pheromone code?

so i'm making an ant mod, and i was wondering if there was some sort of procedure where if the entitie was attacked at [x] [y] [z] then it would execute a different procedure, which other ants would have, where when they received it they would patrol to [x] [y] [z] and then return, i feel like this might not even be possible, but if it is, i would like to know how.
