Identifying and Treating Tiny White Worms in Butternut Squash

Organic Control for Squash Vine Borers or Mealybugs

Tiny white worms in young butternut plants are likely squash bug larvae or mealybugs.

Best Organic Treatment

Bacillus thuringiensis (BT) powder is highly effective against caterpillars and larvae. Apply to foliage and stems. Available at garden centers or online (Gardens Alive, Planet Natural).

Additional Measures

Inspect leaves regularly; remove egg clusters.
Use row covers early in season.
Rotate cucurbit crops annually.

BT is safe for beneficial insects when used as directed.
