Termites are not so different to bees in many ways: both are social insects that live in large colonies and have several castes. Both use grooming as a first-line defence against potentially damaging diseases. 
Bayer sells a pestide called Premise that kills termites, which they market on the strength of its ability to interfere with the termites' grooming process. The active ingredient is Imidacloprid, and yet they claim never to have tested it on bees to see if it has a similar effect. Some would say that this a a significant oversight, while others might suggest that it is evidence of Bayer's usual habit of being 'economical with the truth'. 
Whatever we think about this, there is no statutory requirement for Bayer to conduct such research.
