CDC Report on Longhorned Ticks- November 2018

Where Are They Found in USA?

New Jersey, West Virginia, Virginia, Arkansas, North Carolina, New York, Pennsylvania, Maryland

Something to Consider- All of the longhorned ticks have been reported in states east of the Mississippi River, except for one in far northwestern part of Arkansas (as of 8/8/18). Somehow that tick made it across the Mississippi to get there. It is, therefore, very possible they can/will be found in all US states.
