How to Eliminate Small Flies in Kitchen: Your Ultimate Guide

Are tiny flies buzzing around your kitchen driving you crazy? You’re likely dealing with fruit flies, a common household nuisance. The good news is that getting rid of these pests doesn’t require harsh chemicals or professional help. You can effectively tackle a fruit fly problem using simple, do-it-yourself methods with items you probably already have at home. Like many homeowners, we recently experienced a fruit fly invasion in our kitchen, despite years of being pest-free. This prompted us to test and document 7 different fruit fly elimination techniques. We meticulously noted our findings and are excited to share the most effective homemade fruit fly traps and prevention strategies with you.

These DIY traps are not only easy to create but also rely on natural, readily available ingredients. If you’re environmentally conscious, you’ll be pleased to know that some of these methods even allow you to release the captured flies outdoors, unharmed. Beyond traps, we’ll also equip you with essential tips to prevent future fruit fly infestations, keeping your kitchen pest-free for good.

Understanding the Fruit Fly

Fruit flies are small, winged insects that are strongly attracted to ripe and fermenting fruits and vegetables, hence their name. They are also drawn to sugary substances and fermented drinks like beer, wine, and juice. You’ll often find them congregating around fruit bowls, garbage disposals, trash cans, and even sink drains. They are diminutive in size, about as small as a grain of rice, and have a tan or brownish color, resembling tiny houseflies with distinctive red eyes. Fruit flies are most prevalent during warmer months, particularly summer and late fall, when fruits are abundant.

A fruit fly infestation often begins 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, with eggs hatching in as little as 12 hours. These flies can mature into adults in just a few days, meaning a small initial presence can quickly escalate into a large, bothersome swarm. This rapid reproduction cycle underscores the importance of prompt action to eliminate fruit flies as soon as you notice them.

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, particularly fungus gnats and drain flies. While all are small and winged, accurate identification is key to choosing the most effective elimination method. The easiest way to distinguish them is by observing where you typically see them and their resemblance to other insects.

• Fruit Flies: Resemble tiny flies and are found near fruit bowls, decaying food, garbage, and spills of sugary drinks.
• Drain Flies: Look like small, fuzzy moths and are usually spotted near sinks, drains, and damp areas.
• Fungus Gnats: Resemble small mosquitoes and are typically found around houseplants, as they breed in moist potting soil.

If you are uncertain about the type of fly you’re dealing with, try setting up one of the traps described below. If it successfully attracts the pests, you’ve likely confirmed the presence of fruit flies.

4 Simple DIY Fruit Fly Traps

Eradicating fruit flies is neither complicated nor expensive. You likely already have everything you need in your kitchen cabinets. The principle behind each of these traps is simple: lure the fruit flies in and prevent their escape. We personally tested the following 4 DIY methods and identified a clear winner based on effectiveness. Since each method utilizes common household items, trying multiple traps is easy and worthwhile. Think of it as a fun, mini-science experiment in your kitchen! Here are the first 4 methods we put to the test:

1. Funnel Trap
2. Plastic Wrap Trap
3. Dish Soap Trap
4. Rotting Fruit Trap

Let’s delve into the specifics of each method, and we’ll reveal our top pick later on. Keep in mind that some traps work faster than others, and complete eradication may take several days, regardless of the technique used.

#1: The Paper Funnel Fruit Fly Trap

This trap design uses a paper funnel to guide fruit flies into a container. The narrow opening at the funnel’s bottom makes it easy for flies to enter but difficult to exit.

DIY Fruit Fly Trap With Paper Funnel

Supplies you’ll need:

• A small, clear jar, cup, or container – a narrow opening is preferable.
• A sheet of paper or cardstock.
• Tape.
• Scissors.
• Apple cider vinegar (ACV).

