How to Get Rid of Flies in Houseplants

If you're a houseplant enthusiast, you know that caring for your plants can sometimes be a challenge. One common problem that many plant owners face is an infestation of flies in their houseplants. These tiny pests can be frustrating to deal with and can cause damage to your plants if left unchecked. Here are some tips for getting rid of flies in your houseplants and keeping them from coming back.

The first step in getting rid of flies in your houseplants is to identify the type of fly you're dealing with. There are several types of flies that can infest houseplants, including fungus gnats, fruit flies, and phorid flies. Each type of fly has its own unique characteristics and habits, so it's important to determine which type you're dealing with in order to effectively control them.

Once you've identified the type of fly, the next step is to determine the source of the infestation. Fungus gnats are often attracted to moist soil, so if you're dealing with these pests, it's likely that you're overwatering your plants. Fruit flies, on the other hand, are attracted to overripe or rotting fruit, so if you have fruit trees or plants in your home, they could be the source of the infestation. Phorid flies, also known as humpbacked flies, are attracted to decaying organic matter, so it's possible that you have a decomposing plant or soil that is attracting these pests.

Once you've identified the source of the infestation, it's time to take action. Here are some strategies you can try to get rid of flies in your houseplants:

    1. Reduce watering: If you're dealing with fungus gnats, one of the most effective ways to get rid of them is to reduce watering. Fungus gnats are attracted to moist soil, so by allowing the soil to dry out between waterings, you can help to eliminate their breeding ground. Be sure to check the moisture level of the soil before watering and only water your plants when the top inch or so of soil is dry.
    2. Remove any decaying matter: If you have a plant that is beginning to decay, it's important to remove it as soon as possible. This will help to eliminate the attraction for phorid flies and other pests that are attracted to decaying organic matter.
    3. Use sticky traps: Sticky traps can be an effective way to catch and kill flies. Simply place the traps near your plants and the flies will get stuck on the sticky surface. Just be sure to replace the traps regularly to keep them effective.
    4. Use natural predators: Some plants, such as Venus flytraps, are natural predators of flies and can help to control an infestation. You can also introduce beneficial insects, such as predatory mites, to your plants to help control the fly population.
    5. Use a chemical control: If all else fails, you can try using a chemical control to get rid of flies in your houseplants. There are several products on the market that are specifically designed to control fly infestations, such as insecticidal soap or neem oil. Just be sure to follow the instructions on the label and use caution when applying these products, as they can be toxic to pets and humans.


It's also a good idea to allow excess water to drain away from the base of the plant, as this can help to prevent standing water from accumulating around the roots. Using a well-draining soil mix and pots with drainage holes can also help to reduce the risk of overwatering.

In addition to reducing watering, it's a good idea to remove any dead leaves or other debris from the soil surface. This will help to eliminate any additional breeding grounds for the flies and keep your plants healthy and happy.

By following these simple steps, you can effectively control fungus gnat infestations and keep your plants healthy and free of pests.
