Bald Cypress Bald Cypress 1. I have two 15 feet tall bald Cypress in my yard. Someone told me that they are bagworms. Bagworms are on junipers and are in hard, conical-shaped bags or cocoons.
Webworms are in spider-web type bundles and are usually worse on pecans.
Cypress is not a preferred tree for them so that could explain the small webs. Look in the webs and see if you see small, fuzzy tan worms. If the worms are there you can use any insect larvae insecticide such as diazinon, malathion, orthene, or Bt-containing insecticides such as Dipel or Thuricide. Or you can physically remove the webs or carefully burn them out. Spraying then would obviously be a waste of time.
