No, they did not hunt for food they only grew food and traded for food.

By pests I guess you mean herbivores and if their food source was to be wiped out and that was there only food source they would die out too. - just imagine, what would happen to our diet and the food chain if all cows were wiped out? luckly we have other food sources like chicken (mmm), but what if we didnt?
