For models with extended Higgs sectors, minimizing theone-loop effective potential and calculating tunneling times between physicaland non- physical minima can provide a competitive phenomenological constraint.In this talk we will discuss the method for finding all the minima of the potential and tunneling times implemented in the software package Vevacious. As anexample we will take a look at charge- and color- breaking minima in the MSSMboth at zero and non-zero temperature. We will see that when requiringcompatibility with other phenomenological constraints, vacuum stabilitypresents an even more challenging scenario for this model.
