Will it happen every year???

My goats got mites this winter and they’re almost all gone, this was my first winter with goats, will they get mites again next winter?? I hope not , what are some things I can do to prevent them from getting them again? I clean their pen very often at least one or twice a week , I also give them garlic I think that helps with mites. Hopefully mites aren’t a yearly issue. Thanks again
