准备一个空的汽水瓶,可以是用过的瓶子,或是把汽水倒出来。确保里面已经没有汽水,并用温水洗干净。

剪下瓶口。用剪刀的其中一个刀片在瓶子上戳一个洞,最好是瓶颈和瓶身连接处(靠近瓶子中间)。[2]

研究来源

戳了一个洞后,插入剪刀,开始沿着瓶子剪掉整个漏斗状的瓶颈。瓶子将被分成2个部分,一个是漏斗(顶端),一个是瓶身(底部)。
剪的时候,尽量让剪刀靠近瓶颈边缘。否则当你把漏斗倒转时,会无法固定住。
你也可以用一把锋利的刀剪掉顶端的漏斗状瓶颈,小心不要割到自己。如果是和小孩一起动手,最好还是用一把安全的剪刀。

将剪下来的漏斗翻过来,插入瓶子下半部分。只要剪的时候尽量靠近漏斗(瓶颈)边缘,把它塞进瓶子时,应该能固定在里面。

将2个被剪的部位连接起来。最简单、有效的方法是用订书钉将2个部分的边缘钉在一起。只要沿着瓶子钉3到4次(确保距离相等)。[3]

如果是和小孩一起动手,应该由成人负责将2个部分钉在一起。没有订书机?下面2个选择也很有效。
胶带也是不错的选择,但一定要选择防水胶带。沿着漏斗贴上3、4条胶带。
如果你想用强力胶或普通胶,也必须选择防水的胶粘剂。先在瓶身顶端内侧涂一层薄薄的胶粘剂,将漏斗倒过来,才塞进瓶子里。用手指将漏斗和瓶身压在一起。用手将它们贴在一起,直到胶粘剂变干。

调制融化的糖浆。将5汤匙糖倒入一个锅里。放在炉台上,把糖压平,让它均匀地铺在锅底。[4]

研究来源

倒入足够的水,直到水没过糖。用中大火慢慢加热,煮至沸腾。
将混合液拌匀。糖溶于热或温的自来水中时,只会变成糖水,将它煮沸却能制成糖浆。这是更浓缩的诱饵。等待一会儿,让糖浆从滚烫变成温热。

用勺子将糖浆舀到漏斗,让它流入瓶底。尝试把它滴在漏斗边缘,这样当苍蝇飞向漏斗时,从一开始就会被糖浆黏住。

使用另一种诱饵。你可以将几块苹果切片,让它们穿过漏斗底部,进入瓶底。放一块生肉,或是数汤匙陈酒也能起作用。加了糖或蜂蜜的水也行。

添加醋。如果你选择液态的诱饵,不妨添加数茶匙醋(最好是白醋),防止蜜蜂和其它不必要的昆虫接近捕蝇器。[5]

把瓶子放在有阳光的地方,帮助水果和肉类腐烂,这样苍蝇更有可能闻到诱饵。另外,液体也会蒸发,形成信息素,吸引苍蝇来到捕蝇器。在捕蝇器发挥作用时,你会对它的效果惊叹不已。

反复往瓶子里吹气。这么做可以提高捕蝇效果,因为昆虫会被热气和二氧化碳吸引。你也可以用两手搓瓶子,制造更多热气。

丢掉瓶子。当你看到苍蝇开始集聚在瓶内,就可以把它丢掉,制作新的捕蝇器。诱饵会慢慢失去作用,你需要再准备新的捕蝇器。要清空瓶子也不容易,因为苍蝇和诱饵会卡在漏斗里。你也不想用手处理死苍蝇吧。

剪下长长的布基胶带备用。胶带必须够长,足以围绕整个罐头。尽量不要碰到有粘性的那一侧,以免弄脏它们,导致捕蝇器无法起作用。

准备一个购物纸袋。最好是比较高的纸袋,因为你需要制作长长的粘蝇纸。别用塑料袋,因为粘稠的混合液无法黏在塑料上。

将纸袋剪成条状。用剪刀剪下2.5厘米宽、15厘米长的纸条。你需要约4到5张。剪好后,把它们平铺在桌子上。[17]

在纸条上戳一个洞。用剪刀或一把刀在纸条末端约2.5厘米处戳一个洞。每张纸条都要这么做。如果你有打孔机,也可以用它打洞。[18]

将一条绳子穿过小孔,然后系好。剪下至少15厘米长的绳子或金属丝。每张纸条都需要系一条绳子。将绳子或金属丝穿过洞,然后打一个结。

将纸条浸在混合液里。将每张纸条浸在混合液里,以便覆盖一层糖浆。之后铺在烤盘上,让它们变干。

把纸条挂起来。找一个铁钉或大头钉,将绳子挂起来。你可以将它们挂在靠近的地方,或是分散在家中几个地方。挂在靠近的地方会更有效。[20]

丢掉粘蝇纸。纸条粘满苍蝇后,就可以拿下来丢掉。如果出于某种原因,纸条不起作用,可能是所使用的糖浆不足。你可以制作新一批糖浆,再次把纸浸在里面,或是从头开始制作新的纸条。
