That question is the hardest of any to answer.It is all depends on the food supply,the available denning areas,and what kind of population exists.
If you have everything available that a coon needs,they will migrate to that area. But here again, the existing populations of the surrounding areas must be known.If you have a high coon population,don't worry about it.
I run into the same thing with beavers,I just go in and clean out an area,if the food sources and water they need are available,they move in to fill the void I have made.
I have been trapping all the beavers I can take,in one area for 12 years now,they just keep moving back in.
