Largemouth bass will bite on almost anything. They can be caught on minnows, worms, or other live bait, plus poppers or streamers presented with a fly rod, or plugs thrown from a casting or spinning rod. Because the bass is usually associated with weeds, a weedless bait will often be necessary. Best fishing times are early morning and evening during the warm months. Bass like warm water and warm weather. Few bite in the winter.
