DD1 had a blood test done years ago & has allergies to dust mites & mould. I've actually never thought about the mites til now. Mould was always the big trigger for her asthma, but mites are probably not helping.

We have no carpet in our house now, but her asthma was shocking out at my parents house out of town.. Basically a shed... I'd actually completely forgotten about it.

I have a vax & have always cleaned my carpets every 6 months. I've got no other suggestions, but will be keeping my eye on this thread & paying more attention when she flares up again.
