I've got them and I don't want them, so now I have to figure out how to get rid of as many of them as possible.
The big ones are pellet hogs so they won't be a lot of trouble to catch out.
It's their babies that are going to be the problem.

I'm thinking I'll start by building a couple scaled-down B traps. Use 1/4" mesh and make the opening say 1/2"x 2 1/2" and see how that does.
I catch a few every day in an unbaited torpedo trap, so I have to think the B trap will catch a lot more of them.

Seining is an option. I have a 4'x20' seine. Probably need one more along the lines of 6'x40' to be effective.

Fyke net would be best probably. If anyone knows where I could buy one made from 1/4" mesh I would love to have that info.

Draining/nuking is not an option. Adding LMB is not an option. 5lb flathead is not an option.
I know that I'll never be 100% rid of them. I just need to keep them under control.

If there's something I haven't thought of toss it out there.
