Its easily done, just as mentioned check the trap in the hole first in the closed position to ensure it will fit and fire free of obstruction. Scrape a bed out for it, set the fenn with the safety on, ensure its firm in the ground, use fine soil to build up either side of trap then cover the pan, and remove the safety... I bend the pan up on traps slightly, when I'm sticking them in rabbit holes.. You can also block all the holes if wanted like has been said then trap the ones that have been cleared..
