I found mouse or rat dropping in the garage in our 'new' house. I cleaned it up thinking that maybe it was old.
The other day I saw more droppings.
The garage door faces the back alley where our trash cans are. There is about an inch or two of a gap between the floor and the bottom of the garage door.
How do I seal this space to prevent vermin from entering the garage?
Note: the garage door swings up it does not roll up.
