Are tiny bugs buzzing around your fruit bowl or hovering near your kitchen sink? You might be dealing with fruit flies! Don’t worry, these common household pests are more of a nuisance than a serious problem, and thankfully, getting rid of fruit flies is easier than you think. You probably already have everything you need right in your kitchen to make effective fruit fly traps. After experiencing a recent fruit fly invasion myself, I decided to put various methods to the test. The results are in, and I’m excited to share the best homemade fruit fly traps and simple ways to prevent them from coming back.
These DIY traps are incredibly easy to assemble using common household items and natural ingredients. They’re also a chemical-free way to manage these pests. If you’re feeling compassionate, some of these methods even allow you to release the captured fruit flies outdoors. Let’s dive into understanding fruit flies and how to banish them from your home.
What Exactly Are Fruit Flies?
Fruit flies are small, winged insects that are strongly attracted to ripe and fermenting fruits and vegetables – their name is quite descriptive! They are also drawn to sugary substances like spilled juice, beer, wine, and even damp drains. You’ll often find them congregating around fruit bowls, garbage disposals, trash cans, and pantries. They are tiny, about the size of a grain of rice, and typically tan or brownish in color with distinctive red eyes. Fruit flies are most prevalent during warmer months, particularly summer and late fall when fruits are abundant.
A fruit fly problem can start with just a few flies hitchhiking into your home on fruits or vegetables from the grocery store or garden. 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 larvae can develop into adult flies in just a few days. This rapid life cycle explains why a small number of fruit flies can quickly escalate into a full-blown infestation. Prompt action is key to getting rid of fruit flies before they multiply.
Identifying Fruit Flies: Fruit Flies vs. Fungus Gnats vs. Drain Flies
It’s easy to mistake fruit flies for other small flying insects commonly found indoors, especially fungus gnats and drain flies. While all are small and annoying, correctly identifying the pest is important for choosing the most effective removal method. The easiest way to tell them apart is by observing where you see them and what they resemble.
- Fruit flies: Resemble small flies and are typically found near fruit bowls, overripe produce, garbage, and other food sources.
- Drain flies: Look like small, fuzzy moths and are usually seen around sinks, drains, and damp areas.
- Fungus gnats: Resemble small mosquitoes and are often found near houseplants, as they thrive in moist potting soil.
If you are uncertain which pest you’re dealing with, try one of the DIY traps described below. If it attracts the insects in your home, you likely have fruit flies!
4 Simple DIY Fruit Fly Trap Recipes
Eliminating fruit flies doesn’t require special equipment or expensive pesticides. All you need are a few common household items and a bit of patience. The basic principle behind each trap is to lure the fruit flies in and prevent their escape. I tested these 4 DIY methods and found a clear winner. Because each method uses ingredients you probably already have, it’s worth trying more than one to see what works best for you. Consider it a fun science experiment in your kitchen! Here are the first 4 methods I tested:
- Funnel Trap
- Plastic Wrap Trap
- Dish Soap Trap
- Rotting Fruit Trap
Some traps work faster than others, and it may take a few days to completely eliminate your fruit fly problem, regardless of the method you choose.
#1: The Paper Funnel Fruit Fly Trap
This trap uses a paper funnel to guide fruit flies into a container filled with an attractant. The narrow opening of the funnel makes it easy for them to enter but difficult to exit.
Supplies needed:
- Small, clear jar, cup, or container 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 mason jar, a drinking glass, or a plastic bottle. A narrow opening is ideal for this trap.
- Add the attractant: Pour a small amount of apple cider vinegar, old beer, or wine into the bottom of the container. The sweet, fermented scent will attract fruit flies.
- Create the funnel: Roll a piece of paper or cardstock into a cone shape with a very small opening at the pointed end. Secure the cone shape with tape. You can trim the tip to create a small opening, about the size of a grain of rice.
- Position the funnel: Place the paper funnel into the opening of your container, with the narrow opening pointing down towards the liquid. Adjust the funnel so it sits securely on the rim of the container without touching the liquid. Ensure there are no gaps around the edges where flies could escape.
- Optional humane release: To release the trapped fruit flies outdoors, carefully carry the entire trap outside without disturbing the funnel. Remove the funnel and allow the flies to fly away.
While you could use a store-bought funnel, the opening may be too wide, allowing captured fruit flies to escape. A homemade paper funnel allows for a more precisely sized opening.
#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 into a container covered with plastic wrap. Small holes poked in the plastic allow entry but make escape challenging.
Supplies needed:
- Small, clear jar, cup, or container
- Rubber band
- Plastic wrap or a plastic bag
- Toothpick
- Apple cider vinegar (ACV)
Instructions:
- Choose your container: Select a small, clear container. Clarity helps you monitor your trap’s success, but any container will work.
- Add the attractant: Pour apple cider vinegar into the container. Again, old beer or wine can be substituted, but avoid using regular white vinegar as it’s not as effective.
- Cover with plastic wrap: Stretch plastic wrap tightly over the opening of the container and secure it with a rubber band to create an airtight seal. You can also use a piece of a plastic bag.
- Poke small holes: Use a toothpick to carefully poke several small holes in the plastic wrap. These holes should be just large enough for fruit flies to enter.
- Optional humane release: To release the trapped fruit flies, carefully take the trap outside, remove the plastic wrap, and let them fly away.
Alternatively, you can create a similar trap using a metal lid. Use a hammer and nail to puncture a small hole in the lid of a mason jar or old food jar.
