A grub is a soft plastic bait that ranges in size from 1.75”– 4”. Sometimes larger if used for saltwater. With its curly tail vibration and slender body, grubs are very successful at imitating bait fish. The two most common types of grubs are twin tail and a single tail, and they come in a variety of colors. Go try one today. Rig it up to a jig head and cast it out. When that tail starts kicking around in the water you are bound to get some bites.
