How insulate existing lathe and plaster exterior wall?

My home was built in 1924. The exterior is Stucco, lathe and plaster. I want to insulate and the only way I've read about is drilling many holes and trying to blow insulation in. Can I use expanding foam instead? The holes won't have to be as big and it seems like it would be more efficient.

Thank you!

Yes, there are companies that will install expanding foam insulation in your walls. The only caveat is if your home is wired with knob and tube wiring in the walls. The knob and tube should be abandoned and new NM wiring should be installed.

Just so you're using correct terms when/if you contact someone about this, you have lath and plaster walls, a lathe is a tool.
