Got tiny buzzing pests invading your kitchen space? You might be dealing with fruit flies! Don’t worry, you’re not alone. These common nuisances are a frequent household problem, but thankfully, banishing fruit flies from your home doesn’t require breaking the bank or complicated solutions. In fact, the answer to your fruit fly woes might already be in your pantry! Recently, we faced a fruit fly invasion at home for the first time in years, prompting us to put various elimination methods to the test. Through careful experimentation and meticulous note-taking, we’ve discovered the most effective fruit fly traps and are excited to share our findings with you.
These homemade traps are incredibly easy to assemble using everyday, natural ingredients you likely already have. Think simple, DIY-friendly, and completely chemical-free solutions. For those who prefer a humane approach, we’ll also explore options to release the captured fruit flies outdoors. Beyond traps, we’ll equip you with essential tips to prevent future fruit fly infestations, ensuring a pest-free kitchen.
Understanding Fruit Flies: What Are They?
Fruit flies are small, winged insects that are strongly attracted to the sweet smells of ripe and fermenting fruits and vegetables – their name is quite descriptive! They are also drawn to sugary substances, including fermented drinks like beer, wine, and juice. You’ll often find them congregating around fruit bowls, garbage disposals, trash cans, and even kitchen drains. They are about the size of a grain of rice and resemble small, tan or brownish houseflies, often distinguished by their red eyes. Fruit flies are most prevalent during the warmer months of summer and late fall, coinciding with fruit harvesting seasons.

A fruit fly problem can start with just a few hitchhikers entering your home on fresh produce. However, female fruit flies are prolific breeders, capable of laying hundreds of eggs in their short lifespan. These eggs can hatch in as little as 12 hours, and the flies can reach adulthood within days. This rapid reproduction cycle means a small number of fruit flies can quickly escalate into a full-blown infestation. Therefore, prompt action is crucial to get rid of fruit flies swiftly.
Identifying Fruit Flies: Fruit Flies vs. Fungus Gnats vs. Drain Flies
Fruit flies are often mistaken for other small flying insects commonly found indoors, particularly fungus gnats and drain flies. While all are small and annoying, correctly identifying the pest is key to choosing the most effective elimination method. The easiest way to differentiate them is by observing where you typically spot them and what larger insect they most closely resemble.
- Fruit Flies: Resemble small flies and are typically found near fruit bowls, garbage cans, or any source of fermenting or decaying food.
- Drain Flies: Look like small, fuzzy moths and are usually seen near sinks, drains, and damp areas.
- Fungus Gnats: Resemble small mosquitos and are commonly found around houseplants, as they breed in moist potting soil.
If you’re unsure which pest you’re dealing with, trying one of the traps described below can act as a diagnostic tool. If it attracts the insects in your home, you’re likely dealing with fruit flies!
4 Simple DIY Fruit Fly Traps: Household Solutions
Getting rid of fruit flies doesn’t have to be a complicated or costly endeavor. You probably already have everything you need right at home, along with a little patience. Each effective fruit fly trap operates on the same basic principle: attract the fruit flies and then prevent their escape. We experimented with the following 4 DIY methods and found a clear winner in terms of effectiveness. Since each method utilizes common household items, trying multiple approaches won’t hurt. Think of it as a fun, mini-science experiment in your own kitchen! Here are the first 4 methods we tested:
- Funnel Trap
- Plastic Wrap Trap
- Dish Soap Trap
- Rotting Fruit Trap
We’ll delve into the specifics of each method below, including our verdict on their performance. Keep in mind that some traps work faster than others, and it may take several days for any of these techniques to completely eliminate your fruit fly problem.
#1: The Paper Funnel Fruit Fly Trap
This trap uses a paper funnel to guide fruit flies into a container. The narrow opening at the bottom of the funnel makes it easy for flies to enter but difficult for them to find their way back out.
DIY Fruit Fly Trap With Paper Funnel
Supplies you’ll need:
- A small, clear jar, cup, or container – ideally with a narrow opening
- A sheet of paper or cardstock
- Tape
- Scissors
- Apple cider vinegar (ACV)
Step-by-step instructions:
- Choose your container: Select a small, clear container like a repurposed food jar or a plastic bottle. A narrow opening is beneficial for this trap design.
- Add the attractant: Pour a small amount of apple cider vinegar, old beer, or wine into the bottom of your container. These liquids emit scents that are irresistible to fruit flies.
