Tiny White Bugs in Houseplant Soil: Fungus Gnat or Springtail Larvae

Identifying and Eliminating Tiny Soil-Dwelling Bugs

Terri sees 1–2 mm white bugs with legs in houseplant soil. Wants ID and damage assessment.

Expert Diagnosis from Darlene

Likely fungus gnat or springtail larvae—caused by overwatering. They thrive in constantly wet soil.

Treatment

• Water plant with rubbing alcohol (kills larvae).
• Then don't water again until soil is dry and pot feels light.
• They won't spread to other plants unless those are also overwatered.

Most plants need to dry well between waterings. Wet soil rots roots and attracts pests.
