I wouldn't suggest starting a trap-out if you will not be able to monitor it on a regular basis. There are too many things that can go awry on a trap out that need to be addressed rather quickly. (ie. new entrance, clogged funnel, etc)
Just do it as a cut-out. If you are worried about the population being big, just use a bee vac and reduce the amount of bees before you start cutting out the comb.
