We're so sorry to hear that this happened! Our process is designed to reduce the possibility of infestation. While we take great care in protecting the product; some insects can bore their way into tightly sealed packages during transportation and storage. Entrance holes can be very small and difficult to see. Please reach out to us by phone 1-800-248-7310 or via GeneralMills.com so we can report it to our quality team and make it up to you. Thanks.
