Safer Bt Caterpillar Killer - 8 oz.

  • Have you ever thought of using a beneficial bacteria like Bt to treat a pest problem?
  • Jean Ann, I use this product often in my gardening business to treat caterpillar damage on roses in particular. I try to keep it minimal, because caterpillars turn into butterflies (well, and moths), but for plants that realy need the help, this is easily the most sustainable spray out there. I do try hand picking them off, first.
