Answer: Look for silvery or slimy trails. If you find them, snails or slugs are at work and Sluggo will control them. If not, look for frass (bug poop) on the soil surface. If you find black pellets, caterpillars are feeding on the leaves and Bt (Dipel or Thuricide) will control them. If you can't find frass, the culprits are beetles. Look on the undersides of the leaves and hand pick any you might find. If there are no insects anywhere, they've already done their damage and have moved on so no chemical controls will be necessary. Hope you figure out who or what has been feasting on your marigold leaves!
