Who knows, grits may or may not be the answer...they did little for my
fire ants.  Here in Texas they have become a major pest around the bee
yard.  In some cases completely destroying hives!  For fire ant control
around the bees, you might try a mixture of compost (or cow manure)
"tea", liquid molassas, and citrus oil.  That seems to at least run them
off.  Howard Garrett has a good web site for "organic" remedies
including the fire ant mixture above.

If anyone has a better solution that doesn't hurt the bees, let me know!
