The thing is u cannot. I had same problem. Dump all the infected mattress, pillows. U can wash blankets. Everything that goes into new apartment needs to be washed. When u wash ur clothes don't take them to ur old place. Don't even take Couches. Tables and chairs(metal or wodden) should be fine. Buy Hot Shot Fogger from walmart and spray into ur new apartment with all windows closed after u have carefully transferred them into new apartments.
