Caterpillars and Cutworms

Caterpillars are the larval stage of moths and butterflies and are among the most common foliage-feeding pests found in home gardens. While some caterpillars eventually develop into beneficial pollinators, many species can cause significant damage during their feeding stage by chewing holes in leaves, consuming flowers, damaging fruits and vegetables, and, in severe infestations, completely defoliating plants. Common garden pests include cabbage worms, tomato hornworms, armyworms, loopers, and cutworms, which can affect a wide range of ornamental and edible crops.

Quick & Effective Sprays

When caterpillars start turning your garden into an all-you-can-eat buffet, quick action can keep plants healthy and thriving. Regularly check leaves for chewing damage and treat infestations early with Monterey B.T., which targets caterpillars as they feed. For larger outbreaks or when you need fast results, Bonide Eight Insect Control provides rapid knockdown and helps stop damage in its tracks. With routine scouting and timely applications, you can keep hungry caterpillars under control and your garden looking its best all season long.

Pesticide Free Caterpillar Control

If you'd rather skip pesticides, there are plenty of effective ways to keep caterpillars from taking over your garden. Start by regularly inspecting plants and hand-picking caterpillars and egg clusters from leaves, especially in the early morning when they're easiest to spot. Encourage natural predators such as birds, frogs, spiders, and beneficial insects by maintaining a diverse, pollinator-friendly garden. Lightweight floating row covers can prevent moths and butterflies from laying eggs on susceptible crops, while healthy soil and proper plant care help plants better tolerate minor feeding damage. Removing heavily infested leaves and keeping the garden free of plant debris can also reduce caterpillar populations before they become a major problem. With a little vigilance and a healthy garden ecosystem, you can successfully manage caterpillars without relying on chemical controls.
