Tenant not paying last month rent

[Harita Konjeti]

Hello BP team, need suggestions how to solve, One of my tenant renting 5 for years, was given 60 days notice to vacate the property with lease ending on 8/31. On 8/1 he sent email that he is officially vacating the house on 8/3. Today when i went to take over my house, all his belongings were there. Pet hair flying all over. He took his TV and sofa. Every room is filled with stuff. What can i do at this time? He did not pay rent for this month.
