(Whitewater Valley)--An invasive tick species is starting to make an appearance in the Whitewater Valley that poses a threat to both people and pets.  It’s called an Asian longhorn tick, and it first appeared in the United States nine years ago.  But, last week, an Oxford vet treated a dog covered with them.  It’s the first time the tick has been confirmed in this area.  What’s unusual about them is that they can reproduce asexually, meaning they don’t have to mate to produce thousands of new ticks.
