Can Dust Mites Bite You?

Can Dust Mites Bite You?

If you wake up with raised bumps or itchy skin you may think you have been bitten. Automatically most people think those itchy dots are dust mite bites. 

Dust mites can make your skin itch and give you hives but they cannot bite you. Dust mites can, however, cause allergic reactions. 

Dust Mite Anatomy – Why Dust Mites Can’t Bite You

Dust mites are scavengers by nature. They feed on tiny scales of shed skin.  A dust mite doesn’t have a head. It has a body part known as a gnathosoma. It’s a fusion of the top most body part, legs, and the chelicerae.

The chelicerae are the cutting, piercing and grasping parts. They are too small, too dull, and too weak to remove skin from a living host. That’s why they must be scavengers.

So, as you see, they don’t have a conventional head, mouth or teeth. That’s why dust mites can’t bite you.

Dust mites don’t have a conventional belly or digestion either. Instead, food is digested as it passes through the length of the gut. These digestive enzymes break down the food particle and the spent enzyme is expelled with the fecal pellet.

This protease digestive enzyme is identified as Der p1.  So, that’s why you have bumps on your skin or an itchy rash.

Dust Mite Allergy

Allergy is caused my misidentified proteins. In the case of dust mite allergy, the protein is that troublesome Der p1 from the gut. The fecal pellets and body parts contain this protein.  Basically, your immune system thinks this harmless protein is a germ. 

So, you inhale the protein and your immune system gets to work. Your mast cells get all excited. You produce histamine. Histamine is an inflammatory agent. It’s germ warfare against a germ that doesn’t exist. It’s an allergic reaction.

Dust Mite Allergy Symptoms

Itching, sneezing, watery eyes, wheezing and sneezing are symptoms of dust mite allergy. Allergic urticaria, also known as hives, is also a symptom.

These are itchy, small red bumps or wheals that may look like bug bites. While bug bites are singular, the bumps from hives will be in groups. Hives are a rash.

Do you have trouble thinking clearly in the morning? Feel like you are in a fog for a couple of hours after you get up? You just might have a dust mite allergy.

Dust mite allergy symptoms are worse in the morning.  That’s because your bedroom is the favorite spot in the house for dust mites.

Dust mites love dark, warm, slightly damp places with plenty of food. That describes your bed.  All night you sleep with dust mites. So, you feel terrible when you get up.
