PROBLEM TO BE SOLVED: To provide a beast-preventing net system in which conventional plus and minus conductive net raw materials are alternately arranged to solve conventional problems, which is (1) a beast-preventing system ensuring effectiveness against harmful beasts such as monkeys, but further improves a beast-preventing effect, because a content related to a net raw material having a repellent is not disclosed, and which improves (2) the beast-preventing effect, because the disposition of a beast-preventing net, such as the stretching and/or spreading of the net, or the binding place and knitting of ropes are not disclosed. SOLUTION: This beast-preventing net system is characterized by alternately disposing plus and minus conductive net raw materials to knit a beast-preventing net, forming a standing portion and a creeping portion in the beast-preventing net, disposing the plus and minus conductive net raw materials in the standing portion, disposing a lightweight weight-containing rope at the end of the standing portion, and disposing a heavy weight-containing rope at the end of the creeping portion. Thus, an effective beast-preventing effect can be achieved. COPYRIGHT: (C)2006,JPO&NCIPI
