Grubs are effective for bass fishing due to their realistic imitation of natural forage, versatile rigging options and irresistible action of their curly tail, making them successful in various conditions and water types. They mimic baitfish, crawfish, and other small creatures, and their subtle or vigorous tail action can be customized to attract bass, especially on pressured or finicky fish. Grubs can be rigged to be fished on the bottom, mid-water, or on a drop shot rig, and their compact size makes them great for targeting specific structures.
