Custom Baits Built by Hand — Not Machines
Every jig head and soft plastic bait is poured, painted, and packed by real anglers. Because crappie fishing deserves more than factory-made bait.
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.
Testimonials

The 2" slab snack swims just like the real thing. I’ve been fishing crappie for 20+ years — these baits flat-out catch fish.
Jeremy M., Mississippi -
You can tell these aren’t mass-produced. The jig heads are balanced, sharp, and durable — love supporting a small business that gets it.
—Brittany R., Arkansas -
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!
