We know that the bed bug metabolism speeds up in warmer temperatures causing more frequent feeding and shorter life span. On one occasion I took advantage of that quirk when a man in care facility insisted on keeping his suite at 30 celcius on a regular basis. The infestation was well advanced which usually means there will be a long drawn out process of collecting the last few bugs out of the walls. In this case it only took 30 days to collect the last bug – primarily because the tenant insisted on keeping the temperature very high. I recall sweating a great deal treating that suite but the bugs had it worse and it worked to my advantage.
If you are using glue boards to capture bugs as they meander out of the walls one way to speed the process is to keep the temperature higher. Perhaps 30c is a bit excessive but it does help.
