Which method is considered effective for treating Drywood termites?

Applying heat or extreme cold is considered an effective method for treating Drywood termites because it targets the pests directly, disrupting their biological functions. Drywood termites are particularly susceptible to changes in temperature. By exposing the infested wooden structures to high temperatures (typically above 120°F for an extended period), it is possible to kill the termites at all life stages, including eggs, larvae, and adults.

Conversely, using pesticides alone may not effectively eliminate the entire colony, especially if the application is not thorough or if the termites are hidden within the wood. Building barriers can help prevent future infestations, but they do not address existing populations. Regular maintenance can catch potential issues early but will not remove an existing infestation. Thus, heat or extreme cold treatment is a targeted approach that disrupts the life cycle of Drywood termites effectively.
