Ticks in Central California: Know the Risk, Reduce the Exposure

Scientific name: Ixodes pacificus (western black-legged tick), Dermacentor occidentalis (Pacific Coast tick)

Central California's hills, redwood forests, coastal scrub, and grasslands host tick populations that are genuinely relevant to human and pet health. The western black-legged tick (Ixodes pacificus) — the primary vector for Lyme disease in California — is present in Santa Cruz and Monterey counties. Understanding tick habitat, personal protection, and when professional treatment of the yard environment is warranted is important for families in affected areas.

How to Identify Ticks

Size

Unfed adult: 2–4mm. Engorged female: up to 10mm. Nymph: 1–2mm (very difficult to see).

Color

Western black-legged tick: dark brown to black. Pacific Coast tick: brown with lighter leg markings.

Body Shape

Oval, flat when unfed. Balloon-shaped when engorged.

Distinctive Features

Eight legs (not six — arachnid, not insect). No wings. Mouth parts point forward (mouthparts used to anchor in skin). Small nymphal ticks are the size of a poppy seed.

Behavior & Lifecycle

Ticks quest — they climb to the tips of grass blades and low shrubs and extend their front legs to grasp passing hosts. They do not jump or fly. Ticks require a blood meal at each life stage (larva, nymph, adult). Lyme disease transmission by black-legged ticks typically requires 36–48 hours of attachment. The nymph stage (spring–summer) is the primary transmission stage because nymphs are tiny and often go unnoticed.

Ticks in Central California

Western black-legged tick populations are established in coastal woodlands and redwood forests throughout Santa Cruz County and in the brushy hills of Monterey County. Deer, lizards, and rodents are the primary host reservoirs. Properties adjacent to open space, chaparral, or forested areas in these counties carry meaningful tick encounter risk for outdoor activities. San Benito County's grasslands host Pacific Coast ticks.

Why This Matters Here

Ixodes pacificus is the vector for Borrelia burgdorferi (Lyme disease) in California. California has reported a growing number of Lyme disease cases annually, concentrated in the North Coast and Bay Area counties. The disease can cause serious long-term neurological and joint complications if untreated. Other tick-borne pathogens in California include Anaplasma and spotted fever group rickettsia.

How to Reduce Your Risk

The most cost-effective pest control is prevention. These steps reduce the likelihood of ticks problems — particularly important for properties in our service area where the conditions favor this species.

  • 01

    Use EPA-registered tick repellent (DEET or picaridin) on exposed skin for outdoor activities in tick habitat

  • 02

    Wear long sleeves and pants — tuck pants into socks in heavily infested areas

  • 03

    Check yourself, children, and pets thoroughly after outdoor activities in tick habitat areas

  • 04

    Remove any attached tick promptly with fine-tipped tweezers — grasp near the skin, steady upward pull

  • 05

    Keep lawn mowed and leaf litter removed — ticks concentrate at the border of maintained and unmaintained areas

  • 06

    Consider yard treatment if tick activity is high and the property borders tick-favorable habitat

When to Call a Professional

When ticks are being found on people or pets regularly from yard activity. When the property borders or is surrounded by tick habitat and outdoor use is limited by tick concerns. Professional yard treatment reduces tick populations in treated areas significantly but is most effective when combined with habitat modification.

Ticks FAQs

How do I remove a tick properly?

Use fine-tipped tweezers. Grasp the tick as close to the skin surface as possible. Pull upward with steady, even pressure — do not twist or jerk. Do not use petroleum jelly, nail polish, or heat — these methods can cause the tick to regurgitate, potentially increasing disease transmission risk. After removal, clean the bite area with rubbing alcohol. If a rash, fever, or flu-like symptoms develop in the following weeks, contact a physician.
