- First of all, get rid of the bed. Dont buy a new one for some time.
- Call pest control guys. They have very good sprays and thats the only option to get rid of the damned things. High Street sprays wont work, call exterminators
- Dont enter that room - sleep in some other room
- Wash all your bedsheets and quilts in 60 C hot water
- If you see even a single bed bug in your wardrobe, wash all (YES, ALL) the clothes in 60 C hot water
- They can reproduce from one to 500 in one months, so make sure none is alive
- Take extra care with kids
- They feed on human blood, so (as I have already said) keep away from the infested room
- Call good pest controls guys (It will cost a lot), thats the only way out (I can recommend Rentokil)
I am having a medium infestation and after three sprays, almost all are gone. After the fourth spray, hopefully, they will all disappear
