Lots of people use pyrethrin dust as a preventative. Sprinkle it in the dust bathing areas. DE is also widely used this way, and wood ashes evidently also help, used this way. I do a lot more preventive dusting of the coop, litter and dust bath areas than I do actual dusting of the birds.
Actually, it isn't so much preventative, as it is controlling or managing. You aren't repelling them, you are keeping numbers manageable. They are going to be exposed to lice and mites; all it takes is a wild bird flying over.
