这是什么虫子

[Beefburger]

今年注意到屋子二楼外面的楼角围绕很多这样的虫子。很多邻居家也有。出现在天快黑的时候，这是什么虫子？JAP BEETLE? FURNITURE BEETLE？ 怎么杀他们或者让他们离开？

不知道

Looks like European chafer. It is a major turf pest and it feeds on many ornamental plants. Adults do not cause much damage, but larvae do. Larvae feed on roots of grass, many plants of ornamentals.

It is an introduced pest and it is a guarantee pest in Canada.

You can go to CT to buy some insecticides to spray them.

CT很多种的INSECTICIDE，就找能杀这种虫子的吗？是直接喷成虫就行吗？
有没办法杀土里的幼虫

这就是所谓的“grub”的成虫，在黄昏时候可以见到它们成群乱飞（绕着树， 房角什么的），个人基本无药可用， 再说你一个人用了也没有用，很快就会又飞来一群。从今年的成虫和雨水来看， 明年会大发。
