Published on February 24th 2016 by under DIY

Many dread summer time due to pesky fruit fly infestation. Not only indoor areas, but gardens can also get affected by them. Homemade fruit fly traps offer an easy solution in this regard. Here are a handful of tutorials to guide you on how to make them.

1. DIY Funnel Fruit Fly Trap with Apple Cider Vinegar

Things Needed

  • ½ cup Apple cider vinegar
  • Two drops of dish wash soap
  • A piece of ripe or overripe fruit (optional)

Instructions

  1. Heat the vinegar and pour it into a mason jar. You can also cut off the upper third of a two-liter plastic soda bottle, pop bottle or water bottle and use it as your jar.
  2. Add the dish washing
  3. You can drop in a piece of ripe fruit for adding extra temptation to the fruit flies.
  4. Fix a funnel at the mouth of the jar. If you don’t have a funnel, you can roll a paper into a cone shape leaving a half-inch opening at the bottom. You can even use the cut part of the bottle as described in step 1 as your funnel.

Since Apple cider vinegar is made from fermented apples, the fruit flies will be appealed to go down the funnel to reach the liquid. The dish wash soap breaks the surface tension so that the flies just can’t sit on the surface causing them to sink. If some flies don’t sit on the vinegar after entering the jar, they cannot find their way out, and will eventually drown. Still, if they don’t drown, you can place the arrangement in the freezer for 20 minutes.

Tips

  • If you want to make it without apple cider vinegar, you can use any other variety such as malt, rice or even the regular household (white distilled) vinegar.
  • In case you want to use no vinegar at all, replace it with orange, peach or apple juice.

Things Needed

  • Overripe banana
  • Plastic or Saran wrap
  • Warm soapy water
  • Toothpick

Instructions

  1. Place a couple of pieces of the banana at the bottom of a glass jar. A jam jar works fine. Your bait is ready.
  2. Cover the mouth of the jar with the plastic wrap. Use a rubber band or tape to secure the edges.
  3. Use the toothpick to poke tiny holes in the plastic.
  4. Place the jar in the common fruit fly infested areas of your house.
  5. Set one such jar just outside the door or window on a warm sunny day since that is usually their point of entry.
  6. When a considerable number of flies have been trapped, immerse the jar in a bucket of warm soapy water for 10 minutes to kill them.
  7. Rinse the jar and repeat the procedure.

  • You can replace the ripe banana with any overripe fruit.
  • Though ripe fruits work best for this method, honey, sugar water, maple syrup, molasses or lemon juice is also quite effective. Just leave a little of any of them in the jar and follow steps 2-7.
  • You can poke a tiny hole in the center of a coffee filter and stuff it in the jar to tape it in place instead of the plastic wrap.
  • One way to conveniently kill the flies is to put the flycatcher in the oven overnight, leaving its door partially open. In the morning, close the door and turn on the oven to get rid of any flies accumulated in the trap.

Venus flytrap Plant as a Natural Fruit Fly Catcher

Place a carnivorous Venus flytrap plant on your kitchen counter alongside a tomato bowl. The fruit flies gather around the plant attracted by the smell of the tomatoes. Even if they turn out to be too light to trigger the snapping mechanism of the plant, they tend to get stuck to the fly-attracting juice secreted by the living trap.
