Blacklegged Tick Surveillance

At a glance

The blacklegged tick (Ixodes scapularis) is widely distributed across the eastern United States. The greatest risk of being bitten exists in the spring, summer, and fall. However, adults may be out searching for a host any time winter temperatures are above freezing. Although all life stages bite humans, nymphs and adult females are more often reported on humans.
