Well, I was hoping for one or three useful suggestions from the many experienced superintendents who lurk on this site. But this has not been a total waste- I now know who Gary P. Nunn is and have been amused by the somewhat uninspired attempts at humor.
Our superintendent is blessed with having earned a great reputation over many years among his peers, the membership, and most important, his boss, the owner. Our situation is such that at many other places, he might be shown the door.
Just this morning one of his more experienced employees told me that they've tried spraying chemicals to encourage the critters to leave, but they seem to be outsmarting their efforts by moving and digging on another part of the course. And when the effects wear out, they simply return.
Trapping apparently has not worked. I did some digging on the internet prior to starting this thread and found a variety of short term, small area recommendations- cayenne pepper, predator urine, various oils. There are professionals who claim results, but these likely involve lethal means at night, which would likely pose problems with some surrounding homeowners.
Nevertheless, I suggested a late night roundup with a Calcutta, 18 three-man teams, infrared and night-vision equipment, nets, baseball bats, one crossbow per team, $100 bounty/'dillo out of the maintenance budget, followed a few days after the eradication with a chili cook-off, adult beverages, country music and the awards ceremony. Too much liability, I suppose.
