Homemade Fruit Fly Trap

I hate fruit flies. They are such pests! They have to be one of the most annoying insects because they multiply and can be hard to eradicate.

When a bout of these pesky bugs pop up, I immediately make a fruit fly trap, and within a few hours, they are all gone. I’m sharing my go-to trap in case you also need quick, easy, and natural pest control.

Ingredients

  • 16-ounce jar – I used a pint-size mason jar with a regular mouth opening, but any similarly sized jar will work like a clean empty jam, spaghetti sauce, or pickle jar.
  • 1 cup apple cider vinegar – you can also use fruit juice, honey water, or make a mixture of yeast, sugar & water.
  • 3 drops liquid dish soap – any brand or scent
  • 8.5 x 11-inch piece of paper I used white copy paper, but any type of paper that is similar in size will work. If you have a funnel with a wider tip, that may work as well. 
  • tape or a stapler to secure the cone shape of the paper

How to Make a Fruit Fly Trap

  1. CONE. Create a cone with 1 piece of 8.5×11 paper, making it smaller at the base and wider up top.
    • Make sure it’s wide enough that the paper sits about halfway in the (16-ounce) mason jar. Tape the paper so it stays in a cone shape.
  2. MIXTURE. Remove the cone from the jar and add about 1 cup of apple cider vinegar. Squeeze about 3 drops of dish soap into the jar and stir to mix.
    • Microwave the jar for about 20-30 seconds. This will make the smell of the mixture more potent, drawing the flies in more quickly.
  3. ASSEMBLE. Add the cone and place it in a spot where the fruit flies have been.

Alternative Method

The paper cone method is my favorite and I have great results. I have also seen people successfully poke holes in the lid of the jar and screw the lid on. Another idea is to secure a piece of plastic wrap on the top of the jar with a rubber band, then poke a few tiny holes in it.

DIY Fruit Fly Trap {Gnat Trap}

By: Lil’ Luna
This DIY fruit fly trap literally takes 2 minutes to put together and works AWESOME! Say goodbye to fruit flies!
Servings: 1 trap

  • tape

Instructions 

  • Create a cone with 1 piece of 8.5×11 paper, making it smaller at the base and wider up top.
  • Make sure it's wide enough that the paper sits about halfway in the (16-ounce) mason jar. Tape the paper so it stays in a cone shape.
  • Remove the cone from the jar and add about 1 cup of apple cider vinegar. Squeeze about 3 drops of dish soap into the jar and stir to mix.

Notes

To clean out the jar after you’ve caught fruit flies:

  • Take the jar outside before removing the cone, that way any insects that may still be able to fly won’t escape back into your house.
  • I usually pour the contents into the rocks I have outside and then spray it with the hose. You can also pour the contents down the drain.
  • Either way, rinse the empty jar with hot soapy water.

FAQs

  • The apple cider vinegar attracts the fruit flies towards the scent and the dish soap’s purpose is to break the surface tension of the vinegar so the flies can’t sit on top of the liquid.
  • The inverted cone made out of paper is what traps them because the wide top and small bottom make it easy for the flies to enter the jar, and harder for them to get back out once they’re in!
  • Since they can’t get out, and they can’t sit on the surface of the liquid, it’s only a matter of time before they meet their end. (Unfortunate for them, but a victory for us and our fruit!)
  • Throw out overripe or rotting fruit in the trash, or compost it.
  • Take out the garbage regularly.
  • Keep your sink and garbage disposal clear.
  • Store ripe fruits and vegetables in the fridge instead of a fruit bowl.
  • Fruit flies don’t like fresh basil so keep a fresh basil plant in the kitchen or place fresh basil leaves around the fruit basket. 
  • Plants that can be kept in your kitchen that repel flies, fungus gnats, and even mosquitoes are rosemary, mint, sage, catnip, and lavender.
  • There is a way to catch and release. Instead of using vinegar and a bit of dish soap, place overripe fruit in the jar and top with the paper cone. A few flies may be able to find their way back through the cone, but most will stay in the jar. You can then release them outside.
  • If the flies are attracted to the trap but aren’t getting stuck inside, try adjusting the size of the cone. If the tip is too small they may not go all the way down inside. If the tip is too large, they can more easily escape.

    It took me a few tries to get the paper cone the right shape for it to hold in place with a hole just the right size. The content inside certainly did attract them.

    I just wanted to say thank you for sharing this! We had been going crazy with Fruit flies for weeks. I put the jar out yesterday morning and by the evening there were about 50 in there. So gross but so satisfying 🙂 I cleaned it out this morning and replaced the liquid and have caught a few stragglers. Our kitchen feels so much nicer and my husband is amazed at the results. Thank you so much!!!

    1. Kristyn Merkley says:

      You are so welcome!! Those are annoying little things! I am glad it helped!

    Omg this worked!!! I’ve tried using other methods but this caught like fifty flies in one day. I didn’t even know I had that many in my home yuck! Instead of apple cider vinegar I used kombucha with dish soap and it worked so well. I’m so impressed, thanks so much for sharing!!!

    1. Kristyn Merkley says:

      Thanks for sharing that! I haven’t tried using that..I will need to! I am glad it worked!

    it caught a fruit fly before i could even put the cone on it.

    1. Kristyn Merkley says:

      Yay!! Glad it worked before you could even finish 🙂

    This worked very well for me. I did exactly as you said and even 24 hours later the fruit flies are still piling up. I think using the paper cone and microwaving for aroma were key, because when I just had ACV/dish soap in bowls it wasn’t nearly as effective. Thank you for the tip!

    1. Kristyn Merkley says:

      You are so welcome!! I am happy it worked 🙂

    The paper cone worked a little bit. but mostly the little buggers just sat on the outside of the paper cone. I switch the top to plastic and poked holes in with a toothpick and that did the trick …they are all out of my kitchen within an hour.

    1. Kristyn Merkley says:

      I’m glad you found a way to get them! 🙂 Thanks for sharing!
