wireworm trap

This picture shows my wireworm trap in action.  I stuck a number of full-grown carrots throughout my raised bed.  I pull them up and check for takers.  Wireworms are not very fast.  In fact, they often "play stick" when pulled up in the trap.  I usually take my time and cut them in half with an old plant description stick. 

I felt silly using good carrots as bait -- but they have lasted a couple of weeks already and don't show much sign of decay.  I hear you can bury potatoes too but I haven't tried it yet.
