Scot, you need to trap & dispose of those HOSP – they will just keeping back. I would close the box up, then when the HOSP have truly claimed it (you will see both male & female go in & out) you need to set the VanErt in-box trap. This has to be monitored very closely, especially if the blues are still around. If the HOSP go ahead & begin a nest is really the best time to trap them. This is a never-ending battle you must be willing to fight to be successful with the blues. If you unplug all the box holes, the blues will still be able to claim one, and you can use the one for trapping the HOSP. This usually works very well, using one box for trapping. Good luck.
P.S. we here in Mid-Missouri had 70+ degrees for about a week or more too but it has turned cold again and forecast is for below freezing one night next week.
