Thuricide Concentrate is a biological insecticide for use on fruits, vegetables, shade trees, and ornamentals plants to treat a variety of leaf-feeding worms. Pests treated include bagworms, tent caterpillars, gypsy moths, cabbage loopers, and tomato hornworms. Hi-Yield Thuricide may be applied up to and including the day of harvest.
What is Thuricide?
Bacillus thuringiensis (Bt) (in the pest control form it is known as Thuricide) is a naturally occurring bacterium found in soils throughout the world. It is unique in that it offers unusual properties that make it useful for pest control, especially the control of leaf-feeding insects. This is because Thuricide reacts with the cells of the stomach lining of target pests, causing them to not be able to feed within hours after contact. The insects eventually die from starvation. The most common strain of Bt is the kurstaki strain which will kill leaf- and needle-feeding insects such as caterpillars and webworms.
Thuricide is generally considered beneficial in that it is naturally occurring and will not kill other non-target insects. For example, if Thuricide is applied to a vegetable garden, it will not kill honeybees or other pollinating insects. Also, Thuricide breaks down in sunlight within 1-2 weeks.
The Kurstaki Strain (Thuricide) will kill vegetable, fruit, tree and crop leaf-feeding insects such as the cabbage worm (cabbage looper, imported cabbageworm, diamondback moth, etc.), tomato and tobacco hornworm, European corn borer, Alfalfa caterpillar, alfalfa webworm, Leafroller, Achemon Sphinx, Tent Caterpillar, Fall Webworm, Leafroller, Red-humped caterpillar, Spiny elm caterpillar, western spruce budworm, pine budworm, and pine butterfly.

thuricide concentrate
By Roger on August 11, 2011
Verified PurchaseI decided to try thuricide, instead of killing tomatoe worms with sevin or other insecticide. I am always concerned about killing off the pollinators, along with the worms. I sprayed at 1 tblsp per gallon, and after 2 days the worms dropped off, so far it seems to work very well. The only question I have about the product that I can't find in any product written material, is; shoul I use the product before an infestation, to prevent it from happening in the 1st place?

Verified PurchaseTerrible problem with tent caterpillars in our apple & pecan trees. Applied Thuricide when tents started to appear and they were gone in a week. No signs of any tents after a month of treatment

Thuricide Concentrate can save waterlilies.
By Mike on July 8, 2011
Verified PurchaseI have used this recently as well as in the past, with 100% effectiveness. I am using it against the China Mark Moth larvae, and other larval insect pest, on my waterlilies. I do mix it strongly, as it is being used in a aquatic environment. 4 capfulls in a 16oz sprayer of water. I spray the pads in late evening, as strong sun will inhibit it's effectiveness. Most of the time, a single application will do the job. Worst case, 3 treatments, 3 evenings in a row. Side benefit, no a single, living mosquito larvae to be found in any of my pond, following the treatments.

Great for handling citrus-tree eating caterpillars
By Nick on November 12, 2011

They Live On!
By Andrew on February 7, 2012I did several Google searches on how to get rid of fungus gnats in house plants. Many recommended Thuricide. I gave the plants a good soil drenching and the gnats are still here . . . still annoying me. Oh well. I'm sure this stuff is good at killing other bugs, but not gnats.

no more swallowtail butterflies
By Ariel on June 3, 2012no more caterpillers. There is lots of new growth on my orange tree, which is what I was waiting for before I could review this product. So far I think it is great. I have sprayed it on everything, the Ixora had tent caterpillers, so did the Royal Poinciana tree. I mixed it with Epsom salts and fertilizer, sort of an all purpose growth enhancer. I will be buying more from this company. Thanks so much for the great information about how to take care of my yard myself. Ariel Hounshell

caterpillar killer
By Charles on December 19, 2011
Verified PurchaseDoes not do any good for caterpillars on oleander plants.
waiting for new growth
By Ariel on May 27, 2012Can't really tell yet, I have only used it twice so far, and I am still looking for new growth on my orange tree. Seeing results takes a few weeks I imagine. Still hopeful.
Bag Worm infestation!
By Myron on June 25, 2012We have a considerable infestation of Bag worms on mature Leland Cypress. I have applied this twice and saw good results both times. Active feeding worms were destroyed. I am not sure I have interupted the Bag Worm life cycle as of now and will be applying a third application today. If I can save the trees the rating will go to 5 stars
Works Effectively - Very impressed!
By A on November 11, 2012
Verified PurchaseAfter just one use on my vegetable garden there was a significant improvement in health of the leaves. The thuricide did its job in reducing the number of tomato horn worms feeding on my plants. It also worked very well on my bouganville plants that have been unhealthy for years. In just two weeks new plant growth is emerging. Great product and very effective! I highly recommend it. The only drawback is the strong order - use in well ventilated areas.

QCan Thuricide Concentrate be sprayed on the ground? Is it harmful to animals such as dogs?
AThuricide Concentrate is a very safe to use when the product label is followed. Be sure all pets and people are out of the area when Thuricide is being applied and they do not return until the area is dry. Thuricide Concentrate is labeled to be applied to fruits, vegetables, ornamentals and shade trees.
October 5, 2011Bert from Hickory, Nc asked:
QAfter Thuricide is applied how long till the vegetable is safe to eat?
AAccording to the the Thuricide product label you may apply Thuricide up to and on the day of harvest.
December 22, 2011Debra from Lagrange, Ga asked:
QCan thuricide concentrate be used as a drench to kill fungus gnat larve in house plants?
AThuricide concentrate is actually not labeled for fungus gnat larvae and so we are not sure of how effective it would be. However, we do sell a product called Talstar One which is what we have always recommended for fungus gnats and works great. You should also place your plants outside to dry out a little bit or cut down on how often you water them, if possible, and this will also decrease the fungus gnat reproduction cycle.
April 13, 2011Mary asked:
QDoes Thuricide Concentrate fall into the pyrethroid category?
ANo. Thuricide is made up of Bacillus thuringiensis (Bt) which a naturally occurring bacterium found in soils throughout the world. Pyrethroids are synthetic man-made insecticides.
July 10, 2011Brad asked:
QCan Thuricide be used along with Spinosad to be more effective against borers and larvae?
AWe believe the answer is yes, but just to make sure we would recommend calling the manufacturer of Thuricide since they are the true experts on their own product. You can reach them at 888-583-5296.
