I drove cross country last year and saw signs of bedbugs in 3 of the 4 stops I’d picked out ahead of time. One of them was straight up still treating the room and even using a home remedy (had diatomaceous earth scattered all around the room) and then told me to my face they didn’t know what I was talking about. From what I hear, it’s only getting worse.
Airbnbs might not be any more professional about handling the situation, but at least they handle a smaller volume of people.
