You might be surprised to learn that adult Western blacklegged ticks (Ixodes pacificus) are quite active in fall and early winter. These small ticks depend on moisture in their environment to keep from drying out. During hot, dry weather they are mostly inactive, spending lots of time in the soil layer and leaf litter where moisture levels are higher. In fall, cooler temperatures along with increased humidity and rainfall make it easier to come out and look for hosts! So while you’re outdoors enjoying a long awaited break from summer heat, remember to keep checking for ticks!
