Tropicals & Tender Perennials: Shredded cannas, 1 by minigrannie

When we lived in the country I grew several different varieties of cannas, which I loved. The foliage was always ugly though, due to the numerous grasshoppers we always had. Since we've moved back to town, I've slowly been building my collection back up, and even DH liked them because of the tropical foliage. Suddenly, 3 or 4 days ago the foliage in one of the canna beds looked as if it had been through Hurricane Katrina. I couldn't see any bugs, so couldn't figure out what it could be. I went out last night after dark with a flashlight and discovered they were covered in leaf rollers. I went out this morning and killed about 15 of them, but know this doesn't solve the problem. Anyone here have a simple solution for getting rid of them before they have completely destroyed the foliage?
