This could work quite well if your organic race is insectoid in origin. Many insects use pheromones to communicate with each other in close proximity to perform tasks, guide each other and warn others of danger.
And, as David mentions in his answer, you can combine a number of simple instructions to add up to complex behaviour. This is the fundamental concept behind Swarm Intelligence, an area of study that is heavily influenced by animal behaviour, mainly that of insects, hence the name "Swarm". Swarm Intelligence looks at how having a large number of creatures / objects working together, each following a simple set of instructions, can lead to interesting and complex behavioural patterns, some of which we can't predict until seeing it in action.
A good place to start with this kind of study would be with Ant Colonies, which utilise Swarm Intelligence to excellent success. Each worker ant actually does very small, simple tasks, in sequence, but because each Ant is following this simple set of instructions, it all comes together like pieces of an engine.
For a bit of science mumbo jumbo, look no further than the Ant-Man movie. In it, one of the devices used is an Electromagnetic Communications Device, which basically allows a human to control nearby ants by sheer force of will.
The scientific explanation of how the tech works is.... admittedly a bit lacking, but what the movie does tell us is that it basically stimulates their olfactory nerve centres via electromagnetic waves, simulating the effects of various pheromones to get them to perform whatever task you need them to.
Basically, for a realistic approach that's based in some form of science, you'll want to make your society insectoid, probably a swarm race, like The Zerg, and have each member of the society have a clearly defined role, so that together they act as one functioning unit.
Extra: It's also fairly common for these kinds of races / societies to have a central intelligence or collective consciousness, where a single hive mind dictates the actions of the smaller drones, but this isn't absolutely necessary.
