Safer's BTK Biological Insecticide is a natural, bacteria-based liquid spray used to control leaf-eating caterpillars like cabbage worms and tent caterpillars on fruits, vegetables, and trees.
How It Works:
Active Ingredient: Bacillus thuringiensis subsp. kurstaki, strain ABTS-51.
Action: Caterpillars must eat the treated leaves. They stop feeding within hours and die in a few days.
Safety: Safe for humans, pets, bees, and birds; it only targets specific moth and butterfly larvae
