One evening your tomato plant is lush, green, and loaded with fruit. The next morning? Large sections of leaves have disappeared, stems are bare, and you can't figure out what happened. The culprit may still be there... Blending in almost perfectly with the leaves is one of the largest—and hungriest—garden pests you'll ever encounter: the Tomato Hornworm. The good news? Once you know what to look for, they're surprisingly easy to find. 𝐖𝐡𝐚𝐭 𝐈𝐬 𝐚 𝐓𝐨𝐦𝐚𝐭𝐨 𝐇𝐨𝐫𝐧𝐰𝐨𝐫𝐦? Tomato hornworms are the larval stage of a large moth called the sphinx or hawk moth. These bright green caterpillars can grow up to 4 inches long, making them one of the biggest caterpillars found in vegetable gardens. Despite their size, their green color provides incredible camouflage. The black "horn" on their tail may look intimidating, but it's harmless to people and pets. 𝐖𝐡𝐚𝐭 𝐃𝐨 𝐓𝐡𝐞𝐲 𝐋𝐢𝐤𝐞 𝐭𝐨 𝐄𝐚𝐭? Hornworms are especially fond of plants in the nightshade family, including: 🍅 Tomatoes 🌶️ Peppers 🍆 Eggplants 🥔 Potatoes While tomatoes are their favorite meal, they'll happily munch on several related plants if given the chance. 𝐇𝐨𝐰 𝐭𝐨 𝐒𝐩𝐨𝐭 𝐓𝐡𝐞𝐦 Look for: ✔ Large sections of missing leaves ✔ Bare stems with little foliage ✔ Dark green or black droppings (frass) on leaves or around the base of the plant ✔ Large green caterpillars blending into stems ✔ Chewed green tomatoes If you see piles of droppings but can't find the caterpillar, look directly above them—they're often hiding in plain sight. 𝐖𝐡𝐲 𝐓𝐡𝐞𝐲'𝐫𝐞 𝐚 𝐏𝐫𝐨𝐛𝐥𝐞𝐦 One hornworm can eat an astonishing amount of foliage in just a few days. Several hornworms feeding together can: • Strip large branches • Slow fruit production • Damage developing tomatoes • Stress otherwise healthy plants Young tomato plants are especially vulnerable. 𝐇𝐨𝐰 𝐭𝐨 𝐆𝐞𝐭 𝐑𝐢𝐝 𝐨𝐟 𝐓𝐡𝐞𝐦 Fortunately, hornworms are one of the easier pests to control. ✔ Hand-pick caterpillars and remove them from your plants. ✔ Drop them into a bucket of soapy water. ✔ Inspect plants every evening or early morning when they're easier to spot.
