Ticks can live in cold places, but the diseases they transmit don’t propagate if the ticks are inactive for long enough in the winter. Ticks themselves are harmless, only the diseases they transmit are a problem
If they are talking about the Willamette Valley, there is a natural barrier preventing ticks from making it in ( cascade mountain range on all sides, Columbia River to the north )
Ticks will need to be introduced. It is bound to happen eventually but for now there are areas without ticks that latch onto humans.

if they can go that “far south”, i’m sure they are already where you are.
