What is this bug killing my junipers

[FeltzE]

Something is killing my juniper bushes One of the bushes is looking like it's going to die, It does however have some new growth (a good sign)

I originally thought I got too close with some herbicide and injured the bush but my wife found these today.


The bush has alot of these cocoons on it I didn't see any bugs catapillers or other wildlife


You can see that one bush is almost brown and loosing its leaves.

I planted a privacy break of white cedar.  The buggers started chewing a couple of years later, during the drought.  I have about 50 trees.

So far, I've been using mechanical controls - picking by hand.  I get about 5000 or so a year.  I try to get them when they're small so there isn't too much damage.  But, you can't get them all.  I put them in a plastic bag and tie it shut.  

Next year I might go with an insecticide, since I'm not having any luck in locating Bt.  

The eastern red cedars seem to get only a few and aren't efffected that much.  I have seen eastern reds covered with them and still not have much defoliation.  

The fed says that low temperatures and parasites control them.  I haven't found this to be true.

Diaznion if it's still available...   Seems when something works, they ban it...

Thanks for the info, right now there is only a cpl of bushes infested, Looks like we go picking bugs then follow with an insectacide in the spring for the ones we miss.
