I live a part of North Dakota where to my knowledge ribbon leeches are not real prevalent. I have however found a slough which has quite an abundance of them. I put out some traps using beef liver as bait and so far, all I have been able to catch are small ones. Anyone know any tricks to catching larger ones or is it just a matter of sorting thru them. Would appreciate any input.

Check out YouTube on catching leeches. There's some good info there.

Early leeches can run small. Try again in a week. You will have to sort. For bait I use fish remains after filleting and catch all I need.

This morning trap using beaver liver that was the leeches on the outside, going to be a good pond.

Thanks to all for the help
