Can my dog still get fleas and ticks in the winter? - Countryside Veterinary Clinic

Definitely—mostly the ticks; depending on which tick it is and where you live, you will see Lyme ticks even in January, even in the snow. Certain ticks, deer ticks, brown dog ticks, lone star tick, they do live in different parts of the country, and they like different environments. So we will see them at different times of the year, but certainly in the winter.

And fleas, they like it up until the grass dies and it's wholly browned out, which takes a long time, not just one frost. And then they'll be back as soon as the weather gets warm and the grass starts to grow. So it’s a very long season for fleas and ticks, especially here in Maryland.
