I'd say its completely site specific....it's gonna depend on the habitat type available and the amount of it. I trap in one spot here at the house and caught over 20 for two straight years. I trapped for several weeks each time. The one spot I'm trapping though is located along a main drainage that would cover hundreds of acres.. One thing I noticed was that over time I started only catching small juvenile coons. This led me to believe that I trapped out al the resident coons around me and had started catching young roaming coons looking for a new home. I figure main drainages is likely what young coons use to disperse
