Naturally control the worms and caterpillars that feed on your plants!

Monterey B.t. Biological is an all-natural, OMRI-listed insecticide that targets worms and caterpillars. It contains the active ingredient kurstaki. Kurstaki is a subspecies of the naturally-occurring bacteria Bacillus thuringiensis. This is a one-gallon bottle. Once ingested, Monterey B.t. causes disease in the digestive system of the worm and caterpillar. The sickness causes the insect to stop feasting and will eventually die. Use Monterey B.t. Biological Insecticide on your fruits, vegetables, shade trees, and flowers. Safely apply Monterey B.t. Biological Insecticide any time, including the day of harvest. For best results, apply directly to your plants at the first sign of an infestation. Mix at a rate of 2 fluid ounces per 3 gallons of water. This mixture covers up to 1,000 square feet.
