I am sorry, but you are wrong on that one. A systemic insecticide works through a plant and kills when insects, etc, bite or otherwise damage a plant part. Bees can sometimes pick it up when they go into a flower, as bees do. They can then carry it back to the hive and eventually kill the whole hive. You don't have to actually spray the bee to damage it. Humans need bees, so I won't use this type of killer.
