The main plant extract in allergy control products comes from the Papaya plant and it's properties have been known about for years.
There is only one product which, as far as I'm aware, will not only eliminate dust mites but remain active for at least a year, unfortunately, just as a group of c/c were being introduced to the product, about 8 years ago, the UK distribution was taken over and the product was only being offered to anyone prepared to invest a substantial amount of money, to become distributors.
The product is still out there and it really has fantastic qualities, with very wide applications, eg, it can be introduced at the manufacturing stage, into underwear, socks, etc, to control odour. All of the attendees at the meeting in Sheffield were given a pair of treated socks.
The product is Aegis and one of you might just get very rich by looking into the opportunities it could offer..............at 62 I've been slowly building other interests for an easier life
