Silky webs wrapped around branch tips across the Upstate this fall are the work of fall webworm caterpillars.
Pecans, persimmons, sourwoods, sweetgums, and black walnuts are common hosts in Greenville and Spartanburg County. The caterpillars feed on the leaves inside the web and expand it as they go. On established, healthy trees the damage is usually cosmetic, because feeding happens late in the growing season.
Nests within safe reach can be pruned out or opened so birds and beneficial insects can reach the caterpillars. Burning nests or working from a ladder with a pole saw is not safe. Young trees that are heavily infested year after year, or trees showing other signs of decline, benefit from an assessment by a Certified Arborist.
Premier Tree Care has served Greenville, Greer, Taylors, and the Upstate since 2008.
