@Pamela1117 its unfortunately very common, especially for new hosts.
Some advice? Lower your guest counts. You want to aim for fewer people with a higher price per night to get better guests. You have 4 beds so your max should be 8 guests. Make sure none of your tables have more seating than 8 people.
Make your house rules more robust. Address what happens if people bring extra guests-- will they be removed? Fined? Both? Flesh out your rules and hide an Easter egg phrase that guests have to repeat before booking.
Set your booking only to accept those recommended by other hosts or do a lot of vetting.
Don't make it appear that you are too far away to intervene if something happens.
Wait until the last minute (day 14, 11th hour, 55th minute) to leave your review of the poor guests. Something like "Guests threw an unsanctioned party with 25 people on a reservation for 8. We do not recommend them and would not have them back." Low scores in all categories and "would not host again" button pressed. If they leave you a review you can ask for it to be removed. But as you are so new, I might just deactivate this listing and start over with better rules and screening.
Good luck!
