What's active right now

Summer heat and drought suppress tick questing across most of the West. Unlike the Northeast, midsummer is a LOW point out West: dry air and cured grass push ticks down to rehydrate. The exception is California chaparral, where Pacific Coast tick larvae and nymphs hold a late-summer bite risk.

Local tick habitat

San Jose is 42% natural land cover (20% forest, plus open and brushy areas) across its 177.94 sq mi, home to about 969,655 people. That makes it the 13th-most wooded of the 23 towns in Santa Clara County. The Rocky Mountain wood tick favors shrub-steppe, rocky slopes, and grassland-forest edges, while the western blacklegged tick lives in oak woodland and coastal brush: the more of that habitat a town has, the more places ticks can quest.

Santa Clara County reports about 1 Lyme cases per 100,000 people a year. That county-level disease pressure, combined with San Jose's local habitat, sets how high its daily score can climb when the weather and season allow.

It is the single most effective way to cut tick numbers in the part of the yard your family actually uses.

How much does tick control cost in San Jose?

Most homeowners pay about $100 to $200 per visit for professional tick spraying, or roughly $350 to $600 for a full season of barrier treatments, depending on lot size and how wooded the property is. Quotes are free, so it costs nothing to get a real number for your yard.
