Safer Caterpillar Killer II Concentrate Insecticide - Outdoor Use - 16 oz

Safer Brand 16 oz Caterpillar Killer II Concentrate is a powerful caterpillar killer spray designed to control caterpillar and worm infestations on your outdoor plants. This caterpillar insecticide targets the caterpillar stage of insects, including tent caterpillars, gypsy moths, cabbage loopers, and tomato hornworms, while remaining safe for birds, earthworms, and beneficial insects when used as directed. The active ingredient, Bacillus thuringiensis var. kurstaki (B.t.), works by causing caterpillars and worms to stop feeding immediately after ingestion, providing fast and effective caterpillar control. For best results, apply this caterpillar spray in the late afternoon or on cloudy days, as sunlight can break down the B.t. Safer Brand Caterpillar Killer II is OMRI Listed, making it suitable for organic gardening and safe to use up until the day of harvest. This 16 oz insect killer concentrate is easy to use—simply mix with water and spray directly onto affected plants. Ideal for gardeners seeking a reliable caterpillar pesticide, this product offers targeted protection for your garden without harming the environment.
