Worms are eating my petunias, how do I get rid of them?

I keep picking them off and killing them and they just come back. Hardly any of my plants have flowers becasue the worms are eating them overnight. Does anyone have a solution to this. I have sprayed them with pestisides but it didn't work.

Worms are eating my petunias, how do I get rid of them?
One of the most common pests of petunias is the budworm caterpillar. These small green worms often appear in late June and July. You won't often see the worm itself. Instead, you'll see the droppings, which often are described as small black seeds. The worms feed on the flower buds, making small holes in the buds and the leaves.

These caterpillars are difficult to control but Bacillus thuringensis (B.T.) and Bifenthrin are reasonably effective insecticides. If left unchecked, the presence of the caterpillars will cause petunias to stop blooming.
Reply:Paper tiger's answer is bang on the dot! BT is very effective.
Reply:Excellent answer above, and just one thing I want to add: "“use thick organic mulch to inhibit migrating larvae” (Encyclopedia of Garden Plants) or handpick the beetles, larvae and eggs. To remove the problem chemically, Neem, Pyrethrins and Rotenone can be used."
Reply:dish soap deluted in an old windex bottle washed clean.
