Safer® Brand Caterpillar Killer with B.t.

Safer® Brand Caterpillar Killer with B.t. (bacillus thuringiensis var. Kurstaki) is an effective organic solution for caterpillar and worm control. Caterpillar Killer kills worms and caterpillar stage insects, but has no effect on birds, earthworms, or beneficial insects, such as honeybees and ladybugs, when used as directed. Worms and caterpillars eat treated foliage then immediately stop feeding and damaging plants.

Effective for: Cabbage looper, imported cabbage worm, tomato hornworm, bagworm, spring cankerworm, fall cankerworm, gypsy moth, tent caterpillar, elm spanworm, fall webworm.

How it Works

When the B.t. is ingested by the worm, it works as a gut rot poison that makes the worm stop feeding. The caterpillar or worm will stop feeding immediately and die within days of malnutrition. This caterpillar killer will keep your lawn and organic garden, free from caterpillars all year long.

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 Caterpillar Killer when pests are first noticed and repeat every 5-7 days or as necessary. Caterpillar egg hatching 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.
