Just found out I'm allergic to dust mites!  The main species are cosmopolitan pyroglphids but I call them House dust mites. 
I've always heard of them but don't know much about them.
they are so gross - they feed on skin flakes from people and pets, and sometimes mold. 
That does sound nasty, can people see them? Or are they microscopic?
they are so small and have translucent bodies so they are barely visible to most people 
Is there a way to get rid of them or reduce them? I'm wondering if they cause some of my family's allergy problems
Allergies are so bad and can cause red, itchy eyes and rashes, sneezing, face swelling - is that what your family has?.  So hard to treat them.
