How to kill crayfish?

[insanity]

OK now i laughed at our land lord for wanting to poison the craw fish living in his mothers yard at first.(So go ahead yall laugh it up to! )
But now there killing plants in my garden by tunneling up beside them exposing the roots.So I'm not laughing any more. The crayfish and the darn moles have gotta go!
They both are recking havoc with our lawn more blades as well.Anyone ever seen a poison that would kill craw fish? I really hate to use poison since the ground water is so high here but i don't no what else to do.We are talking 2 acres of yards.So id be just dropping something down each hole as we find it.
Wondering if dish soap would run them out of the garden areas? Or if sprayed all over the garden would they leave the hole area?

Yes i said crayfish in the yard. The ground water is very high here only inches below the surface,most of the time.So they are happy to tunnel around the yard with no other streams or ponds nearby.They don't have the amount of tail meat that creek dwelling craw fish have and they live in nothing but mud.So no I'm not eating them.

As for the moles I'm rigging up a barrel to hold water,plumbed to a water hose.So i can pull it behind my mower and just fill there holes as i find them.If you trap them with the water they will come running up out of the ground to keep from drowning.Then ya can dispatch the little darlings.They tend to stay confined to the higher ground and the crayfish to the lower.So we are just mowing dirt every where we go.

Ya no of anyway to catch them out of the ground? (Read above no water source other wise.)
Used a hot dog a piece of string to amuse the kids once.But it doesn't work to well.These guys are eating size wouldn't make very good fish bait.Eating size heads anyway.Theres very little tail meat (do to crawling,not swimming id guess) and thats the only part i eat.But I'm not eating these regardless.Lord noes whats in the ground here.We are only 5 miles or so from the local land fill.

i dont know about killing them in the yard, but if you got kids, give them some string with a piece of hot dog on it, and let them "fish"the holes, theyll be busy for hours lol

I was told (can't vouch for it) that they hate lime. You could put some down their holes and if it doesn't kill them maybe they will at least leave your garden alone! Worth a try! Rita

"Take chicken wire (mesh size determines what size crawfish you want). Cut lenght from a 36" roll that will give you 18" diameter tube. Stitch up the long side. Flatten the tube where it is 8" high. Hang a 3" homemade snap (made from a clothes hanger) dead center to hang your bait.

Stitch up the middle of one end (going from the center to the edge) leaving about 1.5" on each end. Invert these "holes" to the inside to make two cones. Use a long-necked bottle to help round them out. Don't let the trap get too flattened. Make some wire hooks for the other end to hold it closed."
