Monterey B.t. Biological Insecticide Concentrate


Naturally controls the worms and caterpillars that feast on 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. Choose your desired size below. Once ingested, Monterey B.t. causes disease in the digestive systems of worms and caterpillars. This sickness causes insects to stop feeding and die. Use Monterey B.t. Biological Insecticide on your fruits, vegetables, flowers, and shade trees. You can 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.
