Fire ants were all over my lawn last month. They seem to have found my property a perfect place for their nest. Since the weather was generally dry and hot a few months ago, the pest control team said they'd use a baiting method. The nest was a few yards away from my backyard door so they said it was safe.
They spread out grains of ant bait which was supposed to kill the colony in a weeks time...and thankfully, it worked.
