fungus gnats on Parlor Palm
Quick answer
If your Parlor Palm has fungus gnats, the most likely cause is: Fungus gnats are small flying insects that thrive in consistently moist soil—exactly the conditions parlor palms prefer. While adult gnats are harmless and annoying, their larvae feed on organic matter and fine root hairs, potentially stressing the plant. The presence of gnats usually indicates soil that is staying wet for too long.
Start here:
- 1. Allow top 1-2 inches of soil to dry between waterings—this kills larvae and deters adults from laying eggs
- 2. Use yellow sticky traps to catch adult gnats and monitor population
