Mystery Soil Bugs in New Houseplant: Alcohol Soil Drench

You have a new, unidentified "small tree" with dark, centipede-like bugs in the soil that react to water. Without a plant ID or bug photo, exact ID is impossible—but the fix is universal.

Immediate Treatment

1. Fill a spray bottle with 70% isopropyl (rubbing) alcohol.
2. Spray all leaf surfaces (top/bottom) and soil surface thoroughly.
3. Water the plant with the alcohol (diluted 1:1 with water) to kill soil pests.
4. Repeat weekly for a month.

Cultural Correction (Likely Root Cause)

• Stop overwatering. Water only when nearly dry (pot feels light).
• Maximize light. Bright, direct sun if possible.

The bugs (likely springtails or beetle larvae) thrive in wet, low-light conditions. Fix the environment, and the plant will outgrow the infestation.
