Thuricide BT Caterpillar Control

Yes, it is considered low-toxicity to humans and pets. However, as with any garden treatment, it is best practice to keep children and pets out of the immediate area until the spray has completely dried.

Absolutely. Because it is OMRI listed for organic gardening, it is safe to use on vegetables, fruits, and herbs. You can harvest your produce shortly after application, though it is always recommended to wash your vegetables thoroughly before eating.

No, and that is one of its main benefits. Thuricide BT is a biological control agent that specifically targets lepidoptera larvae—caterpillars and worms—while leaving beneficial insects like bees, ladybugs, and predatory wasps unharmed.

This is a liquid concentrate, so it must be diluted with water before use. The standard application rate is 2 to 4 teaspoons per gallon of water. For best results, mix in a spreader-sticker to help the solution adhere to the leaves.

Not necessarily. Thuricide BT works by ingestion, meaning the caterpillars must eat the treated foliage to be affected. You may need to reapply the spray periodically, especially after rainfall or as new plant growth appears, to maintain consistent protection.
