* Specificity: Collective nouns often describe groups of animals with a common purpose or behavior. "Bee killers" is a broad term that could encompass various creatures (bears, wasps, birds, etc.) with different motivations.
* Negative Connotation: "Killer" suggests a negative action, which isn't usually associated with collective nouns.
Instead of a collective noun, you could use descriptive phrases:
* A swarm of bee predators
* A group of bee hunters
* A collection of bee-eating creatures
You could also be more specific, depending on the context:
* A pack of honey badger bee hunters
* A flock of bee-eating birds
* A colony of wasps preying on bees
