How to Use a Crawfish Trap? | Set, Bait, and Soak

Setting a crawfish trap is one of the easiest ways to put fresh bait on the hook, and the basic process takes about five minutes once you know the order. Whether you are working a riverbank or a lake shoreline, the steps stay the same: pick the right spot, bait the trap, close it securely, tie it off, and let it soak. Get those four steps right and you will be checking a trap full of crawfish by morning. The table below shows the crawfish trap settings that matter most.

How Do You Set a Crawfish Trap?

Assemble the trap, bait it, and close it before you do anything else. Pentair AES’s crawfish trap instructions say to join the two halves of the trap, bait it with fish heads, entrails, crushed crabs, or another favorite bait, and close and lock it securely. You do not need to fill the trap with bait. A piece about the size of your hand — one whole sunny or one tilapia fillet — is enough.

Then fasten a cord or chain to the snap eye and anchor it to the bank or dock so the trap does not drift.

Where and When Should You Set the Trap?

Set the trap in water that crawfish actually inhabit. MeatEater’s guide on trapping crayfish says to find a rocky bottom in a slow-moving river or lake and drop the trap in 2 to 20 feet of water. Crawfish hide among rocks, and slow water lets them find your bait. Avoid muddy, silty, or fast-moving areas where crawfish are scarce.

Throw the trap in so it runs lengthwise with the current — not across it, not against it. The official Pentair AES manual notes that best results come from setting the trap in the evening, because crawfish are nocturnal feeders. Set your traps before dark, then check them in the morning.

How Long Should You Leave a Crawfish Trap in the Water?

Soak time depends on the spot. MeatEater says some users leave traps overnight, but in a good spot they may fill in as little as an hour. If you are running multiple traps, check them every couple of hours. In a proven spot, an overnight soak is the standard move; in an unproven spot, a shorter check tells you whether to move the trap.

One thing to avoid: overbaiting. A trap crammed with bait does not catch more crawfish — it just invites smaller ones and makes removal messier. Keep the bait hand-sized and you will keep the trap working.

Some anglers prefer working the shore at night with a head-mounted flashlight, a bucket, a rod, line, and bait. This method targets crawfish that come into the shallows after dark, but it requires care near the water’s edge. If you go this route, wear a headlamp and watch your footing on slick rocks.

Which Crawfish Trap Should You Buy?

Traps vary by size, mesh, and entry style, and the right one depends on where you fish. Frabill’s XL Torpedo Crawfish Trap (model 1273, $44.99) is a vinyl-dipped steel option with a two-piece design for easier baiting and catch removal. The Frabill 17 Inch Crawfish Trap (model 1272) is a smaller, more affordable version of the same design.

Promar’s TR-101 and TR-301 models are rated highly for crawfish at around $29.99. American Maple’s TR-601 is a budget pick at $12.95 with a 16.5-inch trap and a 1 3/4-inch entrance. Protoco’s CT18R runs $44.95, and KTraps offers larger cylinder traps — 24, 30, or 36 inches in length — for $143.00 if you want a commercial-grade option.

Whichever trap you choose, the setup steps stay the same. The common mistakes — overbaiting, ignoring current direction, and using the wrong tie material — are what separate a full trap from an empty one.
