I have a leafy tree that has been attacked by bagworms. The bark of the tree has been somewhat damaged. How can I get rid of the bagworms and save the tree?

Bagworms are difficult to control because they are often unnoticed until mature. If numbers are low, they can be picked off in late fall. Bacillus thuringiensis (Bt) is effective against bagworms if it is used against young larvae. Applications should be made at the end of June after all the eggs have hatched.
