Bradford Pear with worms

My Bradford pear has always been beautiful, it's about 10 years old now. All of a sudden I noticed some of the leaves are turning brown on certain branches. While checking out the tree we noticed their are worms inside the tree located at the joints. They obviously are killing my tree. How do I get rid of them and can we save the tree? Also there are small webs in all the joints where the worms are located.

It sounds like webworm damage if they are building webs in the branch angles of the tree. If possible remove the webs, doing this towards the evening hours when the caterpillars tend to be in the web and not feeding. Sprays work best when the worms are still small. Suggested sprays include Sevin, and Bacillus thuringiensis 'Kurstaki'. Spray the webs and areas around them. Follow label for mixing and applicataion directions.
