What to know before buying

Listing details to confirm

The listing's 1000 ml liquid-volume entry does not align clearly with its powder form and 16-ounce weight. It also spells the active ingredient claim as “bacillus thoringiensis,” while the title identifies the product as BT. Confirm the product label and directions, targeted pests, application rates, and any site or harvest restrictions before use. Customer feedback also differs on durability in sunlight, so follow label directions for repeat applications.
