Naturally controls the worms and caterpillars that feast 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-quart bottle. Once ingested, Monterey B.t. causes disease in the digestive systems of worms and caterpillars. This sickness causes the insect to stop feeding and they eventually die. Use Monterey B.t. Biological Insecticide on fruits, vegetables, shade trees, and flowers. You can safely apply Monterey B.t. Biological Insecticide any time, including the day of harvest. 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.
