Things You'll Need
Instructions
Wrap an old kitchen towel around a length of board. The towel will provide traction for the chipmunk.
Set the board into the window well at an angle, creating a bridge that allows the chipmunk to climb out. Be careful not to hit the chipmunk with the board as you place it in the window well.
Leave the immediate area for at least 24 hours. The chipmunk might not use the board unless it is confident that no one is around.
