在一个大碗里装满醋。不要倒满了，因为您要把毛巾浸在里面。

将毛巾放入碗中，浸泡至少5分钟。布需要浸透，否则虫子会从布下面爬出来并逃跑。

将醋浸湿的毛巾盖在房屋的每个排水管上。应该在可以打开一些窗户的时候这样做，因为房屋会散发出强烈的醋味。

在毛巾上倒至少一杯醋。如果可能，请避免使用已处理数小时的水槽。如果需要使用其中一个水槽，请立即更换毛巾，并在管道中倒入更多的醋，以确保水不会稀释处理液。

几个小时后，取下毛巾。不要冲洗水槽，而要等到正常使用后才可以将醋分散。这种处理方法将杀死一些虫子，并将其他虫子驱赶到房屋外或已经被杀虫者处理过的地方。

在家里还可以采取一些现有的措施来消灭蟑螂，蟑螂很喜欢洗衣粉的香味，只要把洗衣粉撒在地面上，蟑螂闻到了会吃洗衣粉死去，这种除蟑螂的方法很高效，直接又简单，也不会有什么副作用。

这是个非常方便的法子，不会影响到你的居家生活，还能有效的把蟑螂消灭掉。

Fill a large bowl with vinegar. Don't fill it up, because you have to soak the towel in it.

Put the towel into a bowl and soak for at least 5 minutes. The cloth needs to be soaked, or the insects will climb out from under the cloth and escape.

Put a towel soaked in vinegar on each drain pipe of the house. This should be done when some windows can be opened, because the house will give off a strong smell of vinegar.

Pour at least one cup of vinegar on the towel. If possible, avoid using sinks that have been treated for hours. If one of the sinks needs to be used, replace the towel immediately and pour more vinegar into the pipe to ensure that the water does not dilute the treatment solution.

After a few hours, remove the towel. Do not rinse the sink, but wait until it is used normally before dispersing the vinegar. This treatment will kill some insects and drive others out of the house or where they have been treated by killers.

At home, we can also take some existing measures to eliminate cockroaches. Cockroaches like the smell of washing powder very much. As long as you sprinkle the washing powder on the ground, cockroaches will eat the washing powder and die. This method of removing cockroaches is very efficient, direct and simple, and will not have any side effects.

This is a very convenient method, which will not affect your home life and can effectively eliminate cockroaches.
