Flathead catfish rarely bite cut or dead bait the way channel and blue catfish will. State wildlife agencies describe them as hunters that want something alive, holding to one specific piece of cover -- a log, an undercut bank, a bridge piling -- and feeding mostly after dark. Fish live shad, panfish, bullheads or crawfish close to that cover in the evening and overnight, and skip the chicken liver and stink bait that work on other catfish.
Why flatheads want it alive
South Carolina's SCDNR describes the flathead's diet as mostly other fish, and notes that unlike other catfish, flatheads are reluctant to take decaying bait. Missouri's MDC is more direct: flatheads are not scavengers and rarely eat dead or decaying material, and only live or freshly killed bait works well for them. That single habit separates flatheads from channel and blue catfish, which will readily take cut or soured bait.
Where they hold
MDC reports that adult flatheads hold near cover such as submerged logs and drift piles, usually just one or two fish per spot, and each fish tends to return to the same resting spot day after day. Virginia's DWR adds that flatheads look for overhead cover -- water under trees, undercut banks, and bridge or dock pilings -- calling pilings an excellent place to find them. SCDNR notes they favor deep holes in sluggish or slow current in medium to large rivers, and also turn up in reservoirs, though they grow more slowly there than they do in rivers.
Best bait, and what to skip
North Carolina's NCWRC names live shad, panfish and bullhead catfish as the preferred baits for large flatheads, with crawfish working too, and says flatheads are rarely caught on chicken livers or stink baits -- baits that catch plenty of other catfish. Where it's legal to collect your own baitfish on the water you're fishing, keeping them lively on the hook matters more for flatheads than it does for channel or blue cats.
When to fish
Virginia's DWR calls the flathead an ambush predator that primarily feeds at night. That points to an evening-into-night trip rather than a midday one, timed to when a flathead leaves its cover to hunt.
How to present it
MDC reports that anglers probably take more flatheads on trotlines than by any other method, with jugging and still-fishing by rod and reel also productive. Fishing rod and reel, the goal is to keep live bait working near the cover a flathead is holding on rather than casting away from it; a rig that lets the bait swim naturally along logs, drift piles or pilings without constantly hanging up gives it the best chance. Flatheads commonly run 15 to 45 inches and up to 45 pounds or more, so size hooks and tackle for a fish that big, not for a panfish.
Common mistakes
Soaking the same cut bait that works for channel or blue catfish is the biggest one -- MDC and NCWRC both note flatheads mostly ignore it. Fishing the bright middle of the afternoon instead of evening into night is another. And working open water instead of structure: flatheads hold tight to one specific log, bank or piling rather than roaming, so fishing the same piece of cover thoroughly beats covering a lot of water.

Frequently asked questions
Will flathead catfish bite cut bait?
Rarely. Agencies report flatheads are reluctant to take decaying or dead bait and that only live or freshly killed bait works well, so live shad, panfish, bullheads or crawfish are a better bet.
What time of day are flatheads most active?
Mostly after dark. Virginia's DWR calls them an ambush predator that primarily feeds at night, so evening into the night is usually the most productive window.
Where should I fish for flathead catfish?
Tight to heavy cover -- submerged logs, drift piles, undercut banks and pilings in deep, slow-moving water -- since MDC reports adult flatheads tend to hold in the same spot day after day.
Is it okay to move a flathead catfish to another lake?
No. Flatheads are considered invasive in many waters where they've been introduced and can hurt native fish populations there; NCWRC and other state agencies ask anglers not to transport them between waterbodies.
How big do flathead catfish get?
SCDNR lists a typical adult at 15 to 45 inches and 1 to 45 pounds, with some growing well past that; South Carolina's record flathead weighed 79 pounds, 4 ounces.
