臭虫–第 2 级
21-07-2025 07:00
臭虫是一种叮咬人并吸人血的小昆虫。只有三种臭虫会叮咬人类。它们非常小而且扁平,因此可以藏在床上、家具或墙壁里。它们在夜间出来,利用热量和气味来寻找人类。
被臭虫叮咬时,您不会感觉到它们,但它们会导致皮肤发红、发痒。有些人则没有任何感觉。为了保持温暖和安全,臭虫会群居在一起。它们可以几个月不进食,有时甚至超过一年。人们经常会在不知情的情况下把它们装在包里或衣服里带回家。
很多人尝试过很多方法来阻止它们,比如烧床或使用植物。一种名为滴滴涕的强力喷雾剂曾有过一段时间的帮助,但后来被禁止使用。现在,臭虫又回来了,而且更难杀死。加热和吸尘仍然很有效。
