Fire Ants and Rain

Fire ant bites are said to among the most painful for ants. According to the entomologist you usually get a red itchy bump with a white puss filled sack. Is it just me, I don't remember getting the white puss filled sack, but according to her, thats what you can expect.
I had no idea that the colonies can run so far underground (7feet). That is quite amazing. There is a whole other world under our feet.
