How do you prevent scale on house plants?

I have successfully treated scale on a ficus tree. Since scale seems to like
to go to the new, tender part of the plant, I cut it back. When the threat
of frost was past, I moved it outside and treated it systemically, twice.
When it was time to bring it back in the new growth had appeared and there
was no scale.
