How long do you guys let traps set at a property without catching anything before you move then and reset at a different property.

I leave mine until I get tired of checking them with nothing in them. I know some ppl that leave them in the same place all season. Some trappers hit an area for two weeks and move on. When one pulls one's traps is really an individual decision with lots of facts to consider. If it is your livelihood then not too long because your job is catching animals and if it a side thing, then it is probably longer. It also depends on how much property one has available.
