Fordham Tick Index

The Weekend Deer Tick Index

November 24 through 27, 2022


Tick Index

The Fordham Tick Index is an estimate of the risk of being bitten by a nymphal or adult deer tick. Both of these stages are active at this time of year, although the smaller nymph is responsible for many more cases of Lyme disease. This index measures risk relative to other times of year. For more information about preventing tick bites, controlling ticks, Lyme disease and other illnesses ticks carry, visit the Centers for Disease Control and Prevention.

The Fordham Tick Index is provided as a weekly public service by Fordham University and is based on both current and historical data from one site in Westchester County, N.Y. It is an estimate only. Actual risk may vary geographically. Therefore, always take precautions to prevent tick bites when outdoors.

Tick Fact of the Week

This is the final post for 2022: the Tick Index will resume in Spring 2023. The scent of a Christmas tree, one of its most appealing aspects, results from the essential oils found in its needles. Those same oils can kill blacklegged ticks. Another win-win situation. Happy holidays and best wishes for the new year.
