If you have a large honey bee colony in your building & they die out or get poisoned any uncapped stores left will ferment & grow mould.
Which can cause localised mould spots on ceilings & plasterboard walls.
When a colony is thriving they pose little risk.
Pest control firms are happy to spray insecticide. But I've never heard of any that will take down a ceiling & remove all traces of occupancy. If they don't the above issue could be a problem although usually the smell of brood comb just attracts another swarm to the spot.