- Create the paper funnel: Roll a piece of paper or cardstock into a cone shape, ensuring a very small opening at the pointed tip. Secure the cone shape with tape. You can also create the small opening by cutting the tip of the cone after taping. The opening should be roughly the size of a grain of rice.
- Assemble the trap: Place the paper funnel into the opening of your container, with the narrow tip pointing downwards into the container. You may need to adjust the funnel’s shape to ensure it sits securely on the container’s rim without touching the liquid attractant. Ensure there are no gaps around the funnel’s edge where flies could escape.
- Humane release (optional): To release captured fruit flies outdoors, carefully transport the entire trap outside, keeping the funnel in place to prevent escapes. Once outside, remove the funnel to allow the flies to fly away.
While store-bought funnels could be used, the opening at the bottom is often too wide, increasing the chances of fruit flies escaping. Homemade paper funnels offer more control over the opening size.
#2: The Plastic Wrap Fruit Fly Trap
Similar to the funnel trap, this method uses the alluring scent of apple cider vinegar to attract fruit flies. Plastic wrap tightly covers the container opening, with small holes that allow flies to enter but hinder their exit.
Supplies you’ll need:
- Small, clear jar, cup, or container
- Rubber band
- Plastic wrap or a plastic bag
- Toothpick
- Apple cider vinegar (ACV)
Step-by-step instructions:
- Select your container: Choose a small, clear jar, cup, or any glass container. The size isn’t critical, and clarity helps you monitor the trap’s effectiveness. Even an old can will work.
- Add the attractant: Pour apple cider vinegar into the container. Its strong scent is highly attractive to fruit flies. Old beer or wine can also be used, but avoid regular white vinegar, as it’s less effective.
- Cover with plastic wrap: Tightly stretch plastic wrap over the container opening and secure it firmly with a rubber band. Saran wrap works well, or you can repurpose a piece of a plastic bag.
- Poke small entry holes: Use a toothpick to carefully poke a few small holes in the plastic wrap. These holes should be just large enough for a fruit fly to pass through. A few holes are sufficient.
- Humane release (optional): To release captured flies, carefully take the trap outside without removing the plastic wrap. Once outdoors, remove the plastic wrap to let the flies escape.
Alternatively, you can adapt this trap using a metal lid from a jar. Puncture a small hole in the lid using a hammer and nail, creating an entry point for the flies.
#3: The Dish Soap Fruit Fly Trap
This trap simplifies the design by eliminating the need for a cover. Instead, it uses the surface tension of soapy water to trap fruit flies. Note: Fruit flies trapped in this method will not be able to be released humanely due to the soap.
Dripping Dish Soap Into Apple Cider Vinegar For DIY Fruit Fly Trap
Supplies you’ll need:
- Small container, bowl, or dish
- Dish soap
- Apple cider vinegar (ACV)
Step-by-step instructions:
- Pour apple cider vinegar: Fill the bottom of a small container, bowl, or dish with apple cider vinegar. The scent acts as the primary attractant.
- Add dish soap: Squirt several drops of dish soap into the apple cider vinegar and gently mix. The soap reduces the surface tension of the liquid. Fruit flies will be attracted to the vinegar, land on the surface, and become trapped by the soapy mixture, making it difficult for them to fly away.
For enhanced effectiveness, you can combine this dish soap method with the plastic wrap or funnel traps. Simply add a few drops of dish soap to the apple cider vinegar before covering the container. This provides an additional trapping mechanism.
#4: The Rotting Fruit Fruit Fly Trap
This variation substitutes apple cider vinegar with the fruit flies’ ultimate temptation: actual rotting fruit!
Supplies you’ll need:
- Small glass jar, cup, or container
- Plastic wrap or paper funnel (depending on your preferred trap style)
- A small piece of fruit scrap, such as a banana peel or apple slice
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 overripe banana peel, apple slice, or peach. You can also enhance the attractant by adding a fruit scrap to apple cider vinegar. However, be mindful that fruit scraps may need to be replaced every day or two to prevent unpleasant odors in your kitchen.
