Updated: July 23, 2022

Gnats are tiny flying insects that can be a nuisance to gardeners, especially those who grow echinacea plants. These pests can quickly infest your plants and cause damage to the leaves and flowers. If you have noticed gnats hovering around your echinacea plant or have seen signs of damage, it is time to take action. Here are some tips on how to get rid of gnats in echinacea plants.

Identify the Type of Gnats

There are several types of gnats that can infest your echinacea plant. Fungus gnats are the most common type that is attracted to moist soil in houseplants or outdoor gardens. They lay their eggs in damp soil, and the larvae feed on organic matter, including roots.

Use Sticky Traps

One effective way to get rid of gnats is by using sticky traps. These traps work by attracting the gnats with a sweet scent and then trapping them on a sticky surface. You can purchase sticky traps at your local gardening store or make your own by coating yellow index cards with petroleum jelly.

Change the Soil

If fungus gnats have infested your echinacea plant, changing the soil may be necessary. Fungus gnats thrive in damp soil, so replacing the soil with fresh, dry soil can help eliminate them. Be sure to let the soil dry out completely before watering again.

Use Neem Oil

Neem oil is an organic insecticide that is effective against a variety of pests, including gnats. Mix one teaspoon of neem oil with one quart of water and spray it onto the echinacea plant’s leaves and soil. The neem oil will suffocate the gnats and their larvae.

Allow the Soil to Dry Out

Gnats thrive in moist environments, so allowing the soil to dry out completely can help eliminate them. Be sure not to overwater your echinacea plant, and allow the soil to dry out between waterings. You can also improve drainage by adding sand or perlite to the soil.
