Does a month to month lease contract have an end date if it is not stated on the contract?

I have a tenant who needs to be evicted. She's been late with rent 10 out of 12 months a year for the past 3 years. She makes demands and uses the "I'm a single mother excuse" and my husband gives in to her commands. I spent hours writing and re-writing a new contract and she knew two months prior that rent was increasing by $150/month starting 8/1/2021. However, when my husband took the contract to her, she said the new rent of $1200 would be paid on 9/1/2021. So she didn't sign the contract and my huband didn't say a word but left the rental and came home. He didn't tell me. I found out through her. She argued with me how she had bills, a kid, and she even used the excuse "life" whatever was meant by that. Basically, her bills aren't differen't than the rest of America's bills. I want to evict her. Am I able to do so even with the pandemic still being taken care of? Please help, I need her out.
