If you have indoor tropical plants, you may have noticed small, flying insects hovering around the soil surface. These insects are most likely gnats, also known as fungus gnats. While they are not harmful to humans or pets, they can be annoying and can damage the roots of your plants. Luckily, there are several ways to get rid of gnats in your tropical plants.
Before you start treating your plants for gnats, you need to make sure that is indeed the problem. Gnats are small black or gray flies that are about 1/8 inch in length. They typically have long legs and antennae and are often found flying around the soil surface. You may also notice larvae in the soil, which look like small white worms.
One of the first steps in getting rid of gnats is to remove any infested soil from your plant’s pot. This is where the larvae live, so removing it will help eliminate the problem. You can either repot your plant with fresh soil or remove the top layer of soil and replace it with fresh soil.
Gnats thrive in moist soil, so letting the soil dry out can help eliminate them. Make sure to water your plants only when the top inch of soil is dry to the touch. Avoid over-watering and make sure that your pots have proper drainage.
Sticky traps are a great way to catch adult gnats. These traps are coated with a sticky substance that attracts and traps the insects when they land on it. You can purchase sticky traps at most garden centers or online. Place the traps near your plants and change them out frequently.
Gnat Nix is a product made from recycled glass that helps control fungus gnats by preventing them from breeding in the soil. It creates a barrier that prevents larvae from reaching the soil surface and becoming adults. Simply sprinkle the product on top of the soil and water your plants as usual.
Beneficial nematodes are microscopic worms that prey on fungus gnat larvae. They are a natural and effective way to control gnat populations in your plants. You can purchase them online or at some garden centers. Simply mix them with water and apply to the soil according to the package instructions.
