Fire ant bites never go away. After the blister the bite is there in some fashion a bump or a scar. During the season, when the young queens leave the nest the swarms look like mosquito swarms “The Naked Jungle” Deadly in Texas not even frogs, turtles are spared. They must have been put here for some reason....but the answer to that has not yet been found.
Here in SC, we see the ant mounds appear overnight. It’s amazing. My wife pours bleach down the mound. I prefer to use poison crystals that the ants carry back to the nest for consumption.
If you rub the mashed leaves from an impatiens plant on fresh bites- or the wild jewelweed, there will be no pain, no bump, no scar, or at worst not much of one.
