Abstract: A composition which causes adult boring bark beetles to discontinue boring, discontinue laying eggs and become disoriented and bore out of the tree or cease boring altogether and die is described. Additional tests have shown that beetles will not infest a tree which has been treated with the composition. Furthermore, the composition also causes beetle larvae to cease boring and die and also causes egg sacks to shrivel and die.

Abstract: An anchor is fastened into a drilled hole in substrate layer such as concrete by providing on an end portion of the anchor a surrounding layer of an adhesive of a character that it softens when heated and sets when it cools with a portion of the anchor exposed outside the hole. The exposed portion is heated by an inductive heating device in a heating cycle where the heating cycle is actuated by the operator switch but accurately controlled and limited to a single operation in the presence of the anchor by a control in the device in dependence on sensed environmental conditions and a measured size of the anchor.
