You may be able to use a repellent to keep raccoons out of areas where they might cause damage and you will need to make sure that you keep them clear of any objects and surfaces that might be too expensive for damage or if you simply want them to be off these surfaces. You may be able to sprinkle barrier repellent to keep them off these areas, you can spray liquid repellents in order to keep them off of trashcans and birdfeeders for more specific protection. Raccoons can be however pretty resistant so it might take weeks before these repellents will officially be effective.
