Natalia, it's summer time in GA but in 47 reviews, there has not been one complaint about a roach. You also communicated with me many times during your stay and there was no mention of that either. I would have taken care of it for you, as I did other things you requested. Since that's not a problem in the house, and there are insect repellents everywhere to manage the critters that run around in the summer months; it's likely the 2 roaches came in to the house with your things, because you left the house messy with food in the bedrooms and office.
You also violated the house rules and brought extra people that were not booked on the reservation. So perhaps they came in with your extra guests. I'm not sure; I'm sorry you had that experience, I will let the pest control people know that, so they can take extra precautions during their routine visits. The next time you book on Airbnb, please be honest with your host. We all work very hard to provide a safe and hospitable environment for our guests; when you break the rules, it jeopardizes this platform.
