Try asking your local feed store. Ask if they can order corn gluten meal, molasses, things of that nature. 10% vinegar, too.
I was quite surprised to find that even feed stores
in Florida did not carry the aforementioned products. What the heck do they feed their animals? I went looking for horticultural corn meal because my grandmother (who previusly lived in Steinhatchee) had fire ants in the path to her burn pile (where she burned her trash) and also in the path to her compost pile. Steinhatchee is quite small, so I went into Cross City and even Gainesville and had no luck at all! I asked for horticultural cornmeal and the old guy looked at me like I was from Mars.
Then I asked for just cornmeal and he told me to try Winn-Dixie or Publix!
Enough of my rant, just give it a try. Maybe you will have better luck than I. There are always places to get things online, but shipping does add up!
