I don't have fiah ants but I do have a "seasonal goat rash" that I prefer to think is poison instead of something from mites/scabies/ebola. Itches like a mofo!! Drs were stumped last year so not going back now lol. Gotta love 'em! And that's just my arms...That will require a 30 mile trip...will put it on my shopping list for monday, thank you.
