How can I evict a tenant for non payment of rent in WI,

She shares an apartment with my son, his wife and daughter. I gave permission for my son and daughter in law it move in and she came along. I told he when I found out she was there that she would have to find another place and pay rent ,300/month, until she did. She has not found another apartment and has missed the rent 2 months in a row. She had missed before but I allowed her to make it up on subsequent months. payments. I have had it with her and want her out. I told her this and took her to the Disability Resource Center . They are seeing if she qualifies for disability housing somewhere. She was supposed to be looking for something in case she does not qualify. She has not been doing that. \
