Now you know you have bugs in your bed so you must keep them contained somewhere to get rid of them as soon as possible.
A simple way to trap the bugs is with your vacuum, run the vacuum over the hiding places for example bed, carpets etc. quickly seal the vacuumed contents into the plastic bag and throw it away. Make sure to clean the vacuum as well to avoid any risk again. Now put the infected clothes or linens in the plastic bag and wash them thoroughly, after that put them on the highest possible temperature. If the clothes cannot be treated even by washing then throw it away immediately.
In case of furniture clean it but if you think that cleaning would not help then throw the furniture as well.
