@Staci121 How would you kick someone out of your house if you weren't listing it on Airbnb?
It's the same process, but with the extra step of informing the listing service that you've had to evict a guest due to policy violations. In an emergency, it's better to get the people out of your house first and deal with the other stuff later.
If the guest is cooperative, you can avoid the customer service step by sending an alteration request that advances the guest's checkout date and automatically refunds the unused nights. The guest has to accept the change in order for it to go through, but if you communicate the stakes sternly enough, they might take in the message that this is the easy way to get some of their money back.
Whatever you do, don't forget that you're the boss of your own home. You don't need permission to defend it from people who abuse your hospitality - you just need to have clear boundaries and enforce them decisively.
