Leafroller Caterpillars in Container Plants: Identification & Control

What You Found: Leafroller Caterpillars

The "cigar-rolled" leaves with caterpillars inside are classic leafroller damage. Moths lay eggs on leaves at night; larvae hatch, spin silk, roll leaves for shelter, and feed inside.

Immediate Steps

1. Remove and destroy all rolled leaves (don't compost).
2. Inspect at night with flashlight—pick off caterpillars.
3. Spray with horticultural oil or spinosad—penetrates rolls better than contact sprays.

Prevention

• Keep area clean—remove fallen leaves/debris.
• Attract birds—natural predators.
• Check nearby trees/shrubs—source of moths.

Leafrollers rarely kill plants but distort growth. Vigilance and early removal prevent spread.
