Collection Results

The collection results from the New York State Tick Blitz can now be viewed on an interactive map!

View Results Here!

Results have been grouped by zip code. Each dot on the map represents a zipcode where ticks were collected. The size of the dot represents how many ticks were collected in that zip code. Note: The dots are placed at the center of the zip code and do not show the locations where actual tick collections occurred.

You can zoom in and out on the map and click on each dot to see what ticks were found in each zip code across the Hudson Valley Region of New York!
