San Diego’s beautiful, mild climate is one of the reasons so many homeowners love calling it home. Unfortunately, termites love it too. Thanks to the region’s year-round temperate weather and seasonal humidity, termite infestations are not only common—they’re expected. The best way to protect your property from costly structural damage is to take proactive measures before termite season begins.
Learn why termite prevention matters in San Diego, when termite activity peaks, the most effective home protection strategies, and what to look for when inspecting your property. here’s some ways you can help keep your home termite-free.
Why Termite Prevention Matters in San Diego
While termites are a nationwide issue, San Diego homeowners face some unique challenges. The area is home to multiple termite species, including Western drywood termites and subterranean termites, both of which thrive in the region’s relatively warm and humid environment.
According to the National Pest Management Association, termites cause more than $5 billion in property damage each year in the United States. What makes termite damage particularly devastating is that it’s not typically covered by homeowners insurance. For San Diego residents, that means early detection and prevention isn’t just smart—it’s essential.
When Is Termite Season in San Diego?
San Diego’s termite season tends to ramp up in the spring and summer, typically from March through August, when temperatures rise and moisture levels increase. During this time, termite colonies produce “swarmers”—winged reproductive termites that leave the nest in search of new places to establish colonies.
Drywood termites tend to swarm on warm, dry days, especially after a spike in temperature or a rare rainstorm. Subterranean termites prefer moist soil and often swarm in the spring, following periods of rainfall. If you’re seeing flying insects indoors or discarded wings near windowsills, it could be an early sign that your home is already under attack.
Top 7 Termite Prevention Tips for Homeowners
1. Eliminate Moisture Sources Around the Home
Termites are attracted to moisture. Leaky pipes, standing water, and poor drainage around your foundation can create an ideal habitat for subterranean termites.
- Repair leaking faucets, roofs, and plumbing as soon as possible.
- Ensure gutters and downspouts direct water away from your foundation.
- Ventilate crawlspaces and attics to reduce humidity.
2. Seal Cracks and Entry Points
Prevent termites from getting in by sealing up potential access points:
- Caulk cracks around windows, doors, and foundation walls.
- Replace weatherstripping and repair damaged screens or vents.
- Use mesh screens to cover attic and crawlspace vents.
3. Keep Wood Away from the Foundation
Termites feed on cellulose, which is found in wood and wood-based materials. Keeping these materials away from your home’s foundation reduces your risk of infestation.
- Store firewood at least 20 feet from your home.
- Avoid using wood mulch directly against the exterior walls—opt for alternatives like gravel or rubber mulch.
- Ensure decks, fences, and sheds are made from treated lumber and have no ground contact.
4. Schedule Regular Termite Inspections
Annual termite inspections by a licensed termite control company are one of the most effective ways to prevent infestations. Professionals can detect early signs of termite activity that are easy for homeowners to overlook.
Inspections often include:
- A full visual review of your home’s interior, exterior, attic, and crawlspace
- Moisture readings
- Identification of vulnerable areas
Early detection can save thousands in potential repair costs.
5. Use Termite-Resistant Materials
If you’re remodeling or building, consider using materials that are less prone to termite damage. Pressure-treated wood, metal framing, and concrete or brick foundations are all excellent choices. These materials make it harder for termites to establish colonies and often deter them altogether.
6. Maintain Landscaping Around Your Home
Your yard plays a role in termite prevention too. Overgrown or poorly managed landscaping can trap moisture or provide easy pathways for termites.
- Keep bushes and tree branches trimmed away from the home.
- Remove stumps, dead wood, and leaf debris.
- Avoid excessive watering near your foundation or around wood structures.
7. Treat High-Risk Areas with Preventive Solutions
Even if you haven’t had termite issues in the past, proactively treating vulnerable areas can add an extra layer of protection.
- Apply borate treatments to exposed wood in attics, crawlspaces, and under decks.
- Use termiticide barriers or bait systems around your home’s perimeter.
- Install vapor barriers in crawlspaces to reduce moisture.
Common Signs of a Termite Infestation
Despite your best efforts, termites can still sometimes find their way in. Recognizing the early warning signs is critical for stopping them before serious damage occurs.
- Discarded Wings: Especially near windowsills, light fixtures, or entry points
- Mud Tubes: Thin tunnels of mud on exterior walls or foundation, used by subterranean termites
- Hollow-Sounding Wood: Knock on beams, baseboards, or walls—if they sound hollow, termites may be inside
- Blistered or Bubbling Paint: Termites tunneling underneath can cause the surface to appear warped
- Droppings (Frass): Drywood termites often leave behind small, pellet-like droppings
When to Call a Termite Control Professional
If you notice any of the signs listed above—or if you simply want peace of mind during termite season—it’s time to contact a termite control expert. A professional will conduct a thorough inspection, identify the termite species involved, recommend a custom treatment plan, and offer long-term solutions, such as bait stations or preventive barriers.
Don’t wait until you’re dealing with expensive repairs. An ounce of prevention truly is worth a pound of cure when it comes to termites.
