Its hard to get them out of the house once they have moved In, it would require opening up the wall to get them out. Not sure if that what's your looking to do. FYI I'm not much of a carpenter haha.
didn't know if you wanted to try a trap or not... this morning there was hardly any coming out of the house... Was weird they started coming in abut 3 weeks ago and then yesterday they were swarming outside the hole
Unfortunately a trap may have worked only before they moved back in. You want them to choose the trap as their new home instead of your wall. The only way now is to physically remove them from the wall.
