There are two items I use to get rid of ants. #1 the easier & most healthy is try Comet. Yeh, that stuff you scrub your sink with. The ant don't like it. It has clorine in it & it seems to work. #2 I purchased fly repelent at the feed store, for my horses, it's called Ronco or something like that, now this stuff will give you a headache, but kills ants. I've used it on red ants & they are hard to kill! Good luck
