You forgot to mention VASOR136, a trace vapor detection unit that is very versatile. The VASOR 136 holds 36 bees in cartridges. They are all ready to detect the presence of something in the air.
See here. Of course, that article is a bit light on information on detection thresholds, false-positive rates and so on as compared to dogs, mass spectrometry or chemical detection methods.
I will also note that humans have 10-20M olfactory receptor neurons, while bees have 1M neurons in total. Probably bees are under more evolutionary pressure to make optimal use of their olcfactory neurons, though.

This is no BS or joke.
