California’s diverse climate is a haven for several termite species that can wreak havoc on homes and structures.
Termites are not just a nuisance; their ability to silently chew through wood, flooring, and even wallpaper can lead to extensive and expensive damage. Understanding the most common termite species found in California and how to identify, prevent, and treat infestations is critical for homeowners and business owners alike.
In this guide, we’ll explore:
- The most common termite species in California
- How to identify each species
- The risks they pose
- Tips for prevention
- When to seek professional help
1. Subterranean Termites: The Silent Invaders
Overview
Subterranean termites (Reticulitermes spp.) are the most common termite species in California, responsible for the majority of termite damage across the state. These termites build underground colonies and rely on moist soil for survival. They access wood structures through mud tubes, making them particularly dangerous due to their stealthy approach.
Subterranean Termites Identification
- Appearance: Worker termites are creamy-white and about 1/8 inch long. Soldiers have larger heads and prominent mandibles, while swarmers (reproductive termites) are dark brown to black with wings.
- Behavior: They create mud tubes to travel from the soil to wood, allowing them to remain hidden from view.
- Signs of Subterranean Termites Infestation: Look for pencil-thin mud tubes along foundations, damaged wood with a honeycomb-like interior, or discarded wings near windowsills.
Risks
Subterranean termites can cause structural damage by weakening the integrity of wooden supports, flooring, and walls.
Subterranean Termites Prevention Tips
- Reduce moisture around the foundation of your home by fixing leaks and ensuring proper drainage.
- Keep wood piles, mulch, and vegetation away from your home’s foundation.
- Install physical barriers, such as stainless steel mesh or sand, to deter termites.
2. Drywood Termites: The Independent Destroyers
Overview
Unlike subterranean termites, drywood termites (Incisitermes spp.) do not rely on soil for survival. They infest dry wood, often targeting exposed wood in attics, furniture, and structural timbers. They’re more common in coastal and southern parts of California, where the climate is warm and dry.
Drywood Termites Identification
- Appearance: Drywood termites are slightly larger than subterranean termites. Workers are light cream-colored, and swarmers have brown wings.
- Behavior: They live and feed within wood, leaving behind distinctive six-sided fecal pellets, known as frass.
- Signs of Infestation: Frass piles near wooden structures, hollow-sounding wood, and kick-out holes on surfaces.
Risks
Drywood termites can infest furniture, wooden beams, and other dry wood materials, leading to localized damage that can spread if untreated.
Drywood Termites Prevention Tips
- Seal cracks and crevices around doors, windows, and other openings to prevent swarmer entry.
- Use treated wood or paint to protect exposed wood.
- Regularly inspect attics and wooden furniture for signs of infestation.
3. Formosan Termites: The Aggressive Invaders
Overview
Formosan termites (Coptotermes formosanus) are an invasive species originally from Asia, but they have made their way to California, particularly in warmer southern areas. Known for their aggressive nature and large colony sizes, these termites can cause significant damage quickly.
Formosan Termites Identification
- Appearance: Similar in size to subterranean termites but with a slightly more yellowish tint. Swarmers have pale yellow-brown wings.
- Behavior: Formosan termites can build massive colonies that house millions of termites. They form mud tubes similar to subterranean termites.
- Signs of Infestation: Rapid structural damage, mud tubes, and discarded wings.
Risks
Due to their large colonies, Formosan termites can cause severe structural damage in a shorter time than other species.
Formosan Termites Identification Prevention Tips
- Eliminate moisture sources, especially around your home’s foundation.
- Inspect wooden structures regularly for mud tubes or other signs of infestation.
- Consider professional termite prevention systems, like baiting stations.
4. Dampwood Termites: The Moisture Lovers
Overview
Dampwood termites (Zootermopsis spp.) are commonly found in damp, decaying wood. While they are less likely to invade homes compared to subterranean or drywood termites, they can still pose a risk if wood in your structure has excessive moisture or decay.
Dampwood Termites Identification
- Appearance: Larger than other species, with workers measuring up to 3/4 inch long. They are pale brown with darker brown heads.
- Behavior: Dampwood termites infest wood with high moisture content and do not require contact with soil.
- Signs of Infestation: Soft, damp, and decayed wood with visible termite galleries or fecal pellets.
Risks
Dampwood termites are usually a sign of underlying moisture problems, which can compromise your home’s structure over time.
Dampwood Termites Prevention Tips
- Fix leaks in your roof, plumbing, and HVAC systems promptly.
- Replace or repair decayed wood in and around your home.
- Ensure proper ventilation in crawl spaces and attics.
Termite Prevention Tips for California Homeowners
While the specific steps may vary depending on the species, these general tips will help protect your home from termites:
- Regular Inspections: Schedule annual termite inspections with a professional pest control company.
- Moisture Control: Termites thrive in moist environments, so ensure proper drainage around your home.
- Wood Maintenance: Use treated wood for construction and repair damaged wood promptly.
- Professional Barriers: Install termite barriers and baiting systems around your property.

FAQs
What time of year are termites most active in California?
Termites are most active in California during the warmer months, especially spring and summer. This is when swarmers take flight to establish new colonies.
How do I know if I have termites in my home?
Look for mud tubes, hollow-sounding wood, discarded wings, frass (termite droppings), and damaged wood. If you notice any of these signs, call for a professional inspection immediately.
Can I treat termites myself?
While there are some DIY options like bait stations and sprays, termite infestations require professional treatment for effective elimination. DIY methods are often temporary and may not reach the colony’s heart.
By understanding the common termite species in California and taking proactive measures, you can protect your home from costly damage. For the best results, trust OPP to provide expert termite inspections and customized treatment plans.
