I had fire ants when we lived in AZ! Terrible! I was attacked by them when cleaning and I basically ran screaming down the hallway, ripping off my clothes and jumped into the shower. Finally, I put on one of my husband's mechanic jumpsuits and gloves and shop-vacuumed the house, sucking up those little creeps. I'm sure that DH would have done this, but he was deployed at the time. I put traps everywhere--including the body of the shop-vac. I also sprayed the perimeter of the house. I try to go with non-toxic solutions to this stuff, but my earth-friendliness left at the arrival of those little devils. Also, pests in AZ can be deadly. Sometimes, they just arrive, regardless of cleanliness. I was keeping the house spotless because we were selling, so I was sweeping, vacuuming and dusting daily.
