Adult Deer Tick Density Chart: Beginning 2008

This interactive chart provides the average number of adult deer ticks, also known as blacklegged ticks, or by their scientific name <i>Ixodes scapularis</i>, collected per 1,000 meters sampled in the county (tick population density). Use the filters below to compare counties by year. <br /><br />Collection and testing take place across New York State (excluding New York City) from October to December, when adult deer ticks are most commonly seen. Tick population density can vary greatly within a very small area and within a county. These data should not be used to broadly predict disease risk for a county.These data should simply be used to educate people that there is a risk of coming in contact with ticks and tick-borne diseases.
