We took a good number of 'chucks when I was growing up. In addition to the havoc they'd wreak on the garden our black Angus cattle were so stupid they'd step in the holes and break their legs so dad was pretty insistent on keeping the chucks out of the cow pastures.
The tactics that worked best were stomping rocks into all of the holes then checking which ones the chucks re-opened. Then you settle yourself comfortably watching one of those holes with an appropriate firearm (we used a .243) and wait.
That was pretty much the entire deal.
