Should I kill every insect I find in my garden?

No. Most insects are harmless or helpful pollinators and predators. Identify a pest before acting, since broad sprays kill more allies than enemies.

What's the best way to prevent garden pests?

Healthy plants in good soil, floating row cover to block egg-laying, companion flowers that draw predators, and crop rotation to break overwintering pest cycles.

Common Vegetable Garden Pests: An ID & Control Guide

Part of: Plant Problems & Pest Guides

Every vegetable garden gets pests, and that's not a sign you did anything wrong. A productive season is never a bug-free one; the trick is catching the few common vegetable garden pests that do real damage early and not wasting effort on the many that don't. This page helps you tell them apart and points you to the specific fix for each.

Look before you spray

Most insects in your garden are harmless or actively helpful — pollinators, and predators that eat the pests for you. Reaching for a broad spray at the first chewed leaf usually kills more allies than enemies and leaves you worse off. So identify the insect before you treat it. Check plants in the morning, look under leaves where eggs and pests hide, and learn the few species that actually do damage in your beds.

The common garden pests worth knowing

A handful of culprits cause most of the trouble, grouped by how they feed:

Sap-suckers — aphids, whiteflies, and spider mites (technically arachnids, not insects) cluster on stems and leaf undersides, leaving curled, sticky, or stippled foliage.
Leaf-and-fruit chewers. Tomato hornworms and cabbage worms strip leaves and bore into fruit, often overnight.
Stem and vine borers. Squash bugs and vine borers collapse whole squash plants from the inside.
Soil and seedling pests. Cutworms, slugs, and flea beetles hit young transplants hardest.

Prevention beats cure

The cheapest pest control happens before the pest arrives. Healthy plants in well-prepared soil tolerate damage that would set back a stressed one. Floating row cover keeps egg-laying moths and beetles off vulnerable crops entirely. And companion planting — tucking flowers among the vegetables — draws in the predatory insects that do the patrolling for you.

Rotate to break the cycle

Many pests overwinter in the soil right where their favorite crop grew. Moving each crop family to a new bed each year leaves emerging pests with nothing to eat, which is the logic behind crop rotation. Start there, and reach for the specific guides above when you need to deal with the pest actually in front of you.
