Aside from washing all your clothes and beddings in hot water and putting your shoes in a dryer or leave it under a hot sun?, spraying your bed (mattress/bed frame & headboard) and luggage with rubbing alcohol can get rid of bedbugs (as I have read an article about this). And I think it also includes spraying all the furnitures (might cause damage to it)/closets inside your room. I haven't done it since I have not experienced having these tiny critters in my place, but a friend of mine did have bedbug infestation in his apartment and he ended up using a pest control company to fumigate the whole apartment. It did cost him a lot of money .
