How do you stop flies on indoor plants?

Answered by Jeremy Urbaniak

To stop flies on indoor plants, there are several methods you can try. Here are some effective ways to get rid of those pesky insects and keep your houseplants healthy:

1. Adjust watering habits: One common reason for the presence of flies, specifically fungus gnats, is overwatering. These gnats are attracted to moist soil. To combat them, allow the top inch of soil to dry out before watering your plants again. This will discourage the gnats from laying eggs in the soil.

2. Add dry soil or sand: Another way to prevent flies is by adding a layer of dry soil or sand to the top of the potting mix. This creates a barrier that makes it difficult for the flies to access the moist soil where they lay their eggs.

3. Use gravel mulch: Applying a layer of gravel or decorative stones on top of the soil can also deter flies. The stones create a physical barrier that prevents the flies from reaching the soil.

4. Consider sticky traps: Sticky traps are effective in catching adult flies. These traps consist of adhesive surfaces that attract and capture the flies when they land on them. Place the traps near your plants to help reduce the fly populations.

5. Try insecticidal soap/spray: Insecticidal soap or spray can be used to control small flies on indoor plants. These products are safe for most houseplants and can be effective in eliminating the adult flies. Follow the instructions on the product label for application and safety guidelines.

6. Use neem oil: Neem oil is a natural insecticide derived from the neem tree. It is effective in controlling a wide range of pests, including flies. Dilute the neem oil according to the instructions on the packaging and apply it to the affected plants. Repeat the application as needed.

Remember to always read and follow the instructions on any products you use to ensure their safe and effective use. It’s also important to regularly check and inspect your plants for signs of pests, as early detection can prevent infestations from spreading.

In my personal experience, adjusting watering habits and adding a layer of dry soil or sand on top of the potting mix have been effective in controlling flies on indoor plants. I have also used sticky traps, and they have helped in reducing the number of adult flies in my house. Neem oil has also been helpful in controlling various pests, including flies, on my plants.

By implementing these methods and regularly monitoring your plants, you can effectively control and prevent flies from infesting your indoor plants, creating a healthier environment for both you and your plants.
