The lesson here is important. People who are allergic to house dust mites may also be allergic to storage mites commonly found living in poorly stored grain. Some scientists prefer to call all these mites 'domestic mites' as they can be found in our homes and work places if the conditions are right. It's best to be safe and not encourage domestic mites in food or the home environment.
