A roof infested with hives
Wasps and bees are hard workers, so they don’t hesitate to construct their hives when they come upon a suitable site. Because they live in such large societies, their hives may be enormous and fill entire rooms. They can create a hive of thousands of bees within a big enough area, like your ceiling.
This image makes us cringe. We’re still flabbergasted by the number of bees this person discovered nesting in their home. How did they get rid of them? The bees can sting you if you approach them too closely. If you receive multiple stings and develop a potentially fatal allergic response, this might be harmful.
