follow-up on robbing question?

Now that the robbing that i had going on by the yellowjackets has stopped, I think, How long should I keep the robber screens on? they seem to be having problems cleaning thier hive. and are stacking debris and dead bees up in one corner. robber screens have been on for about wk and half. have alredy removed one and cleaned it out replaced it. should I continue this or can i remove soon?

Hard to say but I base it on visuals. When I see "normal " entrance activity, I take off the robber screens. For me, that usually seems to be a slow day at the entrance!
