It really depends. If you live in a warm climate, then you need to be sure that there's an even temperature throughout the nest. On the flip side, if you live in a colder climate, you need to keep it warmer. A garage does have the advantage that If your ants require hibernation, the natural temperature of the outdoors during winter will allow them to hibernate really easily.
You also have to make sure there's no vibrations, such as car noises, drilling, or other things like that. This could disturb your colony and be quite counter productive. However, keeping them in the garage is a really great idea if you don't have space elsewhere (or are not allowed to keep them elsewhere, haha) and want them relatively undisturbed. So long as you keep the above things in mind, it should be good!
