Tiny Bugs in Houseplant Soil: Identification & Action

Common Soil Dwellers

Microscopic light-colored bugs on pot bottoms are usually harmless springtails or soil mites. They feed on decaying organic matter and indicate moist, organic-rich soil.

When to Worry

If you see tiny black flying gnats, that's a fungus gnat infestation requiring treatment. Otherwise, no action needed.

Preventive Practices

• Allow soil to dry more between waterings.
• Use sterile, well-draining potting mix.
• Avoid organic debris on soil surface.
• Don't let food/drink spill into pots.

If Treatment Needed

For fungus gnats: top-dress with sand/diatomaceous earth, use potato slices to trap larvae, or apply biological control (Bti).
