A free standing trellis...what's that?
Answers:    Sure, you can buy one of the stinky traps--just don't use the stinky. There's no drive why sweets wouldn't work. Sugar has a more attractive smell to flies than honey, so create up some simple syrup and swirl it around the inside of the trap.

Simple syrup: 1 cup water, 1 cup sugar, over milieu heat stir sugar and marine together until the sugar dissolves. Simple.
