How to get rid of bunnies

I have two large golden retrievers. They came from a multiple national grand champions bloodline in Field Trials and are large dogs, each in-shape and still over 110 lbs. each. They kill a yard with their piss in one season. I decided to give them half the yard covered by turf and fill designed for dogs and half the yard (fenced off) for us to enjoy. The contractor just finished the job on Thursday.

However, there's a damned rabbit, maybe two, that has decided the turf grass is delicious and has already chewed four small holes.

I have a havaheart trap. I have put it out with carrots and apple. Two mornings in a row, the food is gone. Once, the trap didn't close. Last night, the door closed but the carrots and apples were gone.

I had also set up a motion activated sprinkler, sprayed rabbit repellent around the outer edges just off the turf (don't want to spray that on artificial grass, itself) and have motion activated lighting. None of that worked last night to scare off the rabbit(s) and I had another damn chewed spot.

I'm in the city so can't sit outside waiting for it to show up in order to use a .22 rifle and end it's miserable turf chewing existence, so are there other, proven options to getting rid of this (these?) little assholes?
