Well, the person who said to feed the ants is an environmental nut! I hope no body still believes in global warming as caused by mankind. One volcano eruption produces more pollutant than all of the industrial age. I think the best solution to KILL ants is the diatomaceous earth and ant baits. Keep everything scrupulously clean and mop with bleach/white vinegar. I wish I could plant the mint but this is totally desert and growing anything is difficult.
