Since throw tilam is out due to expensive tilam and fairy new... try killing the bugs.
Sleep in another room, remove all items like bed sheet, blankets, etc and wash in hot water. move furniture near the bed away so reduce the chance of them moving away and hiding and spray with pesticides, repeat again 4/5 days and next 4/5 days. In case bed bugs eggs hatch and cycle continue again.
Not sure what pesticide you can get your hands on...
You can get pesticide bomb and bomb the whole room at night, repeat again few days later and again. If cannot get bomb, spray ridsect in the whole room at night, on the bed, wall, floor, etc... oily residue will kill the bugs if they come out. sleep somewhere or in the living room.
bed bug trap, if you can get one place one at a dark corner and monitor, see if can catch any or not. Last time I suspect was bitten by bed bugs I also did all these, but luckily it was not as nothing caught on the trap.
Other stuffs you can try
bed bug steamer device, steam and heat from the steamer will kill the bugs
UV bug light, run it thru the bed, UV will damage the bug and egg cells so they will die, but if the bugs are hidden deep inside the mattress, it would be able to reach them.
You can try combining the various methods to kill. Good luck
So yesterday I tried vacuuming the mattress edges and sides.. and also used the garment steamer iron steamed the underside of the bed frame and the sides of the mattress as well.. today I will make the trap and see how is it
