Risk recalculates daily from the local forecast.
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
Los Altos is 53% natural land cover (52% forest, plus open and brushy areas) across its 6.54 sq mi, home to about 29,990 people. That makes it the 10th-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 Los Altos's local habitat, sets how high its daily score can climb when the weather and season allow.

Do I need tick control in Los Altos?
Today's risk in Los Altos is low (16/100), so there is no urgency. Quiet stretches are actually a good time to book: pros apply barrier treatments before activity climbs, and spring nymph season is when most Lyme transmission happens.

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 Los Altos?
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.
