It's pretty common to refer to destroying an aggressive dog, for example, as euthanasia. This is an analogous situation, particularly given that, as pointed out elsewhere, honeybees are domesticated animals. I think this could fall under euthanasia for behavioral problems.

I think that's a mistake in terminology. The dog is not suffering, others are suffering. Normally when I hear reports of dogs being killed due to aggression, the word I hear is "killed" or "destroyed".

I think it does actually matter. Killing because of aggressive behaviour is execution, not euthanasia.
