Hey shewolf-good to see ya.
The cornmeal or diatomaceous earth works because ants will eat anything. I don't know if eating cornmeal kills them quickly because their digestive systems stop functioning after trying to digest cornmeal or for some other reason. Maybe it, like diatomaceous earth just rips up their tummies. Cornmeal might actually be better because it is probably too coarse for earth worms, so they wouldn't be put at risk.
I need to look it up to see how it functions.
Here are a few solutions:

i have found LOTS of ways to get rid of them, vinifar, cayenne, citric extracts, cinnamon, cream of tartar, salt, and belive it or not purfume! you can use cloves, peppermint oils, black pepper, chili powder and cornmeal. you can also make something that will kill them using 1 part active yeast, 2 part mollasses and 1 part sugar. or u can use grits and that will make them explode.... but use instant grits, they work better and yea thats all i found oh yea if u put half ivory soap and half windex in a spray bottle it will kill them good.
Here are a few of Jerry's tonics for critter control.
ANT CONTROL TONIC #1
4 to 5 tbsp. cornmeal
3 tbsp. bacon grease
3 tbsp. baking powder
3 packages of yeast (I would opt for the rapid rise)
Mix cornmeal & bacon grease into a paste, then add baking powder &
yeast. Dab the gooey mix on the insides of jar lids, and
set them near the ant hills.
When ants eat this mixture, they swell up and go to the big ant hill in
the sky.
Cut pieces of the herb tansy and put on windowsills and other places they enter.
