Multi-pronged approach, extra strong glue paper around all possible runs.
I prefer DIY, corn starch + water= super gloopy yet strong adhesive mix that they will eat, spread it across a wide bit of board and wait (light coating at edges to lure in then thick centre).
Then poison if you can get it (not sure what your licensing laws are, have always found this to be the most effective but least rewarding as they crawl off an die in an otherwise inaccessible bit and stink the place out)
