Are tiny bugs buzzing around your kitchen driving you crazy? You might be dealing with fruit flies! Don’t worry, these common household pests are more annoying than harmful, and thankfully, getting rid of fruit flies in your house doesn’t require expensive solutions or harsh chemicals. In fact, you likely have everything you need to create effective fruit fly traps right in your kitchen cabinets.
Recently, we experienced a fruit fly invasion at home for the first time in years – a mystery how they appeared! This unexpected situation became the perfect opportunity to put various fruit fly elimination methods to the test. Detailed notes were taken, even a spreadsheet was involved! Now, we’re sharing the best DIY fruit fly traps and simple steps to make them.
These homemade traps are incredibly easy to assemble using natural, everyday ingredients you probably already have. Consider this a super DIY-friendly and chemical-free approach. If you’re feeling compassionate, we’ll even share how to release captured fruit flies outside, offering humane fruit fly trap options. Plus, we’ll cover essential tips to prevent fruit fly infestations from happening in the first place, ensuring a fruit fly-free home.
What Are Fruit Flies? Identifying and Understanding These Pesky Insects
Fruit flies, true to their name, are small flying insects strongly attracted to ripe and fermenting fruits and vegetables. They are also drawn to sugary substances like spilled juice, soda, beer, and wine. You’ll often find them congregating around fruit bowls, garbage disposals, trash cans, and even sink drains. These tiny pests are about the size of a grain of rice and resemble small, tan or brownish houseflies, often with distinctive red eyes. Fruit flies are most prevalent during warmer months, especially summer and late fall, coinciding with fruit harvesting seasons.

A fruit fly problem often starts with just a few individuals hitching a ride into your home on fruits or vegetables from the grocery store. However, female fruit flies are prolific breeders, capable of laying hundreds of eggs in their short lifespan, and these eggs can hatch in as little as 12 hours. They can mature into adults within days, meaning a small initial presence can quickly escalate into a large infestation. This rapid reproduction cycle emphasizes the importance of taking swift action to get rid of fruit flies as soon as you notice them.
Fruit Flies vs. Fungus Gnats vs. Drain Flies: Know Your Kitchen Pests
Fruit flies can easily be confused with other small flying insects commonly found indoors, particularly fungus gnats and drain flies. While all are small and annoying, correctly identifying the pest is crucial for choosing the most effective elimination method. The easiest way to tell them apart is by observing where you see them and what larger insect they visually resemble.
- Fruit flies look like miniature flies. They are typically found near fruit bowls, overripe produce, garbage cans, or any source of fermenting or decaying food.
- Drain flies look like tiny, fuzzy moths. As their name suggests, you’ll usually spot them around sinks, drains, and damp areas.
- Fungus gnats look like small mosquitoes. They are commonly found near houseplants, as they breed in moist potting soil.
If you’re uncertain about the type of pest you’re dealing with, try one of the DIY traps described below. If it attracts the insects in your home, you’ve likely confirmed you have fruit flies!
4 Simple DIY Fruit Fly Traps You Can Make at Home
Getting rid of fruit flies doesn’t have to be complicated or break the bank. You likely already have everything you need to create effective traps. Each of these DIY fruit fly traps follows a basic principle: attract the fruit flies + trap them to prevent escape. We tested the following 4 methods and discovered a clear winner. Since each trap uses common household items, trying more than one won’t hurt! Think of it as a fun little fruit fly science experiment in your own kitchen. Here are 4 easy methods we tested:
- Funnel Trap
- Plastic Wrap Trap
- Dish Soap Trap
- Rotting Fruit Trap
We’ll provide detailed instructions for each method below, along with our findings on their effectiveness. Keep in mind that some traps work faster than others, and it may take several days of consistent trapping to fully eliminate your fruit fly problem.
#1: The Paper Funnel Fruit Fly Trap: A Step-by-Step Guide
This classic fruit fly trap uses a simple paper funnel to guide fruit flies into a container baited with an attractant. The narrow opening at the bottom of the funnel makes it easy for flies to enter but difficult for them to escape.
DIY Fruit Fly Trap With Paper Funnel
Supplies needed:
- Small clear jar, cup, or container, ideally with a narrow opening
- Piece of paper or cardstock
- Tape
- Scissors
- Apple cider vinegar (ACV)
Instructions:
- Choose your container. Select a small, clear container like a clean food jar or a plastic soda bottle. For this method, containers with smaller openings work best to minimize escape routes.
- Add apple cider vinegar. Pour a small amount of apple cider vinegar, old beer, or wine into the bottom of your container. The enticing scent will lure fruit flies into the trap.
