Caterpillars Eating Hot Peppers: Identifying the Culprit and Organic Control

The Pest: Likely Tomato Hornworm

The "mini brown corn cob" droppings are classic caterpillar frass. Even hot peppers get eaten—Manduca sexta (tobacco/tomato hornworm) tolerates capsaicin.

Organic Control Program

1. Daily scouting: Check leaf undersides, stems. Look for white eggs (crush them).
2. Apply Bacillus thuringiensis (Bt): Organic bacterial spray. Caterpillars stop feeding, die in days. Safe for humans, bees.
3. Reapply after rain and weekly during peak season.

Why Soil Change Won't Help

Moths lay eggs on leaves, not in soil. Changing containers doesn't prevent re-infestation.

Prevention

• Use row covers early season.
• Plant trap crops (dill, fennel) to attract beneficial wasps.
• Rotate nightshade crops annually.
