You must have brought something that were for free or bought stuff made wiht used product. Sometimes, people who sell the matres, sofa or so so with old material do not steralize the reused product properly. Though, there is a federal law to sterelize the used products, there is no special procedure, so people reusing that just spray some normal pest control chemical, that doesn't help to kill all of the bugs present.

 So, it not possible to do anything, as those bugs are usually stuck in matress or sofa's part that it not possible to find out. In the program I had seen, there were dogs trained to find it out.

So you better get rid of all of those product, before they get into other things. If they have already got everywhere, throw everything clothes stuff and move into new apartment.
