Blue Spruce - Sawfly and Multiple Leader Questions

Hi all. I've got a couple dozen blue spruce trees 2nd and 3rd growing seasons, 6-8 ft and been hand-picking sawfly larvae off my trees for the second straight year. It's getting to be too time consuming so next season I will spray. I was wondering if Carbaryl is OK to use on them and is effective?

Also, I have some trees with multiple leaders. Can I prune them now of should I wait until next late winter/early spring? I am in Zone 4B/5A. Thanks.
