Georgia Southern has a tick research facility and has the United States National Tick Collection. Eat your heart out Harvard. What a distinction for the 'Boro. http://cosm.georgiasouthern.edu/usntc/ A buddy's farm was studied for tick population and the researcher put a quantity of dry ice on a blanket and dragged it through the woods and left it for hours and came back. The blanket was covered with ticks. They are attracted to CO2 which is the component of dry ice.
