Southern Ag Thuricide BT Caterpillar Control
Southern Ag Thuricide BT is a biological insecticide containing Bacillus thuringiensis (Bt) designed to control destructive caterpillars and worms on vegetables, ornamentals, and garden plants.
When caterpillars ingest Bt-treated foliage, the bacteria disrupt their digestive system, stopping feeding and ultimately eliminating the pest. Thuricide BT is widely used by gardeners, organic growers, and greenhouse producers for safe and effective caterpillar control.
Because it specifically targets larval caterpillars, Thuricide is safe for beneficial insects, people, pets, and wildlife when used according to label directions.

Active Ingredient
Bacillus thuringiensis var. kurstaki (Bt)
This naturally occurring soil bacterium produces proteins that specifically target caterpillar larvae when ingested.
How Thuricide Works
Thuricide BT works as a stomach poison for caterpillars. Once larvae consume treated foliage:
-
Feeding stops quickly
-
The digestive system is disrupted
-
The caterpillar dies within a few days
Because Bt must be eaten, thorough leaf coverage is important for best results.
