The European subterranean termite Reticulitermes grassei Clément, 1978, has been an important pest in Palenciana, a locality in the southern province of Cordoba (Spain) for a long time. The different stages of the pest elimination process have been studied and are presented here. Firstly, a through inspection of all town dwellings was conducted in order to determine a theoretical affected area of ca 65,836 m2. That area was monitored by installation of 2200 baiting (monitoring) devices provided by Dow AgroSciences Iberica S.A. (Dow). The inspections conducted during the pre-treatment and treatment phases, have allowed us to estimate the real extent of the pest (58,881 m2). Particular attention was given to the distribution of termites in Palenciana dwellings in houses where the level of destruction of the wooden beams might have increased significantly the risk of collapse.
