If i have cabbage aphids on my broccoli plants and i have sprayed bt, will it kill the aphids when they eat the leaves?

All 4 of the current answers are nonsense. It kills caterpillars and worms and the moth or butterfly eggs which produce the caterpillars. It is harmlees to other types of insects and harmless to humans. You CAN spray this on edible vegetables. It is a bacteria and no more harmful to humans than acidophilus in yogurt. Search [organic spray for aphids]. I found a product called Organicide which is safe for bees, ladybugs (they eat aphids) and butterflys. It contains SESAME OIL as its active ingredient. Neem oil will control aphids and many other pests, molds, mildews and other fungi. However, Neem Oil has a nasty taste and smell. I wouldn't recommend spraying the actual florettes.

Can this product be used as preventative measure and how often? Thank you!

Thuricide is based on a bacteria (or group of bacteria) that infect a variety of caterpillars. It takes 4 days for the caterpillars to die from the caterpillar, so reapplying less than 4 days is a waste. This is my 1st year with Thuricide. I found one large Tabacco Hook Worm on tomatoes. Applied Thuricide and never saw any more, live or dead. I applied more about 10 days later (there was a break in the daily rain), and again in about another 14 days. Never saw more caterpillars. So I quit applications. Just my observations. Not a study.

does it kill beneficial bugs and worms

It kills caterpillars, some caterpillars grow up to be beautiful beneficial butterflies and others crop pest moths. Spray only on plants You want to protect and spray carefully.

will it kill army worms

Yes, it will. It may take up to 4 days after application, and make sure there is no rain or sprinklers to wash it off or you'll have to reapply. The key is to make sure you are applying to the leaves, not necessarily the ground or the army worms. The formula must be on their food source so it can get into their digestive system. It basically kills from the inside out.