- Make your funnel. Shape a piece of paper or cardstock into a cone. The key is to create a very small opening at the tip of the cone, about the size of a grain of rice. Secure the cone shape with tape. You can cut the tip open after taping if it’s easier for you.
- Set your funnel. Place the paper funnel into the opening of your container, with the narrow tip pointing down towards the vinegar. You might need to adjust the funnel shape so it rests securely on the rim of the container without touching the liquid. Ensure there are no gaps around the funnel’s edge where flies could escape.
- Optional Humane Release. If you prefer to release the trapped fruit flies outdoors, carefully carry the entire trap outside without disturbing the funnel (or they’ll fly out!). Once outside, remove the funnel to let the flies escape.
While you can use a store-bought funnel, the opening at the bottom of many commercially available funnels may be too wide, allowing trapped fruit flies to escape. A homemade paper funnel provides a more precisely sized opening for optimal trapping.
#2: The Plastic Wrap Fruit Fly Trap: Easy and Effective
Similar to the funnel trap, the plastic wrap fruit fly trap uses the irresistible smell of apple cider vinegar to attract fruit flies. Flies enter the trap through tiny holes poked in the plastic wrap covering the container, but then struggle to find their way back out.
Supplies needed:
- Small clear jar, cup, or container
- Rubber band
- Plastic wrap or a plastic bag
- Toothpick
- Apple cider vinegar (ACV)
Instructions:
The steps for creating this plastic wrap trap are very similar to the funnel trap. Here’s how:
- Choose your container. Find a small, clear jar, cup, or any similar glass or plastic container. Almost any size container will work, and clarity helps you monitor your trapping success. However, even an opaque container like an old soda or beer can will do the job.
- Add apple cider vinegar. Pour apple cider vinegar into the container. The sweet, fermented scent is a powerful attractant for fruit flies. Old beer or wine are also effective alternatives, but regular white vinegar is not as appealing to them.
- Cover with plastic wrap. Tightly stretch plastic wrap over the opening of your container and secure it firmly with a rubber band. Saran wrap works well, or you can cut a piece from a plastic food storage bag.
- Poke small holes. Use a toothpick to carefully poke a few small holes in the plastic wrap. You don’t need many holes, just a few that are large enough for a fruit fly to enter.
- Optional Humane Release. To release the trapped flies outside, carefully take the trap outdoors without removing the plastic wrap. Then, remove the plastic wrap cover to allow them to fly away.
For a variation on this method, you can also use a metal jar lid instead of plastic wrap. Simply puncture a small hole in a metal lid from a mason jar or old food jar using a hammer and nail, then screw the lid onto the jar after adding the apple cider vinegar.
#3: The Dish Soap Fruit Fly Trap: The Simplest Solution
This fruit fly trap is incredibly simple and doesn’t require creating any covers or funnels. Instead, it uses the principle of surface tension disruption with dish soap to trap fruit flies. Note: This method is not designed for humane release, as the soap will coat the flies.
Dripping Dish Soap Into Apple Cider Vinegar For DIY Fruit Fly Trap
Supplies needed:
- Small container, bowl, or dish
- Dish soap
- Apple cider vinegar (ACV)
Instructions:
Making this trap is incredibly easy:
- Pour apple cider vinegar into a container. Fill the bottom of a small container, bowl, or dish with apple cider vinegar. As with the other traps, the scent of ACV attracts the fruit flies.
- Add dish soap and mix. Add several drops of dish soap to the apple cider vinegar and gently mix to create a soapy solution. The dish soap breaks the surface tension of the vinegar. When fruit flies land on the mixture, they will become trapped and unable to fly away due to the soap.
This dish soap technique can also be combined with the plastic wrap or funnel traps for enhanced effectiveness. Simply add a few drops of dish soap to the apple cider vinegar before covering the container with plastic wrap or a funnel. This adds another trapping mechanism to your setup.
#4: The Rotting Fruit Trap: Using Natural Bait
We also experimented with traps that use what fruit flies love most: actual fruit! This method swaps out apple cider vinegar for the ultimate fruit fly attractant.
Supplies needed:
- Small glass jar, cup, or container
- Plastic wrap or paper funnel (depending on your chosen trap mechanism)
- A small piece of ripe or overripe fruit, such as a banana peel or apple slice
Instructions:
To create a rotting fruit trap, simply replace the apple cider vinegar in either the Plastic Wrap Trap or Funnel Trap with a piece of banana peel, apple slice, peach, or other ripe fruit. You can also add a fruit scrap in addition to apple cider vinegar for a super-enticing bait. Be sure to replace the fruit scrap every day or two to prevent unpleasant odors in your kitchen as it continues to decay.
