D.F.
My husband is a licensed pest control technician who specializes in bedbugs. Bedbugs DO respond to proper treatment if done well and professionally. Usually it takes two seperate treatments to get rid of them for good. You shoudlnt just destroy bed linen because they dont just hide linen. A bed bug infestation usually means they are everywhere. They hide in the tiniest crevices and are often hard to see. They can be as small as a tick. If you are at a business, you can spot the presence of bedbugs if you see tiny black bugs on any type of linen/clothing, ect. Also, they tend to leave red smears on clothing (dark rust red, its there poop). If you see their presence, you should avoid rubbing up against any type of cloth (couches, laundry, beds, ect). My husband has been to many homes infested with bed bugs (including huge movie theaters) to treat for them and he has never once brought them home with him. As long as you dont rub up against anything and keep aware, you probably shouldnt have much to worry about
