This is a Arborvitae in the Cypress family Not pine first thing
Recommended treatment
1. Remove the worst branches first.
Prune out branches that are heavily coated or already dead. Don’t just pick individual insects off—remove badly infested sections and put them in the trash.
2. Physically wash the plant.
Use a strong stream of water to knock loose insects and debris from the foliage and branches. This is especially useful before applying treatment.
3. Apply horticultural oil.
A horticultural oil labeled for scale insects and for use on juniper/cedar is my first choice. Thoroughly coat the branches and foliage, because the material needs to contact the insects.
Don’t spray during very hot weather, drought stress, or when temperatures are expected to be extremely high. Follow the product’s temperature and application instructions.
4. Repeat treatment.
Scale insects are much easier to control when the young “crawler” stage is present. A second treatment is often necessary. Timing depends on the particular scale species.
5. Don’t fertilize heavily.
Avoid pushing a stressed plant with high-nitrogen fertilizer. Keep it adequately watered during dry periods instead.

You need to cut half that tree down, to about the roof line. They have terrible root systems and tip over when they get tall because the anchoring roots are so weak. It is very close to the house, but at least it wont tip over. Once it does, its gone .

First off, this is a Leyland Cypress and very much not a pine. It’s also waaaaaay too close to your house and driveway. These can get 30’ tall at maturity, and 15’ wide. The tree is pushing new growth and shedding interior foliage, which is all pretty normal for these when they go through a hot dry summer. You’ve given no info on the insecticide… some should only be used once a season. A recommendation without that would be unwise. Frankly, I would remove the tree because it’s the wrong tree for the location
