不好的消息是，Google说：
Most Japanese beetle traps contain two chemical attractants: a sex pheromone and a floral lure. Japanese beetles spend their days feeding in groups and mating, and the two chemical attractants in combination do an effective job of luring beetles in large numbers.
The big problem is that studies have shown that these pheromone lures attract far more beetles than they actually trap. In other words, when you hang a Japanese beetle trap in your yard, you are inviting every Japanese beetle in the neighborhood to your yard, but only a small percentage of these beetles will actually end up in the trap itself. The beetles that avoid the trap will now treat your well-manicured landscaping as a full-service buffet.

感觉这东西是捉虫喂鸡用的，而不是杀虫驱虫用的。
，偶读大学时也搞不清某种东西，还好当时一个农村来的男同学帮我解了围，我一直心存感激呢
