I have made over 100 prints in the past two weeks and this is exactly what I am finding too.
I also notice dust more on the 35mm than 120 due to the greater degree of enlargement needed to attain the print.

- I store my negatives in archival and air tight (dust free) clam-shell binders (this helps a lot).
It is very very rare that I actually need to spot more than two to three spots in a print. I believe this is because I don't stir up any dust and because of how I store my negatives, for the most part.
The antistatic devices Max is referring to seem great too, but so far I haven't needed any of it.
