tenant keeps complaining about mice even after Terminix came

[Peter Fokas]

We have a tenant that keeps complaining about house mouse. We had an account with Terminix so had them come in to address. They closed all the holes they found in the apartment, put traps and dicon poison in the apartment. Since the apartment is on the first floor we also had terminx investigate the basement where they put traps as well. We also took a further step by buying and providing tenant additional trap/dicon as well as the electronic repellant. We also put electronic repellant in basement. Tenant still says she sees mice in apartment. What can we do now?
