In some parts of the world a mosquito bite is a minor inconvenience that might result in a few days of uncomfortable itching. In other parts, though, the pests spread deadly diseases like malaria and dengue fever. So for the 2014 World Health Day, ad agency Leo Burnett created the world's first mosquito-repelling newspaper in Sri Lanka.

A rolled-up newspaper is often used to battle the pests, but the Monday, April 7 edition of Sri Lanka's Mawbima newspaper went one step farther, since it was printed with inks infused with citronella that kept mosquitoes at bay altogether. The paper was also filled with articles providing additional information and tips on reducing local mosquito populations. And in a pinch, it of course doubled as a highly-effective swatter. [Core77]
