the bottem was open. that for shure was the problem. every tbh that i have seen abscound this spring, had the bottem fully open. close it up and ill bet thay stay. could be other things that made them leave but ill bet money it was the bottem. think of a package like a swarm. if the home you put them dosent suite them thay have no reason to stay since thier is no recources thier to protect. make it nice and dark with a small entrance to defend and chances are thay will stay. good luck
