Abstract: A method and apparatus for arresting structural termite infestation while eliminating the risk of poison exposure to occupants of the structure includes a power tool for drilling holes in wood members of a structure, implanting pellets of termite poison within the drilled holes, and sealing the holes. The tool includes a tubular body portion joined to a storage portion that stores a plurality of packages of pellets of termite poison. A platen assembly is secured to the storage portion and adapted to impinge on a wood member of a structure. The tubular body encloses a reversible drive motor connected through a gear train to rotate and translate the drill assembly reciprocally in a guideway. Cellulose balls impregnated with poison or insecticide or flagellacidal agents are grouped in loads, each load packaged and disposed in the tool parallel to the guideway, with a plug cork is disposed at the proximal end of each load.
