What chemical should I use to kill Bagworms on my Dwarf Alberta Spruces ?

[Grassman]

I hand picked all the adult bagworms off my Dwarf Alberta Spruces last fall, but they are still covered with newly hatched bagworms that are killing them. I know I need to spray now, but what is the best Chemical to use to do this?

i didn't see any bagworms on your kubota, maybe i missed it.

i use bayer products on my trees.

ain't gotta mix it heavy, they're easy to kill.

mix light, spray often.

BT or Orthene have worked well for me.

Thanks......now do I trim out the dead parts of my spruce ?

Thank you very much......My Dwarf Alberta spruces are about 7 feet tall.....I have 8 of them.......and one is about 40 % defoliated. After I make sure those parts are not comming back, should I cut the limbs that are dead off at the trunk ?

Well...

Considering dwarf albertas are short, try hand picking. I hand pick bagworms with great sucess. I even get them on my crabapples, but none on my needle-leaf trees, must have built a resistance to my five fingers, But handpicking is a better option then pesticides.
