Okay, I've tried everything I've ever read about to catch these little buggers, short of buying a commercial trap. I had this brilliant idea two days ago and I have caught a total of FOURTEEN meaty little worms in my trap!! WOOT!!!
The first night I tried it, I caught five worms. The second night, I caught NINE for a total of 14 worms in the past two nights.
Here's what I did:
1) I took a dark, opaque container. I used one of those little plastic black salsa bowls you see in restaurants. A small ceramic container would work too and you wouldn't have to weight it down with a rock.
2) I took some large-holed mesh. Like the type you'd see for larger aquarium fish or tulle in a dress. I had some extra floating around from last year's Halloween costume. The netting is about 1/4" spacing. Use the large-holed stuff so the worms can easily crawl in.
4) Put some food in the container. I used slices of frozen scallop. Be a little generous, you want the gluttons to come running, right?
5) Place the container face down in the middle of the netting and secure it. Rubber band, thread, string, whatever.
4) Place it face-down on top of the sand. It doesn't have to be buried, nor does it have to be flush on all sides. Mine was slightly propped on a rock so there was a small gap between the container and the sand.
5) Wait until your lights come on the next day.
