Thanks for all the suggestions.
Boric acid seems the way to go for a start.
I am going into town on Friday I will pick some up after I have picked up my new bike lift.

Somebody sent me a link about ants eating cane toads. I wish they did, we kill cane toads everyday on our property. Caustic soda works every time.

I would like to see the ant that can eat one of these.
