Keep your family and pets safe from ticks in San Diego

San Diego County's coastal canyons, chaparral, and oak woodlands are ideal tick habitat. The western black-legged tick (Ixodes pacificus), the primary Lyme disease carrier on the West Coast, is widespread from Mission Trails and Black Mountain to Poway, Ramona, Alpine, and the backcountry. Pacific Coast ticks and brown dog ticks are common too, especially around homes with dogs that hike or visit off-leash parks.

Because winters here are mild and rains green up the hills from January through April, tick populations peak in late winter and spring, exactly when families spend more time outside. Adult ticks then quest into summer and fall, so risk is essentially year-round.

Ticks don't fly or jump. They climb onto vegetation and wait for a host to brush past. They arrive on rodents, rabbits, opossums, deer, coyotes, and outdoor cats, all of which routinely move through San Diego yards. Once a tick drops off, it can survive in moist leaf litter, mulch beds, ivy, ornamental grasses, and woodpiles for months while waiting for its next meal.

That's why focusing only on your dog or on the lawn misses the problem. Effective tick control means treating the transition zones where landscaped yard meets brush, fence line, or canyon.

Every visit starts with a walk of your property to identify high-risk zones: shaded perimeters, dog runs, play structures, woodpiles, and trail entry points. We then apply targeted residual treatments to the vegetation, mulch beds, and ground litter where ticks quest, plus the structural voids where brown dog ticks hide.

Because ticks have a multi-stage life cycle and eggs are protected from contact products, ongoing service is the only reliable way to keep populations down. Most San Diego properties do best on a monthly or every-other-month plan from spring through fall, with maintenance visits in winter.

Keep grass mowed short and trim back overgrown shrubs along fence lines. Move woodpiles off the ground and away from the house. Use bark mulch or gravel as a 3-foot buffer between lawn and any brushy edge — ticks rarely cross dry, sunny ground. Talk to your vet about year-round tick prevention for every dog and outdoor cat, and do a tick check on yourself, kids, and pets after any hike in San Diego open space.