Instructions:

1. Select a Container: Choose a small, clear container like a repurposed food jar or a plastic bottle. A narrow opening will enhance the trap’s effectiveness.
2. Add Apple Cider Vinegar: Pour a small amount of apple cider vinegar, old beer, or wine into the container’s bottom. These liquids act as potent attractants for fruit flies.
3. Create the Funnel: Shape a piece of paper or cardstock into a cone with a very small opening at the tip. Secure the cone shape with tape. You can trim the tip to create the small opening if needed. The opening should be approximately the size of a grain of rice.
4. Assemble the Trap: Place the paper cone into the container’s opening. Adjust the funnel so it rests securely on the rim without touching the liquid. Ensure there are no gaps around the funnel’s edge through which flies could escape.
5. Humane Disposal (Optional): To release trapped flies outdoors, carefully carry the entire trap outside without disturbing the funnel. Once outside, remove the funnel to allow the flies to escape.

While you can use a store-bought funnel, the opening may be too wide, potentially allowing captured fruit flies to escape. A homemade paper funnel offers a more precisely sized opening.

#2: The Plastic Wrap Fruit Fly Trap

Similar to the funnel trap, this method uses the enticing scent of apple cider vinegar to lure fruit flies into a container covered with plastic wrap. Small holes poked in the plastic allow entry but hinder exit.

Supplies you’ll need:

• A small, clear jar, cup, or container.
• A rubber band.
• Plastic wrap or a plastic bag.
• A toothpick.
• Apple cider vinegar (ACV).

Instructions:

1. Choose Your Container: Select a small, clear jar, cup, or glass container. Clarity helps monitor the trap’s success, but even a can will work.
2. Add the Lure: Pour apple cider vinegar into the container. Its sweet, fermented scent is irresistible to fruit flies. Old beer or wine can also be used, but avoid white vinegar, which is not as attractive.
3. Cover with Plastic Wrap: Tightly stretch plastic wrap over the container’s opening and secure it with a rubber band. You can also use a piece cut from a plastic bag.
4. Poke Entry Holes: Use a toothpick to poke a few small holes in the plastic wrap. The holes need to be large enough for flies to enter but small enough to discourage escape.
5. Humane Release (Optional): To release the trapped flies, carefully take the trap outdoors, ensuring the plastic wrap remains secure. Remove the plastic wrap outside to free the flies.

Alternatively, you can create this trap using a jar with a metal lid. Simply puncture a small hole in the lid using a hammer and nail instead of using plastic wrap. Mason jars or old food jars work well for this variation.

#3: The Dish Soap Fruit Fly Trap

This trap deviates from the previous two by eliminating the need for a cover. Instead, it utilizes the surface tension-breaking properties of dish soap to trap fruit flies. Note: This method is not designed for humane release, as the soap will coat and incapacitate the flies.

Dripping Dish Soap Into Apple Cider Vinegar For DIY Fruit Fly Trap

Supplies you’ll need:

• A small container, bowl, or dish.
• Dish soap.
• Apple cider vinegar (ACV).

Instructions:

• Pour Apple Cider Vinegar: Fill the bottom of your chosen container with apple cider vinegar. The scent will attract the fruit flies.
• Add Dish Soap: Add several drops of dish soap to the apple cider vinegar and gently mix. The soap reduces the surface tension of the vinegar, causing flies that land on the surface to sink and become trapped.

This dish soap method can also be enhanced by combining it with the plastic wrap or funnel trap. Adding dish soap to the apple cider vinegar before covering the container provides an additional trapping mechanism.

#4: The Rotting Fruit Fruit Fly Trap

This variation replaces apple cider vinegar with an even more irresistible lure for fruit flies: actual rotting fruit.

Supplies you’ll need:

• A small glass jar, cup, or container.
• Plastic wrap or paper funnel (depending on your preferred trap style).
• A small piece of overripe fruit, such as a banana peel or apple slice.

Instructions:

To create a rotting fruit trap, simply substitute apple cider vinegar with a piece of banana peel, apple slice, or peach in either the Plastic Wrap Trap or Funnel Trap setup. You can also enhance the attractant by adding a fruit scrap to your apple cider vinegar. However, be prepared to replace the fruit every day or two to prevent unpleasant odors in your kitchen.

