I didn't know cinnamon would work. Nice idea!
Sounds like preflavoring for my next project - I'll feed them sugar like richq11 suggests, sprinkle them with your cinnamon and pour melted chocolate down their nest ( instead of molten aluminum )
Turn the little fellas into a tasty cash crop of sweetened cinnamon chocolate ants! If we could figure out a way to get cherries and pretzels into this mix we might be on to something here - lol
hahaha -- that sounds like a plan!
