Here is a trick I learned a few years ago. It is extremely useful in getting bait using only things you find in the woods and a bucket. Most species of freshwater fish will eat a worm; it's arguably the best all-purpose fishing bait. Be sure you choose a rich, preferably moist area, sch as next to a creek or river. Worms like these areas better than dry, rocky terrain.
You will need:
-Bucket (preferably 5 gallon)
-Smaller container for rinse water
-Black walnut tree dropping walnuts (you can also use liquid dish soap in place of walnuts)
Let the video explain the rest...
