Why do pitfall traps have two containers?
Cups are placed in holes in the ground that are dug with a golf course cup cutter, which minimizes impact to the surrounding area. Two cups, one inside the other, are placed in each hole so that that any rain water will fill the bottom cup and float the top cup upwards to prevent loss of the trap contents.
