Fordham Tick Index

The Weekend Deer Tick Index

December 2 through 4:


Tick Index
Adult deer tick

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 update for the season. Although we are now officially heading into winter, and the new year is just weeks away, remember that ticks do quite well through most winters. And tick activity may be just a few warm days away, even in the heart of winter. If you live where ticks are common, continue to use common sense. Thanks and see you next spring.
