Cut off branches infested with webworms and throw the branches in the trash. For trees that are not tall or overly infested, this a good method of removing the nests.

Spray the nests with Bacillus thuringiensis. These bacteria kill certain caterpillars without harming people, other insects or the environment. Open the nest with a stick and saturate the nest with the spray. Also, spray the area and leaves around the nest.
