I wish I hadn’t promised that I’d never mention bugs on my blog again, because last weekend a friend gave me a tip that just BLEW MY MIND. And it had to do with repelling flies with three things you have on hand RIGHT NOW. So if you don’t want to know, I’ll understand– simply cover your ears and say “lalalala” until the post is over. But for the rest of you, read on to learn my friend’s trick for how to keep your next outdoor party fly-free!
One of my college BFFs came for a visit recently and after sitting down for a nice dinner on the deck we started to get bombarded with that pesky summer staple– FLIES.
“Don’t you know the fly trick?” — college BFF
“What fly trick?” — me
“The pennies in the cup fly trick.” — college BFF
I’d heard rumors of people using plastic baggies filled with water and pennies to repel flies in their home, but hadn’t thought to take the action outdoors. So I followed her directions and filled up three glasses with water and a few pennies (about 4-5), placed them around the food, and watched. We watched the flies come in to land, see the water, and turn around and ZOOM AWAY.
Glass + Water + Pennies = crazy fly repelling abilities.
It was unreal. I’d say it reduced the flies by about 90%. At one point we looked up and the flies were just sitting on the deck railing staring at all the food they couldn’t ruin.
RE-ENACTMENT:
We’ve used the ‘fly trick’ each outdoor meal since. The more glasses full of water, the better the fly repelling ability. The kids think this is the coolest thing ever and have learned not to drink the water with the pennies in it.
It was also mentioned that older (tarnished?) pennies work best, though I don’t have evidence to back it up. If the trick isn’t working for you, try using older pennies.
Apparently it has something to do with flies thinking the pennies were compound eyes of a much larger bug looking back at them. To us, they just look like coppery decorations that glittered in the sunlight. “They’re so PRETTY!” my kids sighed
For more ideas for repelling bugs, be sure to read how to use essential oils to repel everything from mosquitoes to ticks to lice. And then I won’t talk about bugs EVER AGAIN. Summer’s almost over and then I’ll go back to pumpkins and room makeovers, I promise. Probably. 😉
But until then, don’t be surprised if you come over to visit and there’s penny filled cups everywhere with sad looking flies lined up on the railing.
Did you know this trick? KABOOM, right? Give it a try and let me know if it works for you too!
That’s wild!!! I had NO idea! Will definitely try next outdoor dinner. Thanks!
I always heard that the reason for the copper is to retard algae growth…keep the water clean, like copper pipes. The bags and jars of water act like mirrors to confuse the flies who have very sensitive eyesight, and the structure of their eyes act like a prism, so moving, reflected light makes it difficult for them to figure out where to land. So the pennies really are not necessary if it is just for a day or so, and would need to be old as new pennies do not have enough copper.
I don’t think pennies contain much copper these days.
I tried it but no luck with Aussie flies
So sorry! I have a feeling Aussie flies are much tougher than those in the States… I mean, judging from the other animals you have there! Eeek!
One method that works, in addition to the penny water bags, is the use of an old CD. If you have two, that’s even better. Most CDs have one reflective side. Using two creates a dual effect and allows natural sunlight (when you have it) to bounce light in a flickering fashion that scares the flies away!!! A nice breeze makes your summer day look like a daytime disco party! LOL Enjoy the homemade repellent!!!
That is GENIUS. Doing this immediately ….and the reenactment? Adorable!
Great tip!! Can’t wait to try it!! Thanks 🙂
The reenactment is hilarious! I have heard about the penny trick before but never tried it. Here in AZ we are not bothered by flies much.
Boy have you made my day…thank you for the tip!!
Carrie,
I love your blog. Fantastic (and helpful) post about how to keep flies away. I love how you suggested from the post to visit your blog. Great strategy.
Definitely going to share this for you.
Make it an awesome day.

dont stop i want to know how to safely get rid of bugs
Here is Houston, everytime we sit down for a meal, there are the flies!!! I have seen the plastic bag of water with pennies in it in some of the older mom and pop restaurants and completely forgot about it. I definitely will be trying this next weekend when my husband and I sit outside again! Thanks for the tip!
I live in FL, which feels like the bug capitol of the world..at least to me 🙂 We will use this handy trick from now on! Thanks so much for sharing! Pinning:)
I’m not sure where the person lives in Az that she is bothered by flies much. I live in Mesa, AZ and we have flies all the time in our backyard. We are out there for a few minutes and say the heck with it and go back in the house. Maybe that’s it she stays in the house. I am going to do this right now so we can go out back and relax until it gets too hot today. Thank you so much for the info. You can talk about bugs anything as long as you can tell me how to get rid of them.
How funny! I forgot about this tip!! Thank you so much for sharing, we are having a horrible problem right now so I’m going to give it a shot. Can’t wait to see the timid flies. Your pictures are beautiful BTW.
I will be using this the next time we outside!
I use pre-1982 pennies to help keep my bird bath clean. They have more copper. Works well. Will try this idea.
