California’s Termite Challenge


California’s warm climate makes it a hotspot for termite activity, costing homeowners billions in damage each year. With multiple species active in the state, knowing the types of termites in California and how to protect against them is critical. Among the most destructive are subterranean termites, which require specialized defense like subterranean termite barrier protection.


This guide will explore termite species in California, warning signs, prevention methods, and professional solutions. References from trusted agencies such as the California Structural Pest Control Board (SPCB), California Department of Pesticide Regulation (CDPR), and UC IPM are included to provide reliable insights. For local solutions, homeowners rely on Attack Pest Control.


1. Types of Termites Found in California

California is home to several termite species, each requiring a different treatment approach:

  • Subterranean termites: Live underground and attack homes through mud tubes.

  • Drywood termites: Infest dry wood in attics, furniture, and baseboards.

  • Dampwood termites: Thrive in wood exposed to high moisture or leaks.

According to UC IPM, subterranean termites cause the greatest structural damage statewide.

2. Why Subterranean Termites Are the Biggest Threat

Subterranean termites build colonies underground with millions of members. They consume wood 24/7 and create mud tubes for shelter. Because they attack from below, infestations are often hidden until damage is severe.

The CDPR regulates chemical treatments and soil barriers designed to stop these destructive pests.


3. Subterranean Termite Barrier Protection Explained

Barrier protection creates a treated zone around your home that termites cannot cross. Two main methods are used:

  • Soil-applied liquid barriers: Pesticides applied to soil around the foundation.

  • Bait stations: Strategically placed systems that lure and eliminate colonies.

The SPCB requires these services to be performed by licensed professionals to ensure effectiveness and safety.


4. Drywood Termites in California Homes

Drywood termites live inside wood and don’t need soil contact. They often infest:

  • Attics and rafters.

  • Furniture.

  • Baseboards and trim.

Localized treatments, fumigation, or heat treatments may be needed. For inspections, see termite inspection services.


5. Dampwood Termites and Moisture Problems

Dampwood termites prefer moist, decayed wood. They’re commonly found near roof leaks, plumbing problems, or crawlspaces with poor ventilation. Prevention involves moisture control, as emphasized by UC IPM.



6. Warning Signs of Termite Infestation

Look out for these indicators:

  • Mud tubes on foundations (subterranean).

  • Frass (droppings) resembling sawdust (drywood).

  • Hollow-sounding wood.

  • Discarded wings after swarms.

  • Sagging or blistered floors.


If you notice these, call Attack Pest Control immediately.

7. The Cost of Ignoring Termites

The CDPH warns that untreated infestations may lead to structural collapse, increased mold growth, and costly repairs. Our blog, Why Termite Damage Is Costly to Repair, explains why early action is far more affordable than restoration.


8. Real Estate and Termite Disclosure Laws in California

When buying or selling homes in California, termite inspections are standard. According to Expert DRE Compliance, sellers must disclose past or current infestations. Lenders often require clearance reports before closing.

Protect your property with a professional termite inspection.


9. Prevention Strategies Beyond Barriers

Beyond subterranean termite barrier protection, homeowners can reduce risks by:

  • Fixing leaks and improving ventilation.

  • Sealing cracks in foundations.

  • Keeping firewood away from structures.

  • Scheduling annual termite inspections.
