One of my Tenants have been compaining about mice. I have acted promptly and taken various steps to try and rectify the problem. I have even used a combination of treatment options as well as consistent extermination visits approx every 6-8 weeks. I have other tenants and units but only these people in this one particular unit complain. I am polite and continue to send professionals to provide treatment to the entire building.
Recently they have been complaining more being hostile and now refusing access to their apartment to let the exterminator in. At he same time of refusing access they have threatened to withold rent.
Is this grounds for eviction?
When can I enter their apartment without their consent if they continue to refuse treatment from exterminator ?
