Pheromone is a card type that is unique to the Beetles race. Pheromones can only be brought into play by the Pheromone Pod. They are similar to upgrades, but only affect cards in the same location as the Pheromone Pod. There are five pheromones:

There is a maximum of 1 Pheromone Pod per location, and each pod can only support one pheromone at a time. As such there is a maximum of one pheromone per location.

To activate a pheromone, remove the current pheromone from the Pheromone Pod (if there is one), place the new pheromone face-down underneath the pod, then engage both cards once. When the stack reaches the ready orientation, turn the pheromone face-up; the pheromone is now active.
