We are moving to a new house, but it has a flea infestation. The old owner told us that they had animals and they havent lived there for almost 4 months. What is the safest way to get rid of them before we move in. I treat my Daisy and Mack with Triflexis monthly, but we cant walk outside or through the house without fleas getting all over us. Should i call an exterminater or try to do it myself. I really dont want to move in until the fleas are gone for good. Please, any suggestions will be appreciated.
