You’ve probably seen them hiding under beds or lurking around floorboards. They’re furry and quiet, but they don’t eat carrots. What are they? Dust bunnies, of course!

Why are they called “dust bunnies”? No one knows for sure, but it might have something to do with the fact that they’re fluffy, quiet and tend to multiply rapidly!

Usually hanging out under furniture or other areas that are hard to reach with a vacuum, broom or duster, dust bunnies are balls of dust and other materials that tend to be held together with static electricity. If static charges build up, dust bunnies can become attracted to each other, resulting in large “super” dust bunnies!

But what exactly is dust? In the air, dust consists of tiny particles of soil lifted by the wind, as well as particles of pollution and microscopic debris from volcanic eruptions around the world.

In your home, atmospheric dust combines with plant pollen, animal hair, human hair and dead skin, clothing fibers and other tiny particles to form dust bunnies when static electricity binds these items together.

Although you might think that dust bunnies — other than being dirty — are mainly harmless, they actually can cause a variety of problems. If they find their way into or around electronics, they can clog vents and cause overheating. They can also clog vacuums and air vents if they get too large.

More troublesome, though, is their potential effect on your health. The organic matter found in dust bunnies, such as human and animal hair and dead skin, is the perfect source of “food” for house-dust mites.

House-dust mites exist in all climates, even at high altitudes. One gram of dust can house almost 200 house-dust mites. Unfortunately, house-dust mites produce allergens that can trigger asthma and contribute to a variety of respiratory problems.

So how do you get rid of house-dust mites? Clean!

Regular dusting and vacuuming, as well as cleaning soft materials like pillows and bedding, can substantially reduce the population of house-dust mites and thereby reduce their negative health effects.

    • Hi, Meredith/MC! We’re glad you liked the video for this Wonder! We think it was funny how the person who animated the video made the vacuum cleaner look like a villain! :-)

  3. If you go to google, type in dust mites and you can see were they are on your body or in your hair. I saw this movie it was a very awesome one and I really can’t remember the name of it. I saw this one part when a guy sprayed water and the room was very dusty and a lady swept the dust off the ground. That is the only thing I have to say.

    • That sound like an interesting movie, Joel! Thanks for sharing your comment with everyone in Wonderopolis today! :-)

  6. Wonderopolis I chose hygiene to learn about. Did you know my class chooses a category for a week? I chose hygiene and the first question was what is a dust bunny? It was so funny. My favorite part was when a dust bunny got in the doll’s hair. Thanks for making learning fun.

    • Hey there, Wonder Friend Nic! We are so glad you and your Wonder classmates are choosing a category to Wonder about each week! How COOL! We hope you learned something new today, and we’re glad the Wonder video made you laugh! :)