Determining the Best Fruit Fly Trap

To rigorously test effectiveness, we set up all four DIY traps side-by-side. Our test included:

1. Plastic Wrap Trap with banana peel.
2. Funnel Trap with ACV and banana peel.
3. Plastic Wrap Trap with ACV and dish soap.
4. Dish Soap Trap with ACV.

4 DIY Fruit Fly Traps Close Up

Our results indicated that the lure was more critical than the trap type. Traps baited with banana peel significantly outperformed those using apple cider vinegar alone. While both plastic wrap traps were similarly constructed, the banana peel trap captured dramatically more flies than the ACV and soap trap. Perhaps apple cider vinegar is less appealing when real fruit is present?

Therefore, our primary recommendation is to include a piece of fruit in any DIY fruit fly trap you create. We slightly preferred the plastic wrap trap due to its ease of construction and stability. We accidentally knocked over the funnel trap once, releasing captured flies back into the kitchen – an unwanted setback!

What Attracts Fruit Flies the Most?

Intrigued by the success of fruit lures, we conducted a follow-up experiment to identify the most attractive fruit bait. We tested three readily available fruits: banana peel, apple slices, and strawberry. Each fruit was placed in a separate Plastic Wrap Trap and positioned side-by-side on our counter for 24 hours.

While the banana peel initially seemed promising (it was the most ripe at the start), strawberries ultimately proved to be the most effective fruit fly attractant. The banana peel still captured a good number of flies, but the strawberry’s appeal increased as it ripened further. Interestingly, the apple slices didn’t attract a single fruit fly!

Store-Bought Fruit Fly Traps

If DIY methods prove unsuccessful or you prefer a ready-made solution, numerous commercial fruit fly traps are available. These traps generally receive excellent customer reviews and are typically priced under $20. Store-bought traps might be a worthwhile option if you’re dealing with various types of flying insects or desire a more discreet trap design.

Collage of Storebought Fruit Fly Traps

During our testing, we purchased 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.

Again, our homemade strawberry trap was the most effective, closely followed by the banana peel trap. The store-bought trap initially caught only one fly. HOWEVER…

To ensure a fair assessment, we discarded our DIY traps and left the Terro trap in place for another 24 hours. Over this extended period, the Terro trap captured a significant number of fruit flies, as shown above. So, store-bought traps are effective, but they may not be as fast-acting or potent as homemade traps, especially those baited with strawberry or banana. Consider store-bought traps if you prioritize discreetness, particularly for long-term placement, but for rapid fruit fly elimination, homemade traps are a superior choice.

Preventing Fruit Flies: Proactive Measures

While eliminating fruit flies is relatively straightforward, preventing infestations is the ideal approach. Here are simple preventative measures to keep fruit flies from establishing themselves in your kitchen:

1. Maintain Clean Kitchen Surfaces: Regularly wipe down countertops, stovetops, tables, and all surfaces prone to food residue or spills. Fruit flies are especially drawn to fruit, sugary liquids, and alcohol, so promptly clean up any spills.
2. Regularly Empty Trash: Food scraps left in your garbage can quickly become breeding grounds for fruit flies, especially in warmer weather. Empty your trash daily to remove potential attractants.
3. Promptly Dispose of Overripe Fruit: Monitor your fruit bowl for signs of overripeness or rot in fruits like apples and bananas. Dispose of them before they attract fruit flies and become breeding sites.
4. Wash Produce Immediately Upon Arrival: 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 on the surface (except for berries, which are best washed just before consumption to prevent premature spoilage).
5. Refrigerate Produce When Possible: Fruit flies thrive in warmer temperatures and are less active in the cold. Storing fruits and vegetables in the refrigerator whenever feasible will deter fruit fly infestations.
6. Clean Sink Drains Regularly: Food particles accumulating in sink drains can also attract fruit flies. Regularly run your garbage disposal and flush drains with hot water or a drain cleaner to eliminate food debris.

Finally, remember that discovering fruit flies in your kitchen is not a cause for panic. While swift action is advisable to prevent a full-blown infestation, the solutions outlined here are simple, effective, and fast-acting. You might even find yourself enjoying the process of becoming a kitchen entomologist, just like we did!
