Eco-Caterpillar Killer is a certified organic biological insecticide designed to control leaf-eating caterpillars on vegetables, herbs, fruit trees, vines, shrubs, flowers, and ornamentals. Its active ingredient, Bacillus thuringiensis var. kurstaki (BtK), is a naturally occurring soil bacterium that specifically targets caterpillars without harming humans, pets, beneficial insects, or wildlife.
Once caterpillars consume treated foliage, feeding stops within hours and death follows within 3–4 days. This makes it an effective and environmentally responsible alternative to broad-spectrum chemical sprays. Supplied in easy-to-use sachets, Eco-Caterpillar Killer provides precise mixing with minimal waste, ensuring consistent results in home gardens and organic growing systems.