Fantastic tip, thanks! I had no idea about the dates and percentage of copper!
OK. I’m old and I know a lot of tricks. And I’ve never heard of this. NEVER! I’m going to have to plan a meal outdoors just to test it out.
How did it work out? Curious!!
I live in a small homestead with sheep/rabbits/ducks/chickens…and lay smack dab in the middle of a couple vow farms..the flies are insane! I’m wondering if I could use this trick in a mason jar and hang them from my porch ceiling?
All these years of pesky flies and all I needed was water and pennies? Who knew! Now just to get rid of those pesky mosquitos and we are set. Thanks for the tip!
One of the ladies in her comment said something about the eye sight of flies. She is probably right.
I will definitely try this. I sooooo wish it would work for mosquitoes, too, hate those things SO much ! ! When we visit our daughter in northern Canada I wear net top & bottom, to totally cover me, (they sell these things for gardeners, fishermen) I don’t care if I look like a dork, I will NOT be eaten alive ! ! My skin reacts to their bites, the ‘poison’ they put into you never seems to go away, I can scratch the same spot, always a hard bump, for years ! ! really ugly & weird ! !
I heard about this, but never tried it personally, but I do plan to give it a try this summer. Thanks!
One method that works, in addition to the penny water bags, is the use of an old CD. If you have two, that’s even better. Most CDs have one reflective side. Using two creates a dual effect and allows natural sunlight (when you have it) to bounce light in a flickering fashion that scares the flies away!!! A nice breeze makes your summer day look like a daytime disco party! The flies just “dance” away… LOL Enjoy the homemade repellent!!!
I have questions about the CD method. Do you just lay the CD’s on the table? Or do you hang them up? And, if using two, do you recommend keeping them close to each other (for the two-bug-eyes effect)? Thank you for breaking this down for me. 🙂 I can get lost easily.
This actually worked! I just did it and every fly has just disappeared! Crazy!
Amazing! No flies at my front door screen after I hung up a storage size baggie with a few pennies! Dozen of flies swarmed my screen door when I fryed shrimp and sprayed smelly chlorax at the screen but they kept coming until I googled “how to keep flies away”. Also put a clear water glass with pennys on table tray outside by the screen door.
I’ve tried the pennies in the bag, here in PA. Sorry to say, it did not work for me😞. I will say that using baby powder for Ants, has helped us!!! They won’t come near our entry ways.
I tried a 1/2cup Pyrex dish with water and about 5 pennies, old and current. There were a couple flying around when I went outside with my dinner. Got tired of shooing them away before every bite and googled ideas. Funny thing is…as soon as I put the dish out I was actually noticing MORE flies and they were much more persistent! The dish was right next to my plate too.
I’ll have to give it another try with a few more dishes or glasses. Has anyone noticed improvements with certain glass shapes over others? I would think a stemmed wine glass might be better since the pennies would be elevated off of a table’s surface.
One of the down sides to living in the suburbs where everyone and their mother owns a dog… 😒
Prevention should be the first step before you cause drawing no-see-ums, bees, flies, etc. to share you and your drinks.
Sure sprays and stuff work some what, however most bugs are attracted to open drink containers then to your body.
Odor and smells seems to be the attraction for bothersome bugs, so by having any drink container completely covered helps by not advertising it. Ever run from a Bee or Wasp?
A solid lid is a great way to reduce attracting things, no straws, no sippy lids. One that I found is made in the USA at Pittsburgh Pa works great, just Google drink container protector and you’ll find a bunch.
I even use one at work to keep other people’s germs from my coffee mug.
Oh YAY!!! I am SO doing this…Right now! Thank you so very much…I love being outside when it isn’t 100 degrees…but the insects…flies…I can def do without. Surely hope this helps. Besides, what do I have to lose right? Thanx for sharing this post….I’m onto the next post about bugs {& other creepy crawlers) now! 🙂
Flies and wasps were spoiling a sunny afternoon in Stanmore London
Found your post
tried the pennies in a jar of water it actually works
I have lived in New England all my life – Mom, Grandmothers and Aunts all from Mass, New Hampshire and Vermont…how have I never seen this trick? Love it! Everyone hates “useless” pennies but I always pick them up! Now they have a real “value”! Thanks! Paris in Mass (live in the country and have indoor pet bunnies)
Cano u use paper cups or does it have to be glass for reflection
It has to be glass. 🙂
THANKS
Oh my Goodness sakes! I had just sat at my dinner table preparing to do some work, well along comes 2 UNWELCOME little pests. Flying around me and l happen to bed on the phone and ended up telling at the person on the phone. I told I’m sorry, but I’m actually telling at the flies trying to sit in my face. She felt bad for me. So I got off the phone and looked online to see what I can do besides spraying them with bleach. And lo and behold! The pennies in a cup trick. I have to say, what flies? So awesome, I have no idea where they both went but it sure worked wonders. Now I can do my work in peace. Thank you!!!
