I've filed the eviction, they've been served with the paperwork, and now all that's left is for me to wait for the next steps and hope I filled everything out right (Denver county's process is making my head spin, and I'm having to do this without a lawyer because of cost) while in the meantime my tenant is otherwise just ignoring all my texts and notices and also (it feels like) acting like nothing has changed, still having people over for dinner, still walking in and out of my front door like no problem...leading up to this point I've had multiple informal conversations with this person about the toll their unpredictable behavior around payments has had on me.

They also admitted that the bedbugs weren't there until recently and that they likely brought them in but they still feel that I should be financially responsible for removal costs (averaging about $2500). 

That option feels like it will be trying to thread a small-eyed needle.
