Why does tick activity decline during the late summer and fall?

Answer

The weather conditions become too dry

Ticks are arachnids that rely heavily on humidity to survive and thrive. In the Pacific Northwest, tick activity is highest during the spring and early summer when the environment is lush and moist. As the weather patterns shift to drier conditions in the late summer and fall, the lack of sufficient humidity causes tick activity to drop significantly.
