Why Termites in San Diego Don’t Take a Holiday

Termites don’t follow the calendar. In San Diego, both subterranean and drywood termites remain active year-round, quietly damaging homes even during the holiday season. Early detection and professional treatment are essential to protect your property.

Even in December, termites are still hard at work. While most homeowners focus on holiday plans, these wood-destroying pests don’t slow down. In fact, San Diego’s mild climate allows subterranean and drywood termites to stay active, feeding on wood and creating hidden damage that can be expensive to repair.

​What This Blog Covers

Termites Don’t Take Winter Breaks

Subterranean Termites

As their name suggests, subterranean termites live in the soil. They love moisture and build mud tubes to access wood and other food sources, thereby avoiding exposure to air and subsequent drying. Since our winters are mild in San Diego, the soil doesn’t freeze; this allows them to continue their work in and around your home, often without notice, until damage becomes visible.

Drywood Termites

Unlike subterranean species, drywood termites infest the wood directly. Even during cooler months, they remain active inside your home, eating wood from the inside out. Furniture, decking, and structural beams are all vulnerable to damage.

Holiday Season Signs of Termite Activity

During the holidays, homeowners often bring out decorations, unwrap furniture, or set up holiday lights, activities that can reveal termite activity:

Noticing any of these signs should prompt immediate action to prevent further damage.
