fire ants and mulching

i have been slowly fixing up my garden/yard and before i put down a weed barrier and mulch around my raised beds, i was wondering if anyone knows what other options i have that might keep fire ants out of my garden. rocks? paving stones and sand? recycled rubber mulch? what do you suggest?
