WHERE IS IT?
From Bay Area Lyme

From Bay Area Lyme
On the West Coast, the primary carrier is the Western blacklegged tick, or Ixodes pacificus, and its principal host the grey squirrel. (This differs from the East Coast where the Eastern Blacklegged tick, Ixodes scapularis, is the principal carrier and the white-footed mouse its primary host.). The Western blacklegged tick has been found in all but two California counties (56 in total) and infected ticks have been discovered in 42 counties.
In California, infected ticks have been found in 42 out of 58 counties.
