DS1 has just tested positive for Dust Mite Allergy... he has asthma, severe eczema and nut allergy. He is 17 and lives in a filth pit which I intend to tackle over half term. I have bought the allergy mattress and pillow protectors, an air purifier, a high pitched noise thing, eucalyptus oil, Dettol fabric wash (this might not help the eczema) and some dust mite spray. I've got him a dust mask so he can help with the cleaning. I've also bought Dettol anti bac spray but I'm not sure if that will do anything? Can anyone recommend any other products that can help the forthcoming blitz? Any more spray recommendations? Does the Dettol anti bac spray work on dust mites? Thank you
