Mice problem help needed

[Shlomi Twinner]

Hey guys I own a rental property in Philadelphia. The property is occupied for 6 month and for the last 3 month we have a mice problem. I did everything I can to fight it. Working on the house to close holes (very difficult with tenants inside), stuccoed the outside of the house, replaced and sealed basement windows and more. Also brought an exterminator that did some work. We are considering letting the tenants brake their lease and move. I need help to fight the problem. If you are an expert, or know an expert, or you dealt with this kind of problem in the past please contact me. Thank you so much
