I have heard that cornmeal will work too. The idea is that they bring it back home & after they eat it, the cornmeal expands and they explodes!
I also found this recipe: 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.
Some people suggest keeping them away with cinnamon. Got to try this one some time, because I like the smell of cinnamon. That explains it, maybe that's why I leave my dried apples (sprinkled with cinnamon out for days in the food dehydrater & have no ants ???)
