Suspend SC is labeled for Gypsy moth larvae, but we would recommend a product like Monterey Garden Insect Spray. Using an insect spray containing Spinosad is the most effective way to treat for this type of caterpillar. When sprayed on the foliage, this products works by poisoning the caterpillars feeding on the leaves.
