2. Description of the Related Art In recent years, bird damage such as fecal damage to crow nests and pigeons on elevated lines, station grounds, shrine grounds, and fold-roofed roofs of shrines, as well as garbage caused by stray cats Beast damage such as the eating and eating of animals has come to be noticed as a social problem. There are methods of exterminating these harmful birds and pests by means of drug killing and hunting killing, but both methods have many disadvantages as countermeasures considering animal welfare and ecosystem, and it is difficult to directly use them. In many cases Therefore, in consideration of various load factors such as harmful effects occurring at the time of extermination, the use of repellents is most effective in terms of a mild and peaceful means. However, the currently used repellents have a low effect, and their chemical properties have a drawback that the duration of the repellent effect is short. From the above points, developing repellents with excellent repellent effect and duration is not only an effective means for controlling harmful birds and pests, but also useful agriculture that can prevent damage to crops immediately before harvesting and immediately after sowing. A great effect is expected as a material or as an effective defense method against a wide range of harmful animals. The inventors of the present invention have completed the present invention by earnestly investigating a substance having a strong repellent activity. These substances are known but not known to have repellent activity.
