You woke up in the morning after an uneventful sleep, and notice a few bumps of bite marks on your arm. You’ve heard of pests that may be invading your space and you’re wondering if dust mites have been biting you while you’re asleep.

So, do dust mites bite humans?

The short answer is no. Dust mites, as horrendous as they may seem, do not bite humans.

What Does Dust Mites Feed On?

While dust mites don’t feed on humans’ flesh nor suck their blood, these microscopic creatures chew on the dead skin cells that you’ve been shedding on all day. On average, an individual will shed about 1 million skin cells in 24 hours.

That’s ample food supply to grow colonies of dust mites in your home.

The bed is often a common suspect of dust mite infestation as an individual spends an average of 7 hours sleeping and shedding dead skin cells on it daily. Carpets, rugs, upholstery, sofas and other items in your home that you interact with may also gather dead skin cells to fuel the growth of dust mites.

Dust mites have a rapid growth rate when they are fed sufficiently and live in an environment that is conducive. These tiny creatures prefer spaces that are humid (70%-80% RH) and moderately warm temperatures (20 – 25 degrees Celcius).

If Dust Mites Don’t Bite Humans, What’s Causing The Bite Marks?

If you’ve been getting bite marks and bloodstain on the lines for a few nights, you may have some unwanted visitors in your bedroom. These visitors are not dust mites, as we’ve clarified on that. Chances are, you’re bitten by the nocturnal bed bugs, which unlike dust mites, feed on human blood.

Like dust mites, bed bugs share the same preference of the surrounding environment. A warm and humid room attracts bed bugs. However, bed bugs don’t hide in the mattress. They are often found in cracks and wooden crevices.

Bed bugs are much larger than dust mites and are visible when you’re paying attention to spotting one. These nocturnal bloodsuckers have the appearance of a flat apple seed. They are brownish and belongs to the insect family.

Often, you won’t waken up by bed bugs bite as they inject an anticoagulant into the wound. The anticoagulant explains the occasional bloodstain is it prevent blood from clotting when the bedbugs are feasting.

Bed bugs bites are often treated with anti-itch creams and calamine lotion. In some cases, pain reliever is prescribed and anti-histamine medicines are used.

Are Dust Mites Harmless Then?

Just because dust mites don’t bite, it doesn’t mean that they are completely harmless. Far from it, dust mites are often considered more dangerous than bed bugs. This is due to the excretion of dust mites, which contain a form of protein that triggers allergic reactions in some individuals.

Both children and adults can exhibit allergy symptoms to dust mites. Here are some of the tell-tale signs.

  • Itchy, teary eyes.
  • Runny nose.
  • Coughing.
  • Sneezing
  • Skin rashes.
  • Nasal inflammation.

It is important to get these symptoms treated, especially for children, as it could lead to asthma.

When you’re suffering from the symptoms, daily activities can be affected. Nasal inflammation can cause distress amongst children and may affect their sleep. Without laying a single bite, the complications caused by dust mites are more severe and long-lasting.

Getting Rid Of Dust Mites

Regardless of whether dust mites are biting humans, they are unwelcomed in your home, especially if you or your family are showing signs of allergy. While it’s impossible to eliminate every single dust mite, you can reduce the population to a harmless level.

The good news is, dust mites are fragile creatures. Dust mite’s growth are stunted when the humidity shifted from their preferred range. They are easily killed in temperature exceeding 55 Degree Celcius.  Here are a few quick tips to help you remove dust mites from your home.

Wash beddings at least once a week. You’ll want to turn up the temperature in the washer or dryer to kill dust mites that are present in the bedsheets or pillowcases. You’ll want to pay more attention to the mattress, as you may have more dust mites hiding in it.  Using a UV vacuum cleaner with powerful suction helps to neutralize dust mites in your bed.

You’ll also want to clean carpets, rugs, and upholstery which are perfect hiding places for dust mites. Consider using certain types of essential oils or natural dust mite sprays. These will reduce the growth of dust mites in your home.
