    A: Yes, this product is effective against bagworms when the caterpillars are small, typically between 1/8 to 1/4 inch. For the best results, treatment should generally begin in May and may require four to five applications to achieve full control.

  • A: The active ingredient, BTK, is very effective when the caterpiller inside the bag are very small. The best time to spray is when the bagworm caterpillars are small - 1/8 to 1/4 inch. It may now be too late in the season to effectively treat bagworm with this product. Generally treatment should start in May and 4 or 5 treatments may be need to control the bagworms.
