St. Helena sits upvalley in the heart of Napa's wine country, a town of historic stone and wood buildings, Victorian and Craftsman homes, and blocks of vineyard on every side. That older housing stock is the defining pest factor. The aged redwood and old-growth lumber in the downtown buildings and historic homes is exactly what drywood termites colonize, flying in and setting up in attic framing, eaves, and trim, while the raised foundations and crawl spaces also give subterranean termites paths up from the soil.
The vineyards and oak woodland do the rest. Yellowjackets peak and turn aggressive around harvest, drawn to ripe grapes and outdoor dining, and roof rats and mice travel vine rows, creeks, and oak into attics and crawl spaces. Argentine ants trail indoors for water through the hot upvalley summer, and the western black widow settles into woodpiles, sheds, and crawl spaces.
An experienced local exterminator treats a St. Helena property for its age and setting: careful termite inspection of the historic wood with local or whole-structure options, harvest-season yellowjacket work, roofline and crawl-space rodent exclusion, and Argentine ant baiting with a treated perimeter.
