You need to hit this thing head on! It wasn't the hardest thing to get rid of but everyone got it expect one cat. 2 dogs, 2 cats, 2 kids, mom all got it and it wasn't just one place alot. My daughter's prom was coming up when she got it and she tans real easy, so before prom she went to a tanning bed a couple of times only bad thing was where she had gotten ringworm she didn't tan, she looked like she had tan & white poka dots on her skin, so embarrassing..Shampoo and give the medicine(make sure you feed them something with fat in it) also vaccum your floors and mop everyday, because they can get in the carpet..It took us a good month or 2 to get rid of. Hang in there, but I would start treating everybody now and continue it for awhile. After all the fun of having it you will have a spot a bug bite or just something that will make you think OMG not again...lol
