Make sure they don't have any bugs that would love to call the inside of your house home. Water them with soapy water (or the pesticide of your choice) a couple times and wash them with soapy water (or spray with the pesticide of your choice) a couple times before you bring them in. My favorite winterizing product is Insecticidal Soap.
Find them a good and sunny spot indoors to spend the winter.
