Subterranean Termites and Hawthorne's 1950s Slab Homes
Why slab homes are vulnerable
Block after block of Hawthorne is 1950s and 1960s slab-on-grade tract housing, the home built on a concrete slab poured right on the ground. Subterranean termites live in the soil and need that soil contact. They build pencil-width mud tubes up from the ground through slab cracks, expansion joints, and plumbing penetrations to reach the wood framing above.
Because the damage starts hidden inside walls and under floors, most homeowners have no idea until they spot mud tubes, a swarm, or soft wood. Left alone, subterranean termites are the most destructive wood pest in California.
Signs to watch for
The clearest sign is mud tubes, thin tan-brown tubes running up the foundation, garage slab, or plumbing. In spring you may see a swarm of dark winged termites, or find their discarded wings on windowsills. Wood that sounds hollow when tapped or a floor that feels soft can mean interior damage.
Don't confuse them with drywood termites, which need no soil, live inside the wood itself, and drop little six-sided frass pellets below eaves and trim. The older stucco homes here get those too, and the two are treated differently.
How they're treated
Subterranean termites are handled with a liquid termiticide soil barrier: the soil around the foundation and slab is trenched and treated so termites hit a continuous treated zone, often paired with in-ground bait stations. This does not require tenting.
The move is a prompt inspection. A local exterminator confirms which termite you have and how far it has spread, then treats the colony and flags the moisture and wood-to-soil contact that invited them in. Catching it early is far cheaper than repairing structural damage later.
