Bakersfield is not a damp place, and that shapes the termite picture. Instead of the soil-dwelling species that dominate wetter regions, the Southern San Joaquin Valley's main termite is the western drywood termite, an insect that lives entirely in dry wood and needs very little moisture. Long hot summers actually suit it well, and swarms are an annual event in many neighborhoods.
The termites of the Valley
Western drywood termites establish colonies in attic framing, eaves, fascia boards, window and door frames, decks, patio covers and even wooden furniture, and they push out small six-sided pellets through tiny kick-out holes. Subterranean termites are present in some parts of Kern County, particularly around irrigated landscaping and leaky plumbing, where soil stays moist, and they build mud tubes. Dampwood termites are uncommon in this dry region but turn up in wood damaged by leaks. A good inspection pinpoints the species because treatment methods differ.
Why Bakersfield homes are susceptible
Large numbers of homes in Rosedale, Seven Oaks, Stockdale, Westchester and East Bakersfield have stucco exteriors on wood frames, with attic vents, exposed rafter tails and wood trim. Stucco cracks, vent openings and gaps around fascia let flying termites in. Backyard patio covers, pergolas and wood fences are often untreated and sit in direct sun, which makes them popular. Housing tracts are built closely together, and winged termites from one house can easily land on another roof. Older homes near downtown and Oildale have original wood siding, additions and porches that add more exposed lumber.
Warning signs
- Piles of tiny hard pellets, like fine sand or coffee grounds, on sills and in corners.
- Discarded translucent wings on window sills, usually after warm afternoons in fall.
- Wood that sounds hollow when tapped, or bubbling paint over trim.
- Small round holes about the size of a pinhead in wood surfaces.
- Mud tubes on exterior walls or in the garage, which suggest subterranean termites.
How inspection and treatment work
An inspector checks the attic, eaves, fascia, garage and exterior wood, looking for pellets, damaged wood and conditions that invite termites. Treatment for widespread drywood termites is often whole-structure fumigation, in which the home is tented, gas penetrates the framing and occupants stay out for a short period. For localized infestations, providers can inject foams or liquids directly into infested wood, or use heat or borate treatments. Subterranean activity is treated through soil applications or bait stations. After treatment, damaged lumber may need to be replaced by a carpenter. Inspection reports are a standard part of California real estate transactions.
Reducing termite risk
- Seal and paint exposed wood on eaves, fascia, trim and fences.
- Screen attic and foundation vents with fine metal mesh.
- Fix leaks and keep sprinklers from soaking siding or foundation.
- Keep firewood and scrap lumber off the property or far from the house.
- Inspect used wooden furniture before bringing it inside.

Termite questions in Bakersfield
When do drywood termites swarm?
Often in late summer and fall on warm days, though swarms can appear at other times of year.
Does a slab foundation prevent termites?
No. Slabs help against soil termites but drywood species fly to roofs and eaves directly.
Can I treat drywood termites with a spray?
Surface sprays do not reach colonies deep inside wood. Fumigation or targeted injection by a licensed provider is more effective.
How long does fumigation take?
Typically a few days from start to re-entry, with details given by the provider.
