To kill ants mix a little Borax (20 mule team borax cleaner) with sugar and moisten and put on some wax paper. The ants bring to the nest and die. Very safe to use I even give a little borax in my pigeons bath water once a week helps to keep bugs and things off and they drink the bath water with no problem.And yes it is safe been using it for years. There was an article put out a few years ago that Borax was dangerous but that was all dispelled.Since I have never used it in a reptile enclosure I wouldn't just to be extra safe but safer than any of the sprays. Oh does a good job on clothes also.
