What type of insect would mostly through eat pepper plants and how do I get rid of them?

I have three types of herbs in my garden, two types of pepper, and tomato. I have noticed that something was eating through my pepper leaves and ignoring the tomato plant. What would that be and how do I get rid of it?

Answers:
Any number of moth caterpillars or beetles might be the cause. You didn't say the pests were eating your peppers themselves so you still have time. The problems with using dusts and other quick-fix chemicals is that they kill good bugs along with the bad. This leads to worse problems.

Plant marigolds near the peppers. They have a natural insecticide called piperazine which kills pests. Also look at garlic, onions and rosemary to plant near peppers.
