Thank you for your inquiry.
I agree with you that there is nothing in the literature on the topic of hoarding and dust mite allergy. At least I am unaware of any such study and was not able to find one on a literature search. However, it is clear that the greater the dust mite load, the greater the symptoms in allergic individuals, and diminishing dust mite exposure is clearly an effective means to improve symptoms. It is intuitive that hoarding may create a more hospitable environment for dust mite residence and growth, but I am not aware of any data on the subject.
Thank you again for your inquiry and we hope this response is helpful to you.
