If a mouse or a field rat gets into the water with a bass it is going to get eaten. These mice and rat imitations are proven patterns that catch bass from ponds, shallow slow moving rivers, and lakes wherever bass exist. Cast them on lily pads, hydrilla and in grass beds. Where ever there is lots of vegetation near water there are mice that need a drink of water. These deer hair flies are realistic imitations of the real things. The long tails and details such as ears, eyes and hair that breathes in the water add life-like action.
