Two gold for a couple crunchies who might drop a silver between them is a waste of resources. Sticks swing all day and don't cost a dime. I would wager most players could swing 100 damage in less time than it takes to set a trap. 
The only real efficient use of traps is murdering PCs, because they drop better loot.
