We have a tree that is showing signs of emerging issues. Seems to be limited impact thus far. My wife thinks this may be a bagworm infestation. Online photos certainly seem to indicate this condition. See photo attached. Please advise if I can send additional photos as this link allows only one.
Several questions:
1) what kind of tree do we have (was planted before we purchased the home)
2) if it is bagworm, what is the recommended treatment ?
3) is this an infestation which can spread to other trees and shrubs ?
Any help will be appreciated.
Thanks

Your evergreen does have bagworms. The best time to treat is in the late spring to early summer. It is the larval stage that does the damage and that is when they are feeding. I have attached a link that provides you some great information along with several treatment options.
It is hard for me to tell from the photo, but it appears to be a type of fir or spruce.
Thank you for the extra photos. The color from the photos appears that the tree is green and not a blue-green(common color of most Douglas Firs). So, if your needles feel sharp - it is a type of spruce, If the needles feel soft, it is a type of fir tree. The best way to tell is by the cones.
