Subterranean termites cause the vast majority of termite damage in California. This is because their underground colonies can number up to several hundred thousand termites. This species must stay in close contact with the soil and its moisture to prevent their bodies from drying out.

Subterranean termites, like drywood and dampwood termites, have a caste system with a king, queen, soldiers, workers, nymphs and alates. The worker termites travel from the colony up into your home, feed on the wood, then return to the nest and pass nutrients to the remaining termites in the colony through their liquid excrement.

Subterranean Termite Alates (winged reproductive)

Subterranean Termite Detection

These termites can be detected by the shelter tubes they build to protect themselves from the elements or predators. More often, a home owner will discover a subterranean termite infestation during swarming season (usually spring or fall) when hundreds of winged alates leave the nest to start new colonies. These termite swarmers are attracted to light and often congregate at a window or multiple windows in your home.

Subterranean Termite Treatment

The most effective method in eliminating a subterranean termite infestation is by applying a non-repellent termiticide such as Termidor into the soil. This is a slow acting termiticide that allows the worker termites to pass through the material, take it to the nest, and transfer termidor throughout the entire colony. Omega Termite and Pest Control has been using termidor for 15 years and have had a great success in eliminating the entire subterranean termite colony in our customers’ homes.
