If you ever have your home infested with bed bugs, their eradication is simple. You need to have a bedframe with countable legs, a bug-proof plastic mattress cover, and a bag of diatomaceous earth. You simply zip the cover over your mattress, and put a 1cm layer of diatomaceous earth around the feet of your bedframe. The bed bugs naturally come out to feed on you at night, then find burrows to hide in during the day. Normally they'd hide in the crooks of your mattress, but we've already prevented this. They are forced to walk down your bedframe, and over the layer of diatomaceous earth, which causes fatal ruptures in their carapace. Bed bugs can only live about a month without feeding, and you should expect any small to medium sized infestation to resolve in this timeframe, certainly any infestation which might arise from picking up a few bed bugs from traveling.
