Ferti-lome® Caterpillar Killer Spray w/BT

Ferti-lome® Caterpillar Killer Spray with Bt targets the most damaging leaf-feeding caterpillars and worms in the home orchard and vegetable garden — bagworms, tent caterpillars, gypsy moths, cabbage loopers, tomato hornworms, and more — with a naturally occurring biological insecticide that’s completely non-toxic to humans, pets, birds, and beneficial insects including bees. The active ingredient is Bacillus thuringiensis (Bt), a naturally occurring soil bacteria with a decades-long track record in organic pest management. Safe to apply right up to harvest day. Apply to fruits, vegetables, shade trees, and ornamentals.

Bt — A Natural Biological Insecticide

Bacillus thuringiensis is one of the most trusted and widely used biological pest controls available — a naturally occurring soil bacteria that’s specifically toxic to caterpillars and leaf-feeding worms through a biological mechanism that only affects this category of pest. When caterpillars ingest Bt on treated foliage, it disrupts their digestive system and stops feeding within hours, with death following in 1–3 days. Humans, pets, birds, bees, and beneficial insects are completely unaffected — the mechanism simply doesn’t work on them.

Targets the Most Damaging Orchard and Garden Caterpillars

The pest coverage focuses on the most damaging leaf-feeding caterpillars home orchardists and vegetable gardeners encounter: bagworms, tent caterpillars, gypsy moths, cabbage loopers, and tomato hornworms — along with additional leaf-feeding worms listed on the label. Apply when caterpillars are first noticed, then repeat every 5–7 days while they remain active. Apply thoroughly to the top and bottom of foliage where caterpillars feed. Apply more frequently during heavy infestations.

Use to Harvest — No Pre-Harvest Interval

Ferti-lome® Caterpillar Killer Spray with Bt has no pre-harvest interval — it can be applied right up to and including harvest day, making it practical to use throughout the entire growing season whenever caterpillar pressure is present.
