OK....I talked with an Entomologist this past week and when I ask him about using spray to kill the ants in our firewood while it "Cures" He told me that if the wood is kept away from water the ants will not stay. They need water to live and will not live in a wood pile that is dry. He also told me that he would not burn any wood that has been sprayed with anything that kills the ants. I put allot of faith in in knowlege of both the life cycle of bugs and the side effects of the chemicals used to control creepy crawlies.
