星加坡亦有網民用「蝗蟲」來形容來自中國嘅移民，主要批評佢哋普遍自大無禮、唔尊重當地文化、唔遵守當地秩序、同本地人爭福利同工作機會等等。尤其是喺「中國留學生批評星加坡狗比人多」、「中國富豪駕駛法拉利肇事」等事件發生之後，星加坡網民廣泛使用蝗蟲論。
Some netizens in Singapore also used the term "locust" to describe immigrants from China, mainly criticizing them for their general arrogance, lack of respect for local culture, failure to follow local order, and competition with locals for welfare and job opportunities. Especially after the incidents of "Chinese students criticizing Singapore for having more dogs than people" and "Chinese tycoons driving Ferraris causing accidents", Singapore netizens widely used the locust theory.
