I recommend writing a CustomException class instead. So everytime you see a third-party error, catch it and throw a new CustomException() (Without arguments, otherwise you may carry some bad third-party classes/exceptions in your codebase). And don't forget to catch CustomException at strategic places too, so you can actually throw a new CustomException().
