Tick context for California
Western blacklegged ticks are the principal Lyme-disease vector on the Pacific Coast, but exposure and pathogen prevalence are not uniform. Coastal, woodland, chaparral, and inland habitats differ, so county-level context is essential.
Ticks to distinguish
- Western blacklegged tick
- Established along the Pacific Coast and the principal western tick associated with Lyme disease transmission.
- Pacific Coast tick
- Occurs in parts of the coastal West and can bite people.
- American dog tick / D. similis
- CDC distinguishes western D. similis from D. variabilis found mainly east of the Rockies.
Seasonal planning
Timing varies with latitude, rainfall, elevation, habitat, and life stage. Avoid importing an eastern U.S. tick calendar; consult current state and county information for the specific property.
Where to inspect first
- Woodland and chaparral edges
- Brushy trails and shaded leaf litter
- Wildlife corridors around landscaped properties
Property action checklist
- 1Use western species identification guidance
- 2Focus inspections on shade, brush, and edge habitat
- 3Treat county surveillance as more precise than a statewide average
