Night-Feeding Caterpillars and Slugs Devouring Bougainvillea and Jasmine

Rapid Defoliation in Cape Coral: Nocturnal Pests

Bougainvillea and night-blooming jasmine stripped of leaves in 1–2 nights, cutworm found on jasmine: night-feeding caterpillars and/or slugs.

The Culprits

• Night caterpillars: Hide in soil by day, feed in canopy at night. Strip plants rapidly.
• Slugs/snails: Also nocturnal, leave slime trails, prefer tender growth.
• Cutworms: Soil-dwelling, cut stems at base, climb to feed.

Control: Granular Insecticide

1. Triazicide (gamma-cyhalothrin) granules broadcast around plants
2. Water in thoroughly—activates, moves into soil zone
3. Controls soil-dwelling and foliage-feeding pests
4. Reapply per label (typically 4–6 weeks)

Cultural Practices

• Trim damaged growth for aesthetics
• No fertilizer now—tender new growth = pest magnet + frost risk
• Bougainvillea: water sparingly (drought = more color)
• Jasmine: weekly deep soak appreciated

Safety Note

Granulars affect beneficials. Apply late evening. Avoid flowering plants visited by bees.
