Not for Gnats!!
By dw
Do your own research. Apparently there are two strains or subspecies of BT (Bacillus Thuringiensis), and this one (kurstaki) is only for moth larvae and caterpillars. The strain for gnats, small fly, and mosquito larvae is a different one (israelensis). I read a previous seemingly informative review on this product, which in fact endorsed it for my problem - fungus gnats in household plants. (As does the listed description - "Worm Killer and Gnat Control") Largely based on that review I purchased Thuricide, but on its arrival found that the application guide didn't mention gnats. Doing more investigation led to an extension office handout (university based) explaining about the different strains. I'm still confused about the review, but believe it is inaccurate! Bottom line seems to be sure to get Bacillus Thuringiensis subspecies israelensis for gnats!

Even better than I expected!
By W. Melillo
After budworms had reduce my petunia flowerbox to skinny green leaves and only one lonely flower, I decided to try B.T. rather than a harsh aerosol poison. I had a very difficult time finding this product in the stores in my area (eastern PA), so orderd through Amazon.
The product arrived quickly and after only two weekly applications my flowerbox is bright, blooming and filled with flowers once again.
I am thrilled and so are the bees and hummingbirds which visit my other plants.
No kidding this stuff is great !!!

Excellent product
By Plant Princess
For a belts-and-suspenders approach to inchworms. Use Tanglefoot on the trunks of affected trees in April and use Thuricide spray in May on your plants. It's very economical - as opposed to paying someone and arm and a leg to do the spraying for you! - and extremely effective. Note: I spray every morning, using a Black and Decker portable battery sprayer. A life-saver for plants.
