How To Make a Homemade Fruit Fly Spray

Using pesticides in the kitchen or around the house is not safe, especially if you have allergic family members and pets. Therefore, learning how to make a natural homemade fruit fly spray is important.

To make a homemade fruit fly spray, pour 1 cup of warm water into a hand spray bottle, then add 5 teaspoons of peppermint oil. Spray the solution directly on the fruit flies to repel them. Alliteratively, you can use other essential oils like lavender, eucalyptus, and basil.

6 types of homemade fruit fly sprays

You can use several alternatives to make spray when you have a fruit fly infestation. Here are the 6 best homemade sprays you can use to get rid of fruit flies:

1. Dish soap homemade fruit fly spray

You can use dish soap to make a fruit fly spray at home. Dish soap spray can kill fruit flies because it contains chemicals like borax, which can quickly dehydrate and choke fruit flies. Here is how to make a homemade fruit fly spray using dish soap:

  1. Pour 1 cup of warm water into a spray bottle
  2. Add 1/4 cup of dish soap and shake to mix
  3. Spray the solution directly on the fruit flies and watch them die

You can spray this on the counters, tables, and floor after moping to ensure that they do not land there, especially if you have an infestation.

It is still okay to mix a few drops of basil essential oil with 1/4 cup of water to spray on the fruit flies. For best results, ensure that the water is warm and pure.

3. Peppermint homemade fruit fly spray

Peppermint has been used over the years to repel insects like ants, house flies, and fruit flies.

Peppermint can kill fruit flies when they come into contact with it because it contains Pulegone which causes nausea and rapid dehydration.

  1. Pour 1/4 cup of warm water into a spray bottle
  2. Add 4 tablespoons of peppermint oil
  3. Mix and spray the solution directly on the insects

You should always use those sprays after cleaning the house and removing anything that may attract fruit flies. If this is not done, those flies will keep returning, and the valuable oils will be wasted.

  1. Pour 1/2 cup of water into a spray bottle
  2. Add 5 teaspoons of lemon eucalyptus essential oil

  4. Mix the solution and spray directly on the flies

This is one of the best homemade sprays for fruit flies because the vodka will also help in choking them after the lemon eucalyptus makes them dizzy.
