When Drywood Galleries Turn Up in Three Rooms of a Downtown Hayward House, Spot Work Stops Paying

Whether a house needs a tent comes down to distribution, not to how severe any single gallery is. Western drywood termites (Incisitermes minor) live entirely inside the wood, so one colony can sit in a rafter for years while a second works a window header on the far side of the house. When our inspection finds evidence in separate, unconnected members — and especially when some of it sits in framing nobody can reach — treating each accessible spot leaves the rest alive. Vikane gas reaches every void in the structure at once, which is the only thing that does.

Hayward's older housing is where that adds up. Downtown, Upper B Street and the Craftsman and Victorian pockets nearby predate the tract waves by decades, and the hillside blocks climbing toward Hayward Highland stay warm enough — summer highs in the mid-to-high 70s, mild winters — that colonies never take a hard seasonal break. The 1950s and 1960s tract houses reach the same point eventually. They have simply had fewer years to get there.

Tenting a Hayward house has practical constraints too. Lot lines on the older downtown blocks are tight, mature street trees hang over rooflines, and shared fences and near-attached neighboring structures change how the tarps seal and who has to be notified. We work all of that out before a date goes on the calendar, not on the morning of.
