Hi, I am looking for a bed protector to reduce or eliminate the dust
mites for my son. Most of them use polyurethane membrane as the
barrier. Is polyurethane a proven safe material for long term use? We
spend 1/3 of our time in the bed and I heard Polyurethane foam should
be avoided for allergy people.

Thanks

Don't know much about polyurethane. But I got my dust mite cover at
Walmart, some sort of plastic like material (king size cover under $50). I
cover the dust mite cover with a sheet that I wash once a week in hot water
to kill the dust mites. I have read that high thread count covers do not
really work on dust mites because the cloth eventually loosens up and allows
the dust mites to go through.

Hi Everyone, the mention of leaving the bed unmade and the mites thus
dying from dehydration is really interesting, I was most interested in
that research report yesterday. It seems that the experiment is
ongoing.
I don't think it would work very well here in Brisbane though, because
the humidity is usually very high.
The best routine here seems to be to sun the bedclothes regularly and
vacuum clean the top of the mattress every couple of days.
A further assistive measure is by keeping the subject as cool as
sensibly possible and wearing of Tshirts as bedclothes.
This kind of routine appears very helpful.
Cheers, Merlin.

Any know if polyurethane a safe for long term use as bed protector? I
heard bad things about polyurethane form but not sure if the
polyurethane membrane is the same thing.

My upholstered furniture isn't made up, but I'm fairly certain a test
would find dust mites in that, too, so I don't really know what leaving
a bed unmade has to do with dust mites.

Check out the products here and see if you can find something without
polyurethane in it. I also know they carry such products at stores
like Target, but don't know what they're made out of.

The allergy against mites has nothing to do with the mites but with their
faeces.
So in many times the most effective way to get rid of the mites is to get
rid of the mattress,carpets and "dust catcher"such as curtains.
An alternative way is the use of chemicals such as
acarosane,phosmethyle,benzylbenzoate.
Investigations made clear that chemicals do not give an satisfying result.
hot washing of the carpets and curtains are also a common way.
Polyurthrane membranes prove safe.

Nylar (pyriproxyfen) juvenile hormone takes out arthropods for up to
nine months/application. Fumigate the house and call it a done deal.
