I Have A Very Sensinsitive Friend That Can Not Find

I have a very sensinsitive friend that can not find a place to live till she finds a sterile place to live. she could stay at my home but she is ilergict to dust mites and other airborne stuff. she has suggested a Rugdocker cleaner and put water mixture with Dust Mite-s to help her with her algeries . I have birds but I can remove them them the house to my motorhome. she segests I by 2 # of this chemical and mix it 1/2 parts. mixed in the rug cleaner. I can only do so much area and she knows that. she needs a place to stay for a few months. Any sugestions. thanks Lissa Lamdin
