How to effectively drive wild boar?

I saw this on TV some time ago. Other people's methods on the Internet: 1. At about 9: 3 last Friday night, nearly ten wild boars quietly ran into the vegetable field of villager Wang Xingmin. Wang Xingmin's son, who was studying in the county, quietly put a tape recorder in the courtyard dam not far from the vegetable field, turned on the switch to turn the volume up to the maximum, and played the music of an American rock band. The wild boars rioted for a while and then ran away. Is the wild boar afraid to listen to this kind of music? The next day, Wang Xingmin did the same thing. The wild boar turned around and ran when he heard the music. On Tuesday, after learning that wild boar was afraid of listening to rock music, every household in the villagers dug out old tape recorders and collected rock music tapes to play in the fields all night. This week, none of the crops in the village were destroyed. Wildlife experts in Wuxi county believe that loud and harsh music does scare wild boars, but this effect may weaken with time: wild boars are not afraid after listening to it. He suggested that villagers set up patrol teams, or apply to the forestry department to kill a batch of wild boar without destroying the ecological balance. 2--------------------At about 2 o'clock in the morning, a big wild boar came down the hill and slowly approached a paddy field. Suddenly, there was a loud noise, and the cans fell to the ground, scaring the wild boar to fly back to the deep mountain. This is a scene that happened in Yalu Village, Xiangzhu Town, Yongkang City a few days ago. It turned out that this was a clever trick that farmer Lu Jinchong came up with to drive wild boar: on the side of the rice field, the cans were strung with iron wire, and the wild boar would run away in fear as soon as it touched the organ. In recent years, with the improvement of the ecological environment, the number of wild boar in Yongkang mountain area has doubled, and groups of pigs have ravaged crops, often causing farmers in mountainous areas to lose their crops. Because wild boar is listed as a provincial-level general protected animal, people are not allowed to kill it at will except for organizing hunting teams to kill it in the annual hunting season. To this end, Yongkang Daily launched Guangfa? Hero post? , deal with? Pig eight quit? The column, collect and introduce the coup of driving wild boar to benefit the mountain people to the society. In order not to harm wild boar, but also to protect crops from it, local farmers have come up with many ingenious ways to drive them away according to local conditions: tying old clothes into scarecrows, and scarecrows waving bamboo sticks in the wind; Install a recording horn in the field and play the driving sound of wow and wow all day long; The crops are hung with smelly pig bones, which makes the wild boar smell away. In Xiayuan Village, Xiangzhu Town, this city, there are thermos bottles hanging upside down all over the mountains. Farmer Li Yuangen said with a smile: When the moonlight, lights and other lights shine, the bottles refract dazzling reflected light, which is enough to shock the wild boar. In addition, the surface of the bottles is like a mirror, so that the wild boar can see that it is another big and deformed self on the mercury surface, and it is still a monster. For several nights, I hid aside and saw the wild boar run away in fear. The wild boar jar made in Yongxiang Village, Jiangnan Street is also very ingenious. It consists of three parts: a drain tank, a water receiver and an iron impactor. The drain tank injects water into the water receiver, and when the water receiver is full, it will turn over and hit the iron. Therefore, it will make a loud bang every few minutes, scaring the wild boar away.
