I hate to dissapoint you but normal trails can also last for hours. It's just an indication that the air is more humid.

Anyway if someone wanted to spray us all with they would presumably want to do it in a way that makes sure they disperse over a wide area rather than stay in nice straight lines. Perhaps it's the ones that dissapear quickly you should worry about
