How Do Box Tree Caterpillar Nematodes Work? Box tree caterpillar nematodes contain Steinernema nematodes, which target and kill box tree caterpillars. These nematodes reproduce inside the caterpillars, releasing more nematodes into the environment to continue the pest control process. When Is the Best Time to Apply Box Tree Caterpillar Nematodes? The optimal time to apply box tree caterpillar nematodes is during the caterpillars' active period, from March to October. Ensure the soil temperature is above 10 degrees Celsius and avoid extreme temperatures for effective application. What Are the Signs of a Box Tree Caterpillar Infestation? Signs of a box tree caterpillar infestation include defoliation, webbing, and visible caterpillars on box plants. Initially, caterpillars appear green and yellow with blackheads, later maturing into caterpillars with black and white stripes. Plants may also exhibit patches of dieback.
