I only trap a small section of a local creek in 2D. In the past I have always pulled in at least a dozen or so with the limited hole/blind sets I make for rats. This year I have walked the entire section of creek I trap (about 600 yards or so) and have found little to no sign of rats (i.e. holes or droppings). I have read a few posts and articles here and there about their numbers declining and was curious if anyone else has been experiencing the same thing. This is the first year I have ever connected on mink on this particular creek (have caught three so far - 1 male 2 female). Maybe the mink numbers in the area are the reason behind the limited rat sign I have seen. Thoughts?
