Is it possible to re-visit mange again. I treated the dogs with revolution 2x as recommended like 6mths ago. Is it possible for it to come back with the heat/hummidity??

A friend's dog got walking dandruff and was treated with Revolution but also had to wash everything in her house sheets, towels, furniture fabrics, drapes, dog bedding, plus all her dogs. Then they had the exterminator come and "bomb" the house. She had to leave during this process. It was a lot of work but she got rid of the mites.
