OK. I don't know of any spray, but I want to get rid of my bullhead catfish before they spawn again. I put some small bluegill, redear, and channel cats in last fall. Other than that, the pond only has fatheads and some bullheads that got in somehow.
I thought about setting a trotline. I don't want to catch my bluegill, redears, channels; but they may not be big enough yet to bite a hook anyway.
Someone said somewhere that you can chum them with fermented corn so I have some setting in a bucket.
Any tips / pointers?
