Commonly referred to as the mold mite, tyrophagus putrescentiae is a grain storage mite. Increased moisture and humidity are the perfect environment for storage mites to develop. Colonization of the storage mite generally goes unnoticed until your dog or cat develops symptoms. Such mites are often found in dry kibble dog and cat foods as well as boxed pet treats.
