This one should be obvious, right? If you're trying to support insect life in your backyard, you don't want to use chemicals or other substances that kill them. Providing habitat is a bit different than gardening for aesthetics. Caterpillars need foliage to feed on, so you'll have to be tolerant of leaves with holes, or even plants that have been defoliated in some cases. Some caterpillars will even feed on the plants you intended to eat yourself, like dill or fennel (which are the host plants for black swallowtail larvae).
