape, leaving you and your guests to enjoy the real food in peace.
You don’t even need a mason jar for this quick hack. Just take a used soda bottle and you’ll have your own fly jail in no time. Check out this handy YouTube video I found that shows you how to make your own fly trap:
11. Ultrasonic Pest Repeller
Ultrasonic pest repellers are a simple plug-in-and-go type system, some with electromagnetic and ultrasonic wave technology. The waves disturb the pest’s central nervous system and will drive them away, no chemicals required.
They’re generally easy to use, all you need is a wall socket and plug it in. They don’t make any noise so you can use them indoors and outdoors (in a covered, dry area such as a patio).
They work for flies, but also other insects and even rodents!
These are a good option for keeping flies away from food as they’re non-toxic, eco-friendly, and humane.
12. Use a Fly Swatter
If all else fails, you could always turn to the trusty fly swatter to ‘take care’ of those flies once and for all.
Probably a last resort, given that you don’t want dead flies littering your party table, but you can pick up electrified swatters these days to make sure that you never miss a shot.
13. Try a Cattle Dog
This solution for keeping flies away from food might sound a bit silly, but my little cattle dog was the best fly repellent of all. She’d tirelessly chase flies around and was the best at catching them too!
Not only does it keep an energetic dog like the cattle dog entertained, she actually made a big difference to the number of flies around our party.
When we went camping on the beach, she won the march fly catching competition with 12 march flies in 2 minutes. None of us could beat here.
Mind you, I don’t normally go around killing animals without reason but the number of (very painful) march fly bites left us no choice. Except go home, I suppose.
