Why Do My Houseplants Have Gnats?

Houseplants can often be a major attractor for pests. Many wonder why these plants draw so much attention. Gnats are a common culprit, drawn to the damp soil of houseplants where they lay their eggs. These annoying bugs, who more specifically are often fungus gnats, can also cause major damage to houseplants through their feeding habits.

What Are Gnats Anyway?

Commonly mistaken for tiny mosquitoes or fruit flies, gnats are flies that are slender and have long legs. They are actually a part of the Orfelia and Bradysia species. Gnats will not bite people or pets, but they can do damage to houseplants and are known for being particularly annoying. The adults will grow to be about 1/16th to 1/8th inch long. Many of the gnats found near houseplants will be fungus gnats, a particular kind of gnat that is attracted to damp soil.

Why Are Gnats Drawn to Houseplants?

The main threat that fungus gnats pose is typically not directly to the plants. Their larvae are the real issue, which will damage the feeder roots of the plants causing leaves to wilt and the plant to die if left unaddressed. Fungus gnats are particularly attracted to the environment of houseplants to lay their eggs. The organic debris, wet soil, and a steady light source all give a green light for gnats to settle there.

How Do I Get Rid of Gnats from My Houseplants?

There are several simple solutions to your gnat problem. An easy solution is letting the soil of your plants dry out for a few days. The dry environment will deter the fungus gnats. If that doesn’t quite do the job, traps can be an intriguing next step. These include:

  • Vinegar trap. Place a bowl of 1 cup white vinegar and 2-3 drops of dish soap by your plants. The solution attracts gnats and they should fall right in.
  • Sticky fly traps. These store-bought traps are brightly colored pieces of paper that attract gnats to fly into them and become stuck.
  • Potato traps. Simply place pieces of potato flesh side down in the soil of your plants and check under them every few days to remove any feeding larvae. Replace the potatoes each time and continue until the gnats are gone.

 

How Do I Prevent Gnats in the Future?

One way to prevent these annoying pests from coming back would be to separate your potted plants from each other; this can help stop gnats. This is an easy step to take before you begin attempting more involved methods. Additionally, ensuring your plants aren’t overwatered can help keep gnats from returning. Overwatered plants invite gnats to come and stay awhile as an opportune breeding ground.
