Controlling Fungus Gnats in Venus Flytrap Pots: Pyrethrin Treatment and Reapplication Schedule

Small flies in soil are likely fungus gnats. Larvae eat roots—we've lost many plants to them.

Treatment

• Water-based pyrethrin spray (Safer Brand) on soil. Avoid soap-based insecticides.
• Apply in early evening (breaks down in sun).
• Repeat in 7 days to kill newly hatched larvae.
• Then as needed.

Good growing!
