Termite Control in Hayward, CA

Local Context

Two Termite Problems in One City: the Hills Above B Street and the Flats Below Hesperian

Hayward's east side is drywood country. The blocks around Upper B Street and downtown hold the city's oldest housing — Craftsman bungalows and early Victorians built long before the tract waves — and western drywood termites (Incisitermes minor) have had generations to work that framing. They live inside the wood and never touch soil. Mild summers in the 70s and winters that never freeze on the hillside streets below Walpert Ridge keep colonies feeding, and the late-season flights drop wings on a windowsill where nobody has looked in years.

The west side is a different animal. Ground between Hesperian Boulevard and the Eden Landing marshes sits low, drains slowly, and takes most of Hayward's 16 to 18 inches of annual rain between November and March. Subterranean termites (Reticulitermes) live in that soil and build shelter tubes up a stem wall or a pier block to reach framing. San Lorenzo Creek and the engineered channels that carry Sulphur Creek out through the Hayward Regional Shoreline keep the ground around them damp well past the last storm, so homes through Mt. Eden, Southgate and Longwood show tubing on foundations that stays active into summer.

In between sits the bulk of the city: tract houses built from the 1950s through the 1970s, with a median build year around 1972. Those homes are past 50 years old now, framed in standard-grade lumber, sitting on slabs or shallow crawl spaces under long low eaves. That age is why a Hayward termite inspection so rarely comes back empty. Which species we find depends on which side of the city you are on, and the treatment changes completely with it.
