Product Details

Controls worms and caterpillars on fruits,vegetables, ornamentals and shade trees.
Gardens Alive!® has been offering Bt, a naturally occurring bacterium for insect control, since 1984. Recommended for Imported Cabbage worm and Cabbage Looper, Green Step must be eaten to be effective. After ingesting the insecticide, worm sand caterpillars immediately stop feeding, though they may otherwise appear to be unaffected for several days. Best results are obtained by treatments when worms are actively feeding on treated, exposed foliage.

  • Kills worms and caterpillar-stage insects, but has no effect on birds, earthworms or beneficial insects, such as honeybees and ladybugs, when used as directed.
  • Worms and caterpillars eat treated foliage, then stop damaging plants.
  • Acceptable for use on edible plants up to the day of harvest.

  • Apply Green Step when worms or caterpillars are first noticed, then repeat every 5-7 days while active. Apply more frequently for heavy infestations.

I have always hand picked cabbage moth larvae off my cabbage and kohlrabi before. This product not only saved time but got the caterpillars before they were big enough to easily hand pick. Greatly reduced the damage. I highly recommend.

This stuff is safe and best of all works great! Especially effective on "tomato caterpillars"! Worm eats a little leafs, dries up and dies! Non toxic!

I first got some of this about 3 years ago to deal with "tomato worms", you know those green one's that you can see until theyre the size of your finger and have destroyed a lot of growth. This product is safe to use and best of all is very effective! I just ordered another as the one I got 3 years ago is finally empty. It makes a lot and you don't have to use much to get great results. Highly recommeded!
