Skyrocket Juniper insect/spider problem
So i had brought some skyrocket juniper from the nursery last week and today i finally have time to take a look at them and discover 2 of them have hundreds of white sac on the foliage. i don't know what kind of insect are they, they're brownish red in this stage. And couple of larger harder sac on the trunk and i suspect it is spider since i remove those bigger sac and then there's spider creeping around.
I would like to know how to treat these juniper from all these little creatures? Is there a good way to kill them now and repel them away?
i'm so frustrate to see the skyrocket are full of these insect.
