Bill Lewis Rat-L-Trap

The World's Best-Selling Lipless Crankbait

For over two decades, the Bill Lewis Rat-L-Trap has been the top-selling hardbait in the world — and it's earned that title one fish at a time. The Rat-L-Trap's tight, high-frequency wiggle and exclusive Liv-N-Sound baitfish distress rattle trigger reaction strikes from both active and inactive fish. Whether you're burning it over shallow grass, yo-yoing it on a ledge, or slow-rolling it through cold water, the Rat-L-Trap finds a way to get bit.

The Liv-N-Sound Rattle That Changes Everything

The Rat-L-Trap's exclusive Liv-N-Sound system produces a baitfish distress call that bass, pike, walleye, and other predators are hardwired to respond to. It's not just a rattle — it's a specific sound frequency that mimics a wounded baitfish struggling at the surface. Combined with the bait's flashy, chrome-finished body and tight wiggling action, the Liv-N-Sound system creates a multi-sensory trigger that draws fish in from a distance and converts followers into strikers.

Why Soft Plastics Can't Do What the Rat-L-Trap Does

Soft plastics are finesse baits — they work when fish are pressured and need a subtle presentation. The Rat-L-Trap is a reaction bait — it covers water fast, creates noise and flash, and triggers aggressive strikes from fish that haven't committed to feeding. When bass are scattered on flats, suspended over grass, or schooling on shad, the Rat-L-Trap's ability to cover water quickly and trigger reaction strikes makes it the most efficient search bait in the box.

Three Sizes for Every Situation

The Rat-L-Trap comes in three sizes to match any forage size or fishing situation. The 1/2 oz is the classic all-around size — ideal for spinning or baitcasting gear, shallow to mid-depth presentations, and most freshwater applications. The 3/4 oz bridges the gap for deeper presentations and larger forage. The 1 oz is the big-water, big-fish version — built for open water, deep structure, and situations where a larger profile and longer casting distance are needed.

The Right Pick If...

• You need a reaction bait that covers water fast and triggers aggressive strikes
• Bass are scattered on flats, suspended over grass, or schooling on shad
• You want a versatile bait that works from the surface to 20+ feet
• You're fishing cold water in winter and need a slow-roll or yo-yo presentation
• You want the world's best-selling lipless crankbait with a proven 20+ year track record

Best Retrieve Techniques

• Burning: Fast, steady retrieve just below the surface — the classic Rat-L-Trap presentation for covering water and triggering reaction strikes
• Yo-Yo: Cast out, let it sink to the bottom, then rip it up and let it fall back — deadly in cold water and on suspended fish
• Ripping Grass: Retrieve through shallow grass until it fouls, then rip it free — the sudden burst of action triggers explosive strikes
• Slow Roll: Slow, steady retrieve near the bottom — effective in cold water when fish are lethargic
• Countdown: Let it sink to a specific depth before retrieving — ideal for targeting suspended fish at a precise depth

Best Conditions

• Shallow grass flats — milfoil, hydrilla, coontail, and eelgrass
• Open water and main lake points when bass are schooling on shad
• Cold water (winter and early spring) — the yo-yo technique is one of the most effective cold-water presentations in bass fishing
• Stained to moderately clear water where the rattle and flash carry
• Any situation where covering water quickly is the priority

Tackle Express Tips

• Size to the Situation: Use the 1/2 oz on spinning gear or when targeting fish in shallow water (2–8 ft). Step up to the 1 oz when you need more casting distance, deeper presentations, or a larger profile to match bigger forage like gizzard shad.
• Ripping Grass is a Game-Changer: The Rat-L-Trap's tight wiggle lets it cut through shallow grass without constantly fouling. When it does snag, a sharp rip to free it often triggers an immediate strike — the sudden burst of action mimics a baitfish escaping a predator.
• Match Color to Water Clarity: In clear water, go with natural patterns like Chrome Blue Back, Lectric Silver, or Threadfin Shad. In stained water, reach for high-visibility colors like Chartreuse Flash, Red Crawfish, or Cherry Bomb. Craw patterns like Natural Crawfish and BNB Craw shine in rocky, crawfish-heavy fisheries.

FAQ

What size Rat-L-Trap should I use?
The 1/2 oz is the most versatile size and works on spinning or baitcasting gear in most freshwater situations. The 1 oz is better for open water, deeper presentations, larger forage, and situations where casting distance is critical. The 3/4 oz bridges the gap for mid-depth presentations.

What rod and line setup works best?
For the 1/2 oz, a medium 7' spinning or baitcasting rod with 10–15 lb fluorocarbon or 20–30 lb braid is ideal. For the 1 oz, step up to a medium-heavy 7'–7'6" baitcasting rod with 15–20 lb fluorocarbon or 30–50 lb braid for maximum casting distance and hookset power.

How do I fish the Rat-L-Trap in cold water?
The yo-yo technique is the most effective cold-water presentation. Cast out, let the bait sink to the bottom, then rip it up 2–3 feet and let it fall back on a semi-slack line. The fall is when most cold-water strikes occur — watch your line for any twitch or jump as the bait sinks.
