Instructions
Identify the nests silk worms have made. They have a silky, almost spider web look to them, but they are thicker. The longer the nests are allowed to live, the thicker and more numerous they become. The nests can stretch over numerous branches and encompass large amounts of leaves.
Sheer the branches that webs built on. Also, remove leaves that have silk worm larvae on them. You can also tear down the nests already created. Knocking them out of branches with a broom or large stick is the best method. Place all the branches, nests and infected leaves in a trash bag and dispose of properly.
Break open nests in trees to eliminate silk worm infestations naturally. This allows bugs and birds the opportunity to eat them. Once torn open, insecticides can be used to eliminate remaining silk worms. Insecticides do not work if they cannot penetrate the webs created by silk worms. Insecticides that contain carbaryl, chlorpyrifos, diazinon, malathion and tebufenozide as an active ingredient work. Spray these insecticides carefully with a nose-end sprayer to be effective.
Call a professional exterminator to spray for silk worms in locations that are too high to reach safely.
