ant problem on my okra
I had some aphids underneath my okra leaves, especially the young ones, I killed them all by hand. And then the ants moved to attacking my flower buds, flowers, and the developing pods. They chewed on the developing pods with no aphids on them. These are fireants. I tried neem oil which only killed them when they were there, and then a new batch came in the next day. I tried cornmeal, they brought it home but didn't die. They don't care about cinnamon, they walk over it. I tried the organic pest spray from Lowes called EcoSmart or something that supposedly would kill on contact but that did nothing at all, they were walking like nothing had happened. I used cayenne pepper that only got rid of them temporarily and then they came back to continue chewing on my pods and flower buds. Now almost all the flower buds were chewed off of the okra plants, I doubt I will have any harvest at all.
These are fireants. What can I do? Help!!! I'd prefer not to use anything toxic.
