Seasonal Tick Risks
The risk of contracting tick-borne disease from deer tick nymphs and adults varies by season. Although deer ticks are inactive in freezing temperatures, and survive well under the snow, they may be seeking a host (an animal to feed on) in bare sunny spots in midwinter.
Once the snow melts, the adults that failed to find a host in the fall will be out in substantial numbers throughout the spring, dying off in early summer. This is the same time that dog ticks are out, so it’s important to be able to tell the difference between the two. Dog ticks don’t transmit Lyme disease.
