Termites In NorCal: Subterranean vs. Drywood And How To Spot The Difference

Living in Northern California offers many advantages: beautiful landscapes, thriving communities, and a climate that’s as unique as it is appealing. But that same climate is also pretty attractive to termites. And if you own a home here, that’s a problem worth knowing more about.

At Big Time Pest Control, we help homeowners and businesses protect what matters most. When it comes to termites, two main culprits cause trouble in our region: subterranean termites and drywood termites. Understanding the differences between these species is key to effective prevention and treatment.

In today's blog, we'll identify and compare the two species and explain how you can protect your property with expert termite control.

Understanding subterranean termites

Subterranean termites are the most common and destructive species in Northern California. They live in the soil and rely on moisture to survive, making crawl spaces, basements, and leaky areas around your home prime real estate.

Habitat:
They nest underground and use mud shelter tubes to travel safely between their colony and food sources (wood structures). These pencil-sized tubes can often be seen on foundations, walls, or crawl spaces.

Damage Patterns:
Subterranean termites eat from the inside out and work quietly. Because their colonies are large—sometimes numbering in the hundreds of thousands—they can cause extensive structural damage before you even realize you have a subterranean termite infestation.

Recognizing drywood termites

Unlike subterranean termites, drywood termites don’t need contact with soil. They live entirely within the wood they infest, which makes them harder to detect without a professional inspection.

Habitat:
They typically target dry, above-ground wood such as attic beams, furniture, wooden floors, and picture frames. You won’t see mud tubes with these termites—they simply don’t need them.

Damage Patterns:
Drywood termite colonies are smaller, so the damaged wood tends to be more localized, but it can still be costly if left untreated. Signs of activity include discarded wings, tiny holes in wood, and frass (termite droppings that look like fine sawdust or pepper).
