So my players want to domesticate giant ants

A long and uninterrupted interruption of my latest session had the party discussing how they can clear out a small giant ant colony that have been scaring and hounding some miners in a major orc city, upon entering the colony they kill all the ants apart from the massive queen and the eggs and larve

The party consist of (at the time lv2 now 3) A gunslinger A kineticist A bard A magus And a champion

They want to try to or find a person who can synthesize the proper ant pheromone and sounds to train the ants to become a beast of burden, claim royalties over said business, and make some money

I am unsure of how to proceed, but on the brightside i have 2 weeks to think of some solutions.
