Termites cause billions of dollars in structural damage each year, and California homes are especially at risk due to the warm climate and high moisture levels. These silent invaders often go undetected for months—or even years—before homeowners notice the damage. Prevention is the best defense against costly repairs and infestations.
In this guide, we’ll explore comprehensive termite prevention strategies, including DIY techniques and professional solutions to keep your home termite-free.
1. Keep Wood and Moisture Away from Your Home

Termites need two things to survive: wood and moisture. By eliminating these attractants around your home, you can significantly reduce the risk of infestation.
How Moisture Contributes to Termite Problems
Damp conditions create the perfect environment for subterranean termites, which are the most destructive species in California. Moisture allows these termites to build mud tubes and establish colonies near your foundation. Even drywood termites, which don’t require soil contact, are more likely to invade a home with high humidity.
What You Can Do:
- Store Firewood Away from Your Home – Keep firewood, lumber, and wooden debris at least 20 feet from your house and elevated off the ground. Firewood stacked against your home provides a direct path for termites to enter.
- Reduce Moisture Around Your Foundation – Fix leaky pipes, clean gutters regularly, and ensure downspouts direct water away from your home’s foundation. Standing water is an open invitation for termites.
- Use Mulch Sparingly – Mulch retains moisture and attracts termites. If you must use mulch for landscaping, keep it at least 12 inches away from your foundation and opt for termite-resistant options like gravel or rubber mulch.
- Ventilate Crawl Spaces & Attics – Proper ventilation helps reduce humidity, making these spaces less hospitable to termites. Installing a dehumidifier in damp areas can further discourage infestations.
2. Seal Entry Points and Cracks
Termites can enter your home through cracks as small as 1/32 of an inch. Even well-built homes have tiny gaps that can serve as entryways for these pests.
Common Entry Points for Termites:
- Foundation cracks
- Gaps around windows and doors
- Openings where utility lines enter the home
- Expansion joints in concrete slabs
- Roof and siding gaps
How to Seal Your Home:
- Inspect and Seal Cracks – Use a high-quality caulk or foam sealant to close gaps in your foundation, walls, and around pipes. Pay special attention to areas where wood meets concrete.
- Install Weather Stripping – Ensure doors and windows fit tightly to eliminate entry points. This also helps improve energy efficiency.
- Screen Vents and Openings – Cover attic vents, crawl spaces, and other openings with fine mesh screens to keep termites and other pests out.
3. Maintain Your Yard and Landscaping
A well-maintained yard doesn’t just enhance your home’s curb appeal—it also reduces the risk of termite infestations.
Why Landscaping Matters
Termites often start in outdoor wood sources (like fallen branches or dead trees) before making their way to your home. Overgrown plants and excessive moisture can create a bridge for termites to travel undetected.
Best Practices for Termite-Resistant Landscaping:
- Trim Trees and Shrubs – Keep tree branches and shrubs at least 12 inches away from your house. Overgrown plants create shaded, moist areas where termites thrive.
- Remove Dead Trees and Stumps – Decaying wood attracts termites. If you have tree stumps near your home, remove them to prevent colony formation.
- Improve Drainage – Ensure your yard slopes away from your home’s foundation. Standing water increases the risk of termite activity.
- Use Termite-Resistant Mulch – Cypress, cedar, and rubber mulch are less attractive to termites than standard wood mulch.
4. Use Termite-Resistant Materials
When building or renovating, using termite-resistant materials can provide long-term protection against infestations.
Best Materials for Termite Prevention:
- Pressure-Treated Wood – Treated with chemicals that repel termites, this wood is a great option for decks, fences, and structural elements.
- Composite or Metal Materials – Instead of traditional wood, consider composite decking, metal framing, or fiber-cement siding, which are naturally termite-resistant.
- Concrete Barriers – If you’re building a new home, concrete foundations and barriers can block termites from entering.
Additional Protective Measures:
- Apply borate wood treatments before installing wooden structures.
- Use metal termite shields between the foundation and wooden framing to block access.
5. Schedule Regular Termite Inspections
Even with strong prevention methods, termites can still invade. Regular inspections help detect early signs of termite infestation before they cause significant damage.
How Often Should You Get Inspected?
- Annually – A yearly termite inspection is recommended for all homes, even if you don’t see any signs of termites.
- After Heavy Rain or Construction – Moisture and soil disturbances from renovations can attract termites, so schedule an inspection after these events.
Signs of Termites to Watch For:
- Mud tubes along walls or foundation
- Hollow-sounding wood
- Discarded wings near windows or doors
- Small holes in drywall with fine dust (frass)
- Warped doors and windows that no longer close properly
6. Consider Preventative Termite Treatments

In addition to DIY prevention, professional termite treatments provide long-lasting protection.
Types of Termite Prevention Treatments:
- Soil Treatments – Liquid termiticides are applied around the foundation to create a barrier that kills termites on contact.
- Bait Stations – Baiting systems attract termites and eliminate colonies before they can cause damage.
- Wood Treatments – Preventative treatments using borates can protect exposed wood from termites.
Are Preventative Treatments Worth It?
Yes! Investing in termite prevention is much cheaper than repairing termite damage. Many pest control companies offer warrantied protection plans, giving homeowners peace of mind.
