go into your attic and pull the insulation out from around the vents that you have the problem with. Then take some standard insulation and fill in around the vents.
It can be blown in or more often it comes in large bagged bales and you cut and dump in the attic. The eaves are the portion of the roof that overhangs/extends past the wall. It's usually called a patio cover Orientation is how the home (or other structure) is positioned on the lot. They let in lots of light and are very attractive.