#3: The Dish Soap Fruit Fly Trap
This trap is even simpler than the previous two, as it doesn’t require any cover. It relies on the principle that dish soap reduces the surface tension of the liquid, trapping fruit flies that land on it. Note: Fruit flies trapped with this method will not be able to be released outdoors.
Supplies needed:
- Small container, bowl, or dish
- Dish soap
- Apple cider vinegar (ACV)
Instructions:
- Pour in apple cider vinegar: Fill the bottom of a small container, bowl, or dish with apple cider vinegar. The scent will attract fruit flies.
- Add dish soap: Add a few drops of dish soap to the apple cider vinegar and gently mix. The soap breaks the surface tension of the vinegar. Fruit flies will be attracted to the scent, land on the surface, and become trapped in the soapy solution.
You can also enhance the funnel or plastic wrap traps by adding dish soap to the apple cider vinegar before covering the container. This adds an extra trapping mechanism.
#4: The Rotting Fruit Fruit Fly Trap
Fruit flies are naturally drawn to overripe fruit, so using actual fruit as bait can be highly effective.
Supplies needed:
- Small glass jar, cup, or container
- Plastic wrap or paper funnel (depending on your chosen trap style)
- A small piece of overripe fruit, such as a banana peel or apple slice
Instructions:
To make 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, or peach. You can also combine fruit scraps with apple cider vinegar to enhance the lure. Remember to replace the fruit every day or two to prevent unpleasant odors in your kitchen.
Finding the Best Fruit Fly Trap: Experiment Results
To determine the most effective DIY trap, I tested four different combinations:
- Plastic Wrap Trap with banana peel
- Funnel Trap with ACV + banana peel
- Plastic Wrap Trap with ACV + soap
- Dish Soap Trap with ACV
The results showed that the lure was more critical than the trap design. Traps using banana peel performed significantly better than those with apple cider vinegar alone. The Plastic Wrap Trap with banana peel and the Funnel Trap with ACV + banana peel were the most successful. It seems that while apple cider vinegar is attractive, real fruit is even more irresistible to fruit flies.
Therefore, regardless of the trap style you choose, adding a piece of fruit can significantly improve its effectiveness. I slightly preferred the plastic wrap trap for its ease of assembly and stability. I accidentally knocked over the funnel trap once, releasing some trapped flies back into the kitchen – oops!
What Lures Fruit Flies Best? Fruit Bait Experiment
Intrigued by the success of fruit scraps, I conducted a further experiment to determine the most attractive type of fruit bait. I tested three readily available fruits: banana peel, apple slices, and a strawberry, each placed in a Plastic Wrap Trap for 24 hours.
While the banana peel initially seemed promising (being the most ripe at the start), the strawberry ultimately attracted the most fruit flies. The banana peel still caught a good number, but as the strawberry became more fermented, it became increasingly appealing. Surprisingly, the apple slices didn’t attract any fruit flies in this test!
Store-Bought Fruit Fly Trap Options
If DIY traps aren’t working for you, or if you prefer a ready-made solution, there are commercially available fruit fly traps. These traps often receive excellent reviews and are typically priced under $20. They might be a good option if you want a trap that also catches other types of flying insects or if you prefer a more discreet appearance.
During my experiments, I purchased a pack of Terro Fruit Fly Traps to compare their performance to my homemade traps. I placed a Terro trap alongside banana and strawberry traps for 24 hours.
Again, the homemade strawberry trap performed best, followed closely by the banana peel trap. The store-bought trap only caught a single fruit fly in the initial 24-hour period. HOWEVER…
To be thorough, I removed the DIY traps and left the store-bought trap out for another 24 hours. Over the extended time, the Terro trap did effectively catch a significant number of fruit flies. So, store-bought traps do work, just not as quickly or aggressively as the best homemade traps in my experience.
My verdict? Store-bought traps are a good choice if you want a more subtle trap, especially for long-term placement. But for fast and effective fruit fly removal, homemade traps, particularly those baited with fruit like strawberries or banana peels, are hard to beat!
Preventing Fruit Flies: Stop Infestations Before They Start
While getting rid of fruit flies is relatively simple, preventing them from infesting your home in the first place is even better. Here are some straightforward preventative measures:
- Keep kitchen surfaces clean: Regularly wipe down countertops, stovetops, tables, and any surfaces prone to food residue or spills. Fruit flies are especially attracted to fruit, sugary liquids, and alcohol, so clean up spills promptly!
- Take out the trash frequently: Food scraps left in your garbage can become a breeding ground for fruit flies, especially in warm weather. Empty your trash cans regularly, ideally daily.
- Dispose of overripe fruit promptly: Monitor your fruit bowl and discard any browning or rotting fruits before they attract fruit flies and become a breeding site.
- Wash produce immediately after bringing it home: Washing fruits and vegetables as soon as you get them home from the store can remove any fruit fly eggs or larvae that may be present (except for berries, which can spoil faster if washed before storage).
- Refrigerate produce when possible: Fruit flies don’t thrive in cold environments. Store fruits and vegetables in the refrigerator whenever possible to deter them.
- Clean your sink drain regularly: Food particles trapped in your sink drain can also attract fruit flies. Run your garbage disposal regularly and flush drains with hot water or a drain cleaner periodically.
Finally, remember that spotting fruit flies isn’t a sign of a dirty home; they are simply attracted to food sources. Take swift action using the easy and effective methods described here, and you can quickly regain control of your kitchen and say goodbye to these pesky fruit flies! You might even enjoy a little bit of fruit fly science along the way.
