Drywood vs Subterranean Termites: What Homeowners Should Know

When homeowners hear the word “termites,” they often imagine a single type of pest. But in reality, there are several distinct termite species in California, and each one behaves differently. Two of the most common are drywood termites and subterranean termites. While both can cause serious structural damage, the way they infest, feed, and spread are entirely different.

Drywood termites are often found in warmer, coastal climates and are unique in that they live entirely within the wood they consume. Unlike their subterranean counterparts, they don’t require soil contact or excessive moisture to survive. These termites create colonies inside dry, undecayed wood and can be found in roof rafters, furniture, framing, or hardwood floors. Because of their discrete behavior and smaller colony sizes, they are notoriously difficult to detect without a trained eye.

Subterranean termites, by contrast, require moisture and are typically found in the soil. They build mud tubes to travel from their underground colonies to above-ground wood sources. These termites can cause extensive damage very quickly, especially because their colonies are often larger and more aggressive. They typically invade through foundation cracks, plumbing entry points, or even expansion joints in concrete.

Understanding the differences between these two species is essential for selecting the appropriate treatment. Drywood termites are often managed through localized spot treatments or whole-structure fumigation, depending on the scope of the infestation. Subterranean termites are typically addressed using trench-and-treat liquid applications or baiting systems around the perimeter of the property.

At Proven Termite Solutions, we start with thorough inspections to identify the exact species involved. This ensures that every treatment is designed to address the specific habits and risk factors of the termite type, rather than applying a one-size-fits-all solution. Our technicians are trained in recognizing species-specific patterns and recommending the best approach based on the location, severity, and spread of the infestation.

Choosing the right treatment starts with understanding what you’re dealing with. By helping homeowners recognize the behavioral and structural differences between drywood and subterranean termites, Proven Termite Solutions ensures each client receives targeted, effective care based on real-world expertise.
