Fruit flies can be a nuisance to freshwater plant owners. These tiny insects can lay their eggs on the leaves of your plants and their larvae can cause damage to the plant’s roots. Fortunately, there are ways to get rid of fruit flies without harming your plants.

Identify the Source

The first step in getting rid of fruit flies is to identify the source of the infestation. Check the soil and leaves of your plants for any signs of fruit fly activity. You may also notice small, dark spots on the leaves or fruit fly larvae on the roots of your plants.

Remove Affected Areas

Once you have identified the source of the infestation, remove any affected areas from your plants. This may include removing any dead leaves or pruning back infected branches. Be sure to dispose of these materials away from your other plants to prevent further spreading of the fruit flies.

Clean Your Plant Containers

Fruit flies can lay eggs in the soil and on the sides of your plant containers. To prevent re-infestation, clean your plant containers thoroughly before replanting. This can be done with a mixture of water and vinegar or with a commercial disinfectant.

Use Sticky Traps

Sticky traps are an effective way to catch fruit flies. These traps can be purchased at most gardening stores and are easy to use. Simply place the trap near your plants and wait for the fruit flies to get stuck.

Use Natural Repellents

There are several natural repellents that can be used to deter fruit flies from your plants. These include:

  • Apple cider vinegar: Fruit flies are attracted to the scent of apple cider vinegar. Fill a small dish with apple cider vinegar and a few drops of dish soap. The dish soap will break up the surface tension of the vinegar, causing the fruit flies to sink and drown.
  • Essential oils: Peppermint, eucalyptus, and lemon essential oils can be mixed with water and sprayed on your plants to repel fruit flies.
  • Neem oil: Neem oil is a natural insecticide that can be mixed with water and sprayed on your plants to kill fruit flies and their larvae.
