Dust Mites: More Than just Allergies

Invisible to the naked eye but present in our daily lives,dust mites are microscopic creatures that live in our mattresses,on our skin,and even on our cheese! Frequently enough linked to allergies or itching,ther’s more to these arachnids than their bad reputation.

1/ Mites are insects

False. like spiders and scorpions, mites are arachnids and have eight legs. Around 50,000 species have been identified, but their diversity could be over a million.

True. It’s not pleasant to think about, but millions of tiny creatures live on our skin. Feeding on our sebum, small mites (around 0.3 millimeters long) of the species Demodex folliculorum and demodex brevis live in our sebaceous glands and
