Tracking ticks in Connecticut

Deer ticks are becoming more prevalent in New England, as are cases of Lyme disease.

HARTFORD, Conn. — Connecticut residents who have hit the hiking trails or hung out in their backyards have likely run into ticks.

The tick that transmits Lyme disease is known as the deer tick.

Last year, the Connecticut Agricultural Experiment Station collected more than 4,000 ticks from submissions across the state and tested them for Lyme disease.  26% of those ticks came back positive for Lyme.

The relationship between weather and ticks is complex and research is ongoing. In some places, the climate is becoming less hospitable for ticks, but that’s not the case here in Connecticut. 

Temperature and humidity appear to be the main drivers. Deer ticks can survive longer in climates with higher humidity levels. In New England, summers are becoming both warmer and more humid. 

Anyone who find a tick on themselves or a pet can send it to the Connecticut Agricultural Experiment Station for testing. Click here for more information.
