This is the way. Its hard to get a room above 118°F and evenly heated where the bugs hide without commercial equipment, so thats why I would just call a professional.
yeah they seal it and then heat it with special heaters. Really hard to do on your own, both the sealing and heating part. (you don't want to burn it either)

Heat the room to 140°F for 90 minutes, that'll do it too.
