Caterpillars on Cannabis (Budworms)

Cannabis caterpillars — usually corn earworms or tobacco budworms — bore INTO buds and eat them from inside. By the time you see damage, they're already eating your harvest.

What it looks like

●Small holes in leaves (early)
●Dark crumbly frass (poop) in bud crevices
●Wilting buds with brown rotten spots
●Small green worms inside buds when you inspect

Quick diagnostic checks

1BT (Dipel, Thuricide) is the gold standard — safe and effective

2Hand-pick any visible caterpillars

3Cut out any bud with frass visible — rot spreads fast