Finding the Best Fruit Fly Trap: Our Experiment Results
As you can see in the photos, we set up four different DIY traps to compare their performance and determine the most effective method. The homemade traps we tested were variations combining different techniques and baits:
- Plastic Wrap Trap with banana peel
- Funnel Trap with ACV + banana peel
- Plastic Wrap Trap with ACV + dish soap
- Dish Soap Trap with ACV
4 DIY Fruit Fly Traps Close Up
Our experiment revealed that the type of bait was more crucial than the trap design. Traps using banana peel performed significantly better than those using only apple cider vinegar. The two Plastic Wrap Traps were almost identical in construction, but the one baited with banana peel dramatically outperformed the one with ACV and dish soap. Perhaps apple cider vinegar is less appealing when there’s real fruit nearby?
Based on our results, we suggest that no matter which trap you choose to set up, add a piece of fruit scrap to it! We slightly preferred the plastic wrap trap because it was easier to assemble and less prone to accidental spills. We did knock over the funnel trap once, releasing some trapped flies back into the kitchen – oops!
What Attracts Fruit Flies the Most? Banana Peel vs. Strawberry vs. Apple
Our initial experiment led to another intriguing question: which type of fruit is the most effective bait for fruit flies? We decided to conduct a follow-up test using three readily available fruits: a banana peel, apple slices, and a strawberry. We placed each fruit in a separate Plastic Wrap Trap, side-by-side on our kitchen counter, and observed the results over 24 hours.
While the banana peel started out strong (it was the ripest at the beginning), the fruit flies were ultimately most attracted to the strawberry. The banana peel still caught a good number of flies, but the strawberry became increasingly attractive as it ripened further, catching even more flies over time. Interestingly, the apple slices didn’t attract a single fruit fly!
Store-Bought Fruit Fly Traps: When DIY Isn’t Enough
If you’re not having success with DIY solutions, or if you prefer a more convenient option, there are commercially available fruit fly traps you can purchase. These store-bought traps often have thousands of positive reviews and generally cost less than $20. They might be worth considering if you want a trap that also catches other types of flying insects, or if you prefer a more discreet appearance compared to DIY traps.
Collage of Storebought Fruit Fly Traps
During our fruit fly experiments, we purchased a pack of Terro Fruit Fly Traps to compare their performance against our homemade traps. We placed a Terro trap next to our banana and strawberry traps for 24 hours to see which of the three performed best.
Again, our homemade strawberry trap proved to be the most effective, followed closely by the homemade banana peel trap. The store-bought trap caught only one fruit fly in the initial 24-hour period. HOWEVER…
Terro Fruit Fly Trap With Dead Fruit Flies Visible
To get a clearer picture, we removed our DIY traps and left the store-bought Terro trap in place for another 24 hours. That’s when it accumulated the impressive collection of fruit flies you see in the photo above. So, store-bought traps definitely work, but they may not be as immediately effective as homemade traps. Our conclusion? Use store-bought traps if you prefer a more subtle look, especially for ongoing prevention, but homemade traps are often the best way to quickly eliminate fruit flies right away!
How to Prevent Fruit Flies: Simple Tips to Keep Them Away
While getting rid of fruit flies is relatively straightforward, preventing them from infesting your home in the first place is the ideal scenario. Here are simple preventative measures you can take to minimize fruit fly attraction and breeding in your house:
- Clean kitchen surfaces regularly. Wipe down kitchen counters, stovetops, tables, and any surfaces that might collect food residue or spills. Fruit flies are strongly attracted to fruit, sugary liquids, and alcohol, so prompt cleanup is essential!
- Take out your trash frequently. Leaving food scraps in your garbage can, especially overnight, can quickly turn it into a fruit fly breeding ground. Empty trash cans regularly, especially kitchen trash.
- Dispose of overripe fruit promptly. Monitor your fruit bowl and refrigerator for browning or overly ripe fruits like apples and bananas. Get rid of them before they become an attractant and breeding site for fruit flies.
- Wash your fruit and vegetables as soon as you bring them home. You can eliminate any fruit fly eggs or larvae that might be present on produce from the grocery store by washing fruits and vegetables immediately upon bringing them home (except for berries, which can spoil faster if washed before storing).
- Store produce in the refrigerator whenever possible. Fruit flies don’t thrive in cold environments. When in doubt, store your fruits and vegetables in the refrigerator to deter them.
- Clean your sink drain regularly. Food particles and organic matter accumulating in your sink drain can attract fruit flies. Run your garbage disposal regularly, or flush your drains with hot water and a drain cleaner periodically to eliminate potential breeding sites.
Finally, if you spot fruit flies in your home, don’t panic! While you should take action quickly to prevent the problem from worsening, the DIY and store-bought solutions described in this article are easy to implement, effective, and fast-acting. You might even enjoy becoming a fruit fly scientist for a little while, just like we did!
