It's all this rain we've had. It's flattened their nests to where I don't see them and I get bitten when I take the dogs out, my feet have bites all over! It's also driven the small black ants into the house! I use hydrocortisone cream and Neosporin on the open blisters. Sarna might help too (it helped the itching when I had poison ivy). I hope you feel better soon.
