hi, pretty much what's been said above, i use a pump, can clear 100 worms in an hour on a good day, just need the right nak and you're there !
check where you intent to dig, it wants to be sand, silty sand is ok too, go as deep as you'd expect to find the worms normally, if there's small gravel etc you'll be ok, but if there's pebbles, you'll poss struggle, ok with the odd one's of course!!! the sand also wants to be fairly compact, loose, dryish sand won't pump aswell as more dense damp / wet sand,
how do they work and how to use ?
they work just like a syringe, it will vary from tide to tide on where the worms are, sometimes they're deep, other times right at the surface, the other night we coulda got loads with their asses poking out !
usually you place the pump a few inches away from the hole, at around 30 degrees from upright, pull the handle and push the shaft about 8-12" down toward the hole, pump the sand out... hopefully a worm, if you find they're not coming, then try closer too, or further back from the hole, and different depths,
obviously you'll need to dig where there are casts, the pumps don't work very well for blow lug which are more often found in just a few inches of sand on rock base etc.
