Identifying Red Worms in Water Hyacinth Roots: Harmless Bloodworms

What They Are

The tiny red wigglers are bloodworms—midge fly larvae. They thrive in decaying organic matter on plant roots.

Harmless and Beneficial

Fish love them. They indicate a healthy, nutrient-rich environment. No control needed.

Winterizing Hyacinths

In cold climates, bring hyacinths indoors to a bright, cool tub. Keep roots submerged. Trim dead foliage. Return after frost.
