Bed Bug treatment on devices

Hello, I am hoping I can get some sound advice. My daughter's apartment building has become infested with bed bugs. She has been struggling all week trying to remedy the situation and her landlord has not been much help. She will be coming home and we are looking for ways to help her come home safely and not share anything that may travel with her. She is leaving almost all of her things in the apartment, but I am concerned about her iPhone, watch, and laptop. How can we tell if they have been infested and if so, how can we treat them to keep them from coming into our home? I am really nervous about all of this and want to be safe. Actually, I am scared to death of getting them in our home. Any help is greatly appreciated.
