FAITH. FAMILY. FISHING.

Born in South Louisiana, Kill Um’s Jig Co. carries generations of crappie-fishing tradition. From our family’s hands to your line, every bait is made with heart.

Handcrafted. Water-Tested. Slab-Approved.

From mold to water, every jig head and soft plastic we make is designed with purpose — to mimic real baitfish and get bites when the pressure’s on. No shortcuts. Just results.

  • The 2" slab snack swims just like the real thing. I’ve been fishing crappie for 20+ years — these baits flat-out catch fish.

  • You can tell these aren’t mass-produced. The jig heads are balanced, sharp, and durable — love supporting a small business that gets it.

  • I’ve used big-name brands for years, but Kill Um’s baits consistently outperform them. Caught my personal best this spring using the Slab Twister!
