PURPOSE:To obtain a sheet-form rattrap which is easy to handle and does not pollute the environment, by providing isolated self-adhesive layers at regular intervals on one side of a long sheet, placing a release layer upon each self-adhesive layers in the direction perpendicular to the lengthwise direction thereof. CONSTITUTION:Isolated self-adhesive layers are provided at regular intervals on one side of a long sheet and a release layer is place upon each self-adhesive layer. The sheet is cut between the self-adhesive layers in the direction perpendicular to the lengthwise direction thereof. It is necessary that the isolated self-adhesive layers are provided at regular intervals from the viewpoint of the cutting of the long sheet. It is preferred that the self-adhesive layers are provided at intervals of 2cm or longer and are more than 1cm apart from the edge of the sheet to prevent the adhesive layers from being bonded to each other and causing pollution. A self-adhesive layer mainly composed of a rubber or a synthetic resin and contg. optionally a plasticizer, a solvent, etc., is used. It is preferred that a rubber sheet is used as a long sheet, because it can bit a narrow place or a curved place.
