Even though cold weather is here, indoor gnats can still be a problem. Fungus gnats often plague homeowners during this time of year. They live in damp areas and are especially problematic around houseplants. These pests are also called winter gnats because they become apparent after gardeners bring in their plants for the winter.
At first glance fungus gnats look like small mosquitoes but they are much smaller and don’t bite. Fungus gnats are long grey or black flying insect with one set of wings, long legs and antenna. You may not notice them at first but as they multiply they begin to swarm when you water or otherwise disturb your plant or drain.
Unlike fruit flies, fungus gnats are not attracted to decaying fruit but to moisture and decaying organic matter. Besides living in houseplants, they also lurk around drains or other areas that collect water.
Fungus gnats are generally harmless to people but they are annoying and will damage your houseplants. They lay their eggs in the moist soil and the larvae eat the roots, which causes the leaves to yellow. The adults eat plant debris found on top of the soil.
To prevent fungus gnats, clean any dead leaves or other organic material from around your potted plants. Make sure the top inch of soil is dry before you water and don’t let liquid sit in the saucer. For plants that prefer damper conditions, add about a half-inch of sand to the top of the soil to discourage gnats. Remove standing water from any other areas of your home.
