I did lime wash one of my huts this year, mite problem horrific like everyone's. I personally was not impressed, you have to do every bit or the mites come back, but found with creosote it soaks into all the cracks and kills the little wotsits and eggs. Wont bother with lime wash again for me but a lot of people have good results with it. You could try it and see how you go on, its cheap enough. Made the hut lovely and light though.
