Your best option is to shoot the fecker !
If you don't have one beg or borrow one any .177 0r .22 should do the trick but you have to be patient, dusk is best time to plot up & wait.
As Lloydie says remove the food source & they will go elsewhere to look for food.
In the garage have a look around for droppings it will confirm their presence, rats tend to crap in one area unlike mice who crap all over the place.

See how the droppings are grouped together...

Here the rats were coming in in the far corner notice the size of the droppings using the cupboard leg as scale.
Size wise mouse droppings are about the size of a grain of rice but a little fatter, whereas rat droppings are approx 10 x bigger.
The other signs to look for are holes which you can see tooth marks around the edge. & smear marks, this is the natural grease that is on the fur rubbing off & then dirt & dust sticking to it.
This is from mice but you get the same from rats only bigger !
Also look for shredded paper & cardboard which the will use for nesting material.
They can & will chew on wiring & wood on stuff to sharpen their teeth. Known as Gnaw marks again you will see the tooth marks if this is happening.
Rats also require standing water to drink so if you have a pond cover it with mesh if poss.
The chances are that the rats are in burrows underneath the garage if it has a concrete foundation, have a look around for any holes about 3''to 4'' in diameter. Clear any rubbish, over growth, rubble away that is around the garage as well.
ALWAYS ware gloves ! Rat pee carries a nasty virus called Leptospirosis ( known as Weil's disease), it can be passes to humans via rat pee in water via open wounds or scratches...Flu like symptoms but it can kill you !
You can poison them of course but the poison will take about 24 hrs to work & in that time they could go anywhere so you could end up with a dead rat under the floor which you can smell but not get to !
This stuff is available in most DIY stores & supermarkets.

It's a grain treated with poison & should do the trick. Indoor use only ! This is no weaker than the stuff I use at work just smaller amounts.
If you cant do the poison use traps, the best type is the old style snap trap like this...

Must be for rat & not mouse ones as they are much smaller. Bait with peanut butter or meat. Check daily & place against wall so that the trap closes towards the wall.
This mouse was unavailable for comment earlier today.

Making up since 2007, sometimes it's true...Honest...
