For perfect crime, criminals should not leave any traces at the scene of the crime. Nicholas Wig, thief, was arrested because he forgot to log out of his Facebook page before leaving the criminal site.

Use Coffee Grounds to Get Rid of Ants

Summary : Coffee grounds are natural alternatives to the insect spray since insects tend to avoid strong smell of the brewed coffee. In addition, it is economic and eco-friendly way to ward harmful insects off.   

Persuasive : In general, people believe using chemical pesticides is the best way to  get rid of insects. However, this article shows that natural alternatives also works well. What's more, it is much easier and cheaper way. Therefore, I think it is better to use coffee grounds as insecticide rather than chemicals.
