I have become infested with red ants in my garden. Red ants are nothing uncommon here in South Fla. but they have struck in one of my garden beds. I have bush beans, corn, and lettuce planted there. The corn I am pretty sure is done for, they are in all the stalks, and where the corn cobs were growing, they are now nesting. My beans and lettuce are not infected as of yet. What can I do? or, Do I need to just rip up everything, kill the ants, and start again before it's too late for planting? If the suggestion is kill the ants, is there any way other than pesticides that you can think of? Thanks so much for the help.
