Caterpillar Killer Garden Dust - description

The Safer® Brand Garden Dust utilizes bacillus thuringiensis (var. kurstaki) to eliminate caterpillars and worms from fruits, vegetables, lawns, flowers and ornamentals. When the B.t. is ingested by the worm, it works as a gut rot poison that makes the worm stop feeding. After the caterpillar or worm stops feeding, it will die within days of malnutrition. Safer® Brand Garden Dust is OMRI Listed® and compliant for use in organic gardening.


It is recommended that this product be applied late in the afternoon or on cloudy days since B.t. breaks down in the sunlight.


Carefully read and follow all directions on the product's label. B.T. is very specific and only works on caterpillars and leaf feeding worms.

It is recommended with any pesticide to test plants for sensitivity to the product. Spray a small section of the plant in an inconspicuous area and wait 24 hours before full coverage.


Application Rates:

  • Apply Safer® Brand Garden Dust when pests are first noticed and repeat every 7-10 days or as necessary. Caterpillar egg hatch can occur over an extended period of time.
  • Monitor treated areas for the presence of newly hatched pests and retreat if necessary.
  • Thorough leaf coverage is necessary for effective control. After ingesting a treated portion of the leaf, caterpillars stop feeding in a few hours and death occurs in a few days.
  • Apply at a rate of 2 to 3 ounces per 50 feet of row plantings.
