I am painting a house and I just took down all the plastic shutters. They've
been up for ~9 years and there's lots of paper wasps nest behind them. These
shutters are the kind that are individual slats not the solid piece kind.

Before I re-install them, is there a way to prevent or discourage them in
the future? Would attaching a piece of Tyvek or screen behind the shutters
prevent them from coming through?

A screen with openings small enough to stop the insects from getting in
would probably work. Just make sure the screen does not stop ventilation.
