Tree caterpillar nests look like silken bags hanging in branches. You can either remove each nest by cutting the silken string at its top and then dropping the entire nest in soapy water or tear the nest open with a stick and let birds prey on the caterpillars inside. The pests feed during the day when the sun shines.
