How to get rid of termites in National City, CA
San Diego County's older wood-frame housing stock and warm, dry climate make it one of the more termite-active regions in the state. Drywood termites fly in during warm evenings, while subterranean termites build up from years of yard irrigation meeting foundation wood.
What you're dealing with in National City
Western drywood termites are the dominant species county-wide, with subterranean termites common in irrigated inland neighborhoods.
National City high-density rental stock along National City Boulevard and the older apartment buildings near 8th Street see persistent German cockroach and bed bug pressure from tenant turnover. Single-unit treatments do not solve building-wide problems, coordinated property-manager protocols do.
Why termites show up here
San Diego's core, La Mesa, and Lemon Grove hold some of the county's oldest housing stock, much of it original Douglas fir framing from the 1910s through the 1970s. That combination puts this region under the heaviest drywood termite pressure in San Diego County.
How to get rid of termites: step by step
- Inspect exposed wood for damage Tap wood trim, fence posts, and eaves with a screwdriver handle; hollow-sounding or crumbling wood is a warning sign worth a closer look.
- Check for discarded wings and pellets Sweep up any piles of small wings near windowsills or tiny pellet-like droppings under wood trim, both signs of an active colony.
- Reduce wood-to-soil contact Trim back mulch, firewood stacks, and wood fencing so they don't touch soil directly against the house foundation.
- Fix moisture sources near the foundation Redirect sprinklers and downspouts away from the foundation, since subterranean termites need consistent moisture to build mud tubes.
- Seal small cracks in stucco and foundation Caulk visible foundation cracks and gaps around utility penetrations to remove easy entry points.
When to call a pro in National City
Termites are not a DIY pest treatment. Once you find live termites, mud tubes, or damaged wood, the colony is already established and needs a licensed inspection to identify the species and the right treatment method.
