Who's had experience remediating worms on golf courses? What can you use today?
You could try carbaryl, commonly sold under the trade name Sevin.
I'll second the effectiveness of Sevin SL. The castings can be a nuisance, especially on wet mornings if the greens aren't whipped.
Localized areas can simply be soaped up (any sort of citrus based soap like Lemon Dish Detergent - the citric acid closes the breathing pores of the insect and forces it to the surface).
Tiger Bernhardt saw me do this with Mole Crickets this past winter.
"Old Henry went past the pet shop which was never open, into the park which was never closed, and the park was full of a very smooth, clean, green grass. So Henry took off all his clothes and began rubbing his flesh into the wet, clean, green grass. He accompanied himself with a little tune - it went like this....
"Beneath the ground the dirty brown writhing things called worms interpreted the pitter patter from above as rainfall. Rainfall in worm world means two things, mating and bath time. Both of these experiences were thouroughly enjoyable to the worm colony. Within seconds the entire surface of the park was a mass of dirty, brown, soggy, writhing forms. He was still pleased, old Henry and he began whistling a tune this time to accompany himself......
"Jerusalem Boogie to us perhaps, but to the birds it meant that supper was ready...."
"Walking across the sitting room...."
