Rodent proofing the garage

My garage was recently used by some mice as rent-free shelter. I would prefer trying to seal up the garage rather than continue the gruesome battle. Most of the visible cracks and openings I can caulk or otherwise cover up. But the double sliding doors (when closed) have a 1 or 2 inch gap where they meet in the middle, from the floor (where the steel guide is mounted) to the top of the doors. Does anyone know a way to seal this and still have functioning doors? Is there some giant weather stripping made for this purpose, or another solution?

This sounds like a 'larger than normal' gap. A rat supposedly can squeeze through a 1/2" tall opening. What worked for me was a 1 1/2 to 2" tall strip of flexible rubber...maybe called a 'door seal'. It is found near the weatherstripping and comes in a 3" roll..usually in a bubble-pack hanging up, on a card.
The usual practice is to unroll the strip and tack (3/8") it along the bottom of the garage door so it drags slightly on the ground when the door is moved. Use the strip the same way to seal the vertical gap where the doors meet. This should take most of the 'breeze' out of the garage.

Spread moth balls in the ares where rodents may nest. They hate the smell and will simply move out.

Hi Randy - we have a rat problem in our Eichler garage. We're looking into a way to physically block the vermins from entering. Is it possible to post some pictures so we can get an idea of how you did this?