Determining the Best Fruit Fly Trap: Our Experiment Results
As shown in the photos, we set up 4 different DIY traps to compare their effectiveness side-by-side. The homemade traps we tested were:
- Plastic Wrap Trap with banana peel
- Funnel Trap with ACV + banana peel
- Plastic Wrap Trap with ACV + soap
- Dish Soap Trap with ACV
4 DIY Fruit Fly Traps Close Up
Our results indicated that the type of attractant was a more significant factor than the trap design itself. Traps baited with banana peel consistently outperformed those using only apple cider vinegar. The two Plastic Wrap Traps were nearly identical in construction, yet the banana peel trap captured significantly more fruit flies than the ACV + soap trap. It seems that while apple cider vinegar is attractive, the lure of real fruit is even more potent.
Therefore, our recommendation is to incorporate a fruit scrap into any DIY fruit fly trap you choose to set up! We slightly preferred the plastic wrap trap for its ease of construction and stability. We experienced a minor mishap with the funnel trap when it was accidentally knocked over, releasing some captured flies back into the kitchen – oops!
What Attracts Fruit Flies the Most? Fruit Bait Experiment
Driven by the success of fruit scraps in our initial trap tests, we decided to further investigate which type of fruit bait is most effective. We tested three readily available fruits: banana peel, apple slices, and a strawberry. Each fruit was placed in a Plastic Wrap Trap and positioned side-by-side on our kitchen counter for a 24-hour period.
While the banana peel initially appeared promising (it was the ripest at the start), the results revealed that fruit flies were most strongly attracted to the strawberry. The banana peel still captured a good number of flies, but the strawberry’s appeal increased as it became more overripe, attracting even more flies over time. Interestingly, the apple slices failed to attract any fruit flies at all!
Store-Bought Fruit Fly Traps: Convenient Alternatives
If DIY solutions aren’t working for you, or if you prefer a ready-made option, numerous effective store-bought fruit fly traps are available. These traps generally receive thousands of positive reviews and are typically priced under $20. They might be a worthwhile consideration if you’re dealing with multiple types of flying insects or prefer a more discreet trap design compared to homemade versions.
Collage of Storebought Fruit Fly Traps
During our fruit fly experiment, we purchased a pack of Terro Fruit Fly Traps to compare their performance against our homemade traps. We placed a Terro trap alongside our banana and strawberry traps for 24 hours to see which performed best.
Again, our homemade strawberry trap proved most effective, closely followed by the banana peel trap. The store-bought trap only captured a single fruit fly during this initial 24-hour period. HOWEVER…

To ensure a fair assessment, we discarded our DIY traps and left the store-bought Terro trap in place for another 24 hours. Over this extended period, the Terro trap successfully captured a significant number of fruit flies, as shown in the image above. So, while store-bought traps are effective, they may not be as immediately fast-acting as homemade traps. Our conclusion? Store-bought traps are a good option if you prioritize a discreet appearance, particularly for long-term placement. However, for rapid fruit fly elimination, homemade traps are remarkably effective and often the best solution for immediate results!
Preventing Fruit Flies: Proactive Measures
While eliminating fruit flies is relatively straightforward, preventing them from infesting your home in the first place is the ideal approach. Here are simple preventative measures you can take:
- Maintain clean kitchen surfaces: Regularly wipe down kitchen counters, stovetops, tables, and any surfaces prone to collecting food residue or spills. Fruit flies are particularly drawn to fruit, sugary juices, and alcohol, so promptly cleaning up spills is essential.
- Dispose of trash promptly: Food scraps left in your garbage can overnight can quickly become a breeding ground for fruit flies. Take out your trash regularly to minimize attractants.
- Manage overripe fruit: Regularly check your fruit bowl for overripe or decaying fruits like apples and bananas. Dispose of them before they become a fruit fly magnet.
- Wash produce immediately: Washing fruits and vegetables as soon as you bring them home from the store can eliminate any fruit fly eggs or larvae that may be present (except for berries, as washing them prematurely can accelerate spoilage).
- Refrigerate produce when possible: Fruit flies struggle to thrive in cold temperatures. When feasible, store fruits and vegetables in the refrigerator to deter infestations.
- Clean sink drains regularly: Food particles accumulating in your sink drain can attract fruit flies. Regularly run your garbage disposal or flush drains with hot water and vinegar to eliminate food debris.
Finally, remember not to panic if you spot fruit flies in your home. While swift action is advisable to prevent the problem from escalating, the solutions outlined in this guide are easy, effective, and fast-acting. You might even find yourself enjoying the process of becoming a fruit fly scientist, just as we did!
