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 Dimas is 62% natural land cover (32% forest, plus open and brushy areas) across its 15.03 sq mi, home to about 33,105 people. That makes it the 24th-most wooded of the 141 towns in Los Angeles 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.
Los Angeles County reports about 0 Lyme cases per 100,000 people a year. That county-level disease pressure, combined with San Dimas's local habitat, sets how high its daily score can climb when the weather and season allow.
