Vinegar will not rid your home of termites. In the case of subterranean termites, they are a naturally occurring pest in the environment. The key to termite control is to provide a barrier protecting your home from subterranean termite infestation. Vinegar will not do this. In the case of drywood termites, there would be no effective way to deliver vinegar inside the termite galleries, which are present inside the piece of wood. This is why gas, or fumigant, is the preferred method for drywood termites.
