I don't know the species but they are almost certainly pollinators by the look of them. If I had them, I would just enjoy watching them go about their business. If they were seriously in my way, I would try to detach those nest holes and material and move them a small distance out of my way.
On my things to do list today is bundling up and cutting to length a pile of hollow plant stems I saved to make nesting material to attract leaf cutter bees and any of three or four varieties of small solitary bees and wasps that work my flower beds.
