What is the primary method of control for subterranean termites?

The primary method of control for subterranean termites is chemical soil treatment. This approach involves applying insecticides to the soil around and under structures to create a barrier that prevents termites from accessing wood and other cellulose-based materials in buildings. This treatment is essential because subterranean termites live in the soil and can easily enter structures from below ground level.

Chemical soil treatments, also known as termiticides, are effective in protecting homes and other structures by eliminating termites that come into contact with the treated soil. These treatments can be applied as a preventive measure during construction or as a remedial measure if a termite infestation is discovered.

Baiting systems, while used to control termite populations, are typically more of a monitoring and population management strategy rather than a primary method of control. Physical barriers can help prevent subterranean termite access, but they are generally not as reliable on their own as chemical treatments. Heat treatment is more commonly used for drywood termites and does not specifically address subterranean termites, making chemical soil treatment the most effective primary method for dealing with these pests.
