Crawl Space, Garage, Roofline — a Daly City House Has Three Pressure Points

Read the Daly City tract house as a system and the pattern gets simple. Under the floor, bare damp soil in a fog-belt crawl space supports subterranean and dampwood termites, wood-decay fungi and Oriental cockroaches. In the middle, the attached garage below the living space gives black widows their preferred dark harborage and gives Argentine ants a slab full of joints to climb. Above, the low-slope roof and its vents are where roof rats get in. Three zones account for most of the calls.

Narrow lot lines multiply all of it. Houses in Westlake and Serramonte sit a few feet apart, often attached or nearly so, so a neighbor's untreated ant supercolony, an open eave two doors down, or a rat run along a shared fence becomes your problem. Treating one address in isolation does less here than it would on a quarter-acre lot. The workable approach is sealing your own structure properly and keeping the exterior current, because the lot next door is not yours to control.

What is different about this climate is that no season saves you. Roughly ten degrees separate the average July high from the average January high, so populations carry over instead of dying back and restarting. The two events that genuinely move pests are the first rains of October and November and the soil dry-down of late summer, and both push activity indoors. A house that is sealed and dry takes both without much drama.
