Any suggestions for evicting a raccoon and maybe up to 6 kits from a garage? [View all]

Let me begin by saying this has been an ongoing problem at my mothers house for a couple of weeks now and I think we are going to call in a professional. She left the unattached one-car garage door open one night and has had at least one raccoon in it now for two weeks. At least we think it is a raccoon?

Guy from the city came out and put two traps that were supposed to be raccoon sized, but traps had the food removed and the trap door snapped shut which kind of indicates the raccoon may be large enough to get the food, trip the door, but the door is coming down on its back and not locking the critter in. Which means it must be a heck of a big raccoon. Or something? The guy from the city said he isn't coming back.

Everyone we know has had some suggestions. None of which sounded good to me. The footprints this critter is leaving look to be about the same size as the footprints my German shepherd/border collie mix who weighs about a hundred pounds has. So I know this critter has to be pretty good size. Whatever it is.

Reason I think there may be some kits involved is because it is starting to smell like a zoo in her garage now.

Thanks in advance for any suggestions or wishes of good luck.
