Common Termite Species in San Diego Area

San Diego is home to many termite species, each with its own traits and habits. The most common are the Western Drywood Termite (Incisitermes minor), Western Subterranean Termite (Reticulitermes hesperus), and Dampwood Termites. These include the Pacific Dampwood Termite (Zootermopsis angusticollis) and Nevada Dampwood Termite (Zootermopsis nevadensis).

Drywood Termites

The Western Drywood Termite (Incisitermes minor) is often seen in San Diego. They infest dry wood, like structural lumber and dead tree limbs. These termites can live in dry conditions for a long time.

They leave behind fecal pellets with six ridges and rounded ends. Their flying adults have dark brown bodies with smoky black wings. They swarm between July and October.

Subterranean Termites

The Western Subterranean Termite (Reticulitermes hesperus) is very destructive in California. They damage foundation and structural wood. They need moist places and stay connected to soil through tunnels.

The Formosan Subterranean Termite (Coptotermes formosanus) is rare in California but near San Diego. They swarm at dusk and are drawn to lights.

Dampwood Termites

Dampwood termites, like the Pacific Dampwood Termite (Zootermopsis angusticollis) and Nevada Dampwood Termite (Zootermopsis nevadensis), are found in coastal areas. The Pacific Dampwood Termite is the largest in California, almost one inch long. They live in moist wood in cool, humid areas.

They make fecal pellets without clear ridges. These termites are found in coastal areas of central and northern California.

Termite Species	Key Characteristics	Habitat
Western Drywood Termite (Incisitermes minor)	Low moisture requirement, distinctive fecal pellets, dark brown with smoky black wings	Dry, undecayed wood
Western Subterranean Termite (Reticulitermes hesperus)	Most destructive termite in California, require moist environments, soldiers have white bodies with pale yellow heads	Soil-based, maintain connection with soil
Formosan Subterranean Termite (Coptotermes formosanus)	Restricted to a small area near San Diego, swarm at dusk	Soil-based, limited to a small area in San Diego
Pacific Dampwood Termite (Zootermopsis angusticollis)	Largest termite species in California, up to one inch in length, produce rounded fecal pellets	Wood with high moisture content, cool, humid coastal areas
Nevada Dampwood Termite (Zootermopsis nevadensis)	Produce rounded fecal pellets, occur in higher, drier mountainous areas	Wood with high moisture content, higher, drier mountainous areas

Types of Termites and Their Behavior

Termites are fascinating social insects with a complex hierarchy and unique behaviors. Knowing the different types of termites and their traits is key to tackling infestations.

The subterranean termite is common in the United States. They are about 1/8 inch long and live in large underground colonies. These colonies can have up to 300,000 workers and build mud tunnels to find food, damaging wood structures.

The Formosan “super-termite” is found in warm places like Hawaii, California, and Florida. These termites are aggressive and can form huge colonies of up to 8 million. They pose a big threat to homes and buildings.

Arid-land subterranean termites are dark brown to black and 1/2 to 3/8 inch long. They are found in the Western U.S. and Midwest.
Drywood termites are common in states like North Carolina and California. They leave behind sand-like fecal pellets as a sign of infestation.
Desert drywood termites are yellow to light brown and about 1/2 inch long. They are found in dry climates like Arizona and Southeastern California.
Pacific dampwood termites thrive in moist wood. They are yellowish brown to reddish brown, with winged termites reaching almost an inch long.
Conehead termites have yellowish brown bodies and dark cone-shaped heads. They create wider and more extensive tunnels than subterranean species.

Termites rely on cellulose-containing materials for food. This can cause significant damage to wooden structures, including homes. Knowing the unique behaviors and traits of different termite types is essential for effective prevention and control.

“Termites have a complex social structure with different castes, including reproductives, soldiers, and workers. Most species swarm in late summer or fall, with some swarming in spring.”

Conclusion

Knowing about the different types of termites in San Diego is key for termite prevention, inspection, and treatment. Regular checks, good home care, and quick action can shield your property from termites. Treatments include spot treatments, fumigation, and other methods like heat or borate solutions.
