Answer: I wish there were an easy solution, but trapping or poisons are about your only real methods of control. I checked with WSU cooperative extension and they have a publication, but there's a charge to download. So, I went to the UC Davis website and found a publication with lots of information, most of which parallels WSU's recommendations. So, here's the UC Davis website: http://www.ipm.ucdavis.edu/PMG/PESTNOTES/pn7433.html
Hope you find the information helpful!
