What is a common method for controlling drywood termites?

Fumigation is a common method for controlling drywood termites because it involves a thorough treatment of the affected structure. In this process, the entire building is enclosed with gas-tight tarps, and a pesticide gas is introduced to penetrate all areas of the structure. This method is particularly effective for drywood termites, which often reside within wood structures and are difficult to reach with localized treatments. Fumigation ensures that the gas infiltrates wood and other potential termite habitats, effectively killing all life stages of the termites present inside.

Direct spraying may not be as effective for drywood termites, as these pests often live within the wood, making it hard for the spray to reach them. Trenching is more suitable for controlling subterranean termites, while baiting systems are generally used for various termite species but may not be the best choice for tackling drywood termites specifically, given their nesting and feeding habits.
