Hi, thanks for reaching out. We are disappointed to learn about your experience with our RID-X 19.6 oz. Professional Powder. Complaints of this nature are very rare since we maintain a strict quality control. However, storage factors and warehousing are outside our control, and it may be possible for a product to be subject to infestation. The damage occurs when RID-X is stocked along side products which may be infested, like cereals, flour, or bird seed. Rather than being the source of infestation, Rid-X can become infested by these other products. We'd like to speak with you further regarding the matter. Please call 1-800-228-4722 between 9:00-5:00 EST (Monday-Friday) or send us an email to us at consumercare_usa@reckitt.com with the following case number, RB0002055191, and we would be more than happy to assist you. Sincerely, your RID-X team.
