I wonder if catfish would bite web worms.
I know that we catch cats mixed with bluegills under the pecan and persimmon trees when the water is right and the worms are there. The web worms sure do work for bream.
Toledo, I haven't found a roost around Catahoula or in the surrounding area or I'd try it. There are a LOT of them that roost in Williams lake but the only cats there are of the olive colored type.
When in doubt, pee on it.
