Just when you thought the world was finally running out of places to put advertising messages, a team in Germany has found a way to tie small paper ads on to insects, specifically flies. 

These inset advertising ads and string (or leash) are light enough for the insects to carry around and are virtually impossible to ignore.  This guerrilla tactic could open up a whole new way for marketers to spread their messages, although no initial costs were revealed.

Only one question remains… What will insect activists think?
