My large blue spruce is covered with bag worms on one side. It's also dead looking. Can anyone tell me how to control these and if the dead part of the tree will come back again?
Thanks!

I doubt that the dead part of the tree will come back but, you never know.
I'm not familiar with bag worms, but with tent caterpillars we just burnt them. Also, it would help to research to see what the predators of bag worms are and plant plants that will attract the predators. Also, research to find if there are any plants or other means of repelling the bag worms.
Anyone have any information on these guys?

Thanks Maine yes, BT is a bacterium spray that is commonly used in industrial organic gardening.
However, I would say that more research as to the population densities and localities of Bacillus thuringiensis need to be done before everyone goes out and starts using this bacterium everywhere.
Nature has existed for a long time without the introduction of foreign organisms to the mix and an introduction of a new organism can wreak havoc on functioning ecosystems.
I currently do not have the time to review the peer reviewed literature on this topic but if someone else does.... please do!
