Bats are protected so their nests cannot be cleared out (interpret that as you may.) They will remain safe and sound until mid-August when all kinds of nonsense will take place. We will basically hint that perhaps they have overstayed their welcome and then install a contraption to discourage their reentering their/our home.
This will take place after our return from a house in Colorado where sightings of mice, voles, bears and mountain lions are not uncommon.
Did I mention that I have a headache?
