One of the major pests in the United States today is the fire ant. Fire ants are reddish-black and have proportionately large heads. Dogs and children are the most common victim on fire ant bites in home garden. It’s because dogs and children never seem to learn to stay away from the mounds. Fire ant bites on dogs often produce local reactions with swelling at the site of each sting within 15 minutes. You can go to controlfireants.com to get more information about fire ants.
