We develop a model to study tetraquark production in hadronic collisions. We focus on double parton scattering and formulate a version of the color evaporation model for the production of the X(3872) and of the T4c tetraquark, a state composed by the ccˉccˉ quarks. We find that the production cross section grows rapidly with the collision energy s and make predictions for the forthcoming higher energy data of the LHC.
