Thuricide Concentrate
Bacillus Thuringiensis Kurstaki for Caterpillar control


Thuricide is used to control caterpillars as needed. It a that is easy to mix and apply. Apply by hose or pressurized sprayers, mist blowers, or aerial application, 1/2 tsp to 4 tsp/gal of water depending on extent of infestation. Even a little squirt bottle may be used. We recommend that you get an ID on the caterpillar you are treating for. We don't want to kill the caterpillars that will turn into beautiful butterflies. The easiest way to use it is to just spray the specific plants you want to protect like your tomatoes for tomato hornworms. If you have planted dill to feed the Swallowtail caterpillars or milkweed to feed the Monarch larva- don't use dipel on these plants.

  • Use the Garden Syringe for precise BTK applications in insect holes like squash vine borer, tree, shrub and plant borers. $ 3.49 each

Advantages of using Thuricide

  1. Thuricide, unlike certain chemical insecticides, may be used anytime a specific caterpillar appears. Treated vegetables may be picked, washed and consumed anytime after spraying.
  2. People and critters can return to the treated area immediately after the spray has dried.
  3. The active ingredient in Thuricide, Bacillus Thuringiensis v. Kurstaki has been proven commercially to selectively affect only leaf eating caterpillars.

What insects can Thuricide be used to control?

Bagworms, Coddling Moth Larva, Gypsy Moth Larva (best when used on their 2nd or 3rd instars), Spring and fall cankerworms, bag worms, tent worms, fall webworms, California's red-humped caterpillar, cabbage loopers, imported cabbage worm, Diamond back moth larva, tussock moth, celery looper, hemlock looper, grape leaf folder, leaf miners, pine processionary moth, spruce budworm, jack pine budworm, tomato and tobacco hornworms and tomato fruitworms- to name a few.
