There are several ways to eliminate flies from house plants. Some of these solutions include limiting the watering of your plants, and using insecticides. These insecticides target flies in two stages of their life cycle: the larval stage and the adult stage. These methods are effective for reducing the flies’ population, but must be applied frequently. Another simple method is to use hydrogen peroxide. Mix some of the chemical with water and soak the soil. This solution will kill larvae and other pests that can make a nest in your plants.
Flies are not necessarily harmful to plants, but they can do a lot of damage. They can cause stunted growth and wilted leaves when they feed on fruit and vegetables. Certain types of plants are more prone to attracting flies than others. They can even cause problems with your indoor plants if they’re kept in stagnant water.
Besides larvae that feed on houseplant roots, fungus gnats can also inhabit your plants. Fortunately, these flies don’t cause any harm to your plants. Other types of flies, like houseflies, eat manure, dead animals, and rotten wastes. They often lay their eggs in dirty areas and prefer moist conditions.
While most flies don’t lay eggs in house plants, you can try trapping them with natural products. You can purchase a yellow sticky trap, which is easily available in the market. This will trap the flies and their larvae, thereby killing them.
