The Central Valley's dry summers and mild winters suit termites, and Stockton homeowners deal with two main types. Many are surprised to learn that wood-destroying insects can thrive in a city that sees little rainfall for half the year, but irrigation, fog and plumbing leaks give them what they need.
Drywood versus subterranean
Drywood termites live entirely in the wood they eat, such as attic rafters, eaves, window frames and wooden furniture. They require no connection to the soil, and swarm on warm days, often in late summer or fall. Their pellets, which look like tiny six-sided grains, drop from kick-out holes. Western subterranean termites nest in soil and travel through mud tubes; they thrive near leaks, irrigated planters and damp slabs. Dampwood termites occur in very wet wood. A proper inspection identifies which are present.
Why Stockton homes are exposed
Stucco homes with wood framing dominate the city. Attic vents, fascia gaps and soffits provide entry for drywood swarmers, while plumbing penetrations and cracks in slabs and stem walls give subterranean termites a path. Older Victorian and craftsman houses in the Magnolia area have raised foundations with wood floor joists and original trim. Newer houses in Weston Ranch and Spanos Park are tightly built but still contain wood framing, and landscaping beds placed against walls can bridge the weep screed. Homes near the waterways deal with extra moisture, and winter tule fog keeps wood damp for long periods.
Signs to watch for
- Small piles of pellets on window sills, garage floors or beneath the eaves.
- Discarded wings near doors and windows after a warm day.
- Mud tubes on foundation walls, in crawl spaces or in the garage.
- Wood that sounds hollow, or paint that bubbles or ripples.
- Tiny round holes in wood trim, sometimes sealed with a plug.
Inspection and treatment options
Inspectors check the attic, crawl space, garage, exterior trim and landscaping with a flashlight, probe and moisture meter. Drywood termites can be treated locally if infestations are limited, or with whole-structure fumigation when activity is widespread, which requires leaving the house for a few days. Subterranean termites are controlled with soil treatments around the foundation, injections through slab edges or bait stations. Providers should supply a written report that notes areas of activity, damage and recommended treatment.
Protecting a Stockton property
- Keep soil, mulch and plants away from the stucco weep screed.
- Repair leaking pipes, gutters and irrigation lines quickly.
- Screen attic and foundation vents and seal gaps in fascia.
- Keep firewood and lumber off the ground and away from the house.
- Schedule regular inspections, especially before a sale or after a leak.
