Used for the control of caterpillars and Box Tree Moth. 100 mL bottle makes 30L 500 mL bottle makes 150L BTK is NOT a chemical pesticide but a microorganism that kills caterpillars - Bacillus thuringiensis var. kurstaki. Caterpillars stop eating as soon as they ingest this natural bacteria and will die a few days later. Very low application rates required for effective control. A biological insecticide, it controls caterpillars, including cabbage worm, tomato hornworm and many more. May be used on vegetables, fruit, shade trees, ornamentals and evergreens. Bio Protec is non-selective - Monarch Butterfly larva only feed on milkweed - so be careful when spraying! Show more
