We have fire ants here, I mix a paste of meat tenderizer with papin in it. Slather it over the spot bitten and let it set and dry. If it doesn't ease up, I do it again. But it's best to do it as soon as you are bitten. My DH has a bad allergy to them.
I love this post, interesting to hear what's going on in other parts of the world. It's 1 pm here in Florida, sunny, hot and very humid but the clouds are forming. We got rain last night late. Have had sprinkles to downpours nearly every day for two weeks. It's a good thing as Florida had been very dry with extreme drought conditions in some parts of the state. Now some are getting too much........can't win.
