Hi @Garrett120
Airbnb does not have home insurance they have a limited Guarantee. Have a look on the Airbnb Help website and you can see the areas they cover.
You can also have a look at your home insurance for short term lets and see if squatting are covered in terms of your liability but I very much doubt it.
Much better not to put your property and STR business at risk of squatters only accept bookings that don't put you at risk of squatters. Or if you want to take longer term do long term bookings create a tenancy and do appropriate credit checks, tenancy checks etc.
