Bt (Bacillus thuringiensis)

Bacillus thuringiensis (Bt) is a naturally occurring soil bacterium that produces proteins toxic to certain insect larvae, especially caterpillars and beetles. When insects ingest Bt spores or toxins, these proteins dissolve in their gut, disrupting their digestive system and causing death. Bt is widely used as a biological pesticide because it targets specific pests without harming humans, pets, or beneficial insects like bees. It's safe, environmentally friendly, and an effective way to manage agricultural pests, reducing reliance on chemical pesticides.
