You glance up at the living room mantel and notice tiny whitish bugs near a thin trail of dust. A week later, little eggs on wood beams show up, and the trail is wider. Panic sets in. Are termites eating the structure, or are you dealing with another pest? Many homeowners meet wood mites the same way. These mites feed on mold that grows on damp timber, and so, beams and mantels inside a humid house become easy targets.
They do not chew tunnels like termites, but they bring dust, webbing, and an itchy feeling that the whole room is alive. The good news is that wood mites are easier to treat than a full-termite colony. You only need to know what to look for, act fast, and fix the conditions that attract them.
What Do Wood Mites Look Like?
Wood mites are a family of arachnids that are related to spiders. They are approximately half a millimeter in length, so you will only see moving dots until you hold a magnifier. Fresh adults appear clear to pale white. When they feed on mold spores, the gut can take on a gray tint. The body is oval and has eight short legs, unlike insects that carry six. If you have ever spotted clover mites on a sunny wall, think of wood mites as the indoor cousin.
People often confuse wood mite eggs with termite eggs on wood, yet there are clear differences. Termite eggs sit in large hidden clusters guarded by worker termites. Wood mite eggs are single or in small groups stuck to the timber surface. The eggs look like tiny oval pearls, often mixed with a powdery film of mold, and you will not see winged swarmer termites nearby. These details help you decide which treatment path to follow.
Common Signs of Wood Mites in Beams and Mantels
Signs that are mentioned below can be the start of wood mites consuming your beams and mantels:
Fine dust or debris
Mites in beams scrape at mold layers, leaving a light dust that collects on the mantel shelf or floor. Run a white cloth under the beam. If it picks up specks that feel like flour, mold and mites are active.
Eggs on wood
Look for clusters of dots smaller than a pinhead, often at beam joints or along rough saw marks. A flashlight held at an angle makes the eggs shine.
Tiny whitish bugs in motion
Use your phone camera zoom or a hand lens. If the dots crawl instead of hopping, they are likely wood mites, not springtails.
Silk threads or small web patches
Some species spin thin strands for safety while moving across open wood. These strands break easily but may hang in corners.
No hollow sound in the beam
Tap the timber. Termite galleries change the sound to hollow. Wood mites do not chew deep, so the beam stays solid. This clue steers you away from termite treatment.
How to Get Rid of Wood Mites in Beams and Mantels
There are some ways you can get rid of these pesky mites:
Lower humidity first
Wood mites thrive above fifty percent relative humidity. Run a dehumidifier in the room and vent bathrooms or kitchens that add moisture. Dry wood is enemy number one for mites in house timbers.
Vacuum and wipe surfaces
Fit a crevice tool to a shop vac and suck up mites, eggs, and dust. After vacuuming, wipe the beam with a rag dampened in isopropyl alcohol. Alcohol kills on contact and evaporates fast, so the wood does not stay wet.
Apply boric acid or diatomaceous earth
Dust a thin layer along the top side of beams where mites hide. Both powders scratch the mite exoskeleton and cause dehydration. Wear a mask and goggles to keep the fine powder out of your lungs.
Use a mild miticide
If the above steps do not clear the insects within two weeks, buy a labeled indoor miticide that lists wood mites. Follow the label for dwell time and re-treatment. Spot-spraying the beam joint is often enough. Avoid broad spraying that could stain finished wood.
Call a professional for large or stubborn colonies
An experienced pest manager can fog a low-toxicity product into ceiling cavities or apply a residual spray that stays active for months. They will also use moisture meters to find hidden damp spots feeding the infestation.
Repair leaks and improve airflow
Check roof leaks over the ceiling beams and gaps in the chimney area where water can drip on the mantel. Close any openings using exterior-grade caulk. Install vent holes or a small ceiling-mounted fan in rooms that contain timber in large quantities.
Preventing Wood Mites from Returning
To ensure you don’t get the stress of mites ever again in your life, follow these steps:
Seal raw timber
Apply a clear polyurethane or water-based acrylic sealer to exposed beams and mantels. Sealed pores keep moisture from soaking in, which limits mold growth and starves mites.
Keep interior humidity below fifty percent
Install a hygrometer and run the dehumidifier as soon as levels rise. In winter, use bathroom exhaust fans for an extra ten minutes after showers.
Clean beams twice a year
Dusting eliminates the mold spores prior to food. Use a microfiber cloth that is sprayed very lightly with alcohol or a wood-safe cleaner.
Store firewood outside
Firewood carries mites into the house. Bring in only what you will burn that day.
Choose faux beams and mantels
Polyurethane or high-density foam beams, like those in Kustom Beams, are airtight and insect-resistant. They are lighter than solid timber, but appear natural when stained or painted. Installing beams made from lightweight materials is also easier on old ceilings that may not support heavy wood.

When to Repair or Replace Beams and Mantels
Light surface damage from wood mites rarely affects strength, but moisture often leaves stains or slight warping. Inspect each beam after treatment. If you see:
- Deep cracks wider than a quarter inch
- Soft or spongy spots you can dent with a screwdriver
- Dark mold growth that returns after cleaning
then plan a repair. Epoxy wood filler can be used in small cracks. The bigger structure problems require a carpenter who can sister an additional beam to the existing beam or place a steel plate.
When the mantel is decorative and is heavily stained, replacement might be cheaper than refinishing. This is faux beam and mantel glowing. They appear exactly like reclaimed oak or fir but are unable to invite wood mites.
Conclusion: Protect Your Beams from Wood Mites
Wood mites may be small, but they signal excess moisture and mold on prized beams and mantels. The keys to fast relief are clear: confirm the pest, dry the wood, clean away eggs on wood, and use targeted products that answer the question of how to get rid of mites. Once the beams are clear, sealing the surface and controlling humidity keep mites in house timbers from returning.
If your current beams have suffered repeated infestations or you want a fresh look without future pest worries, consider custom faux beams and mantels from Kustom Beams. They offer durable, pest-resistant designs that stay beautiful year after year. Call today to learn how a faux timber upgrade can protect your living space and keep tiny whitish bugs out for good.
Frequently Asked Questions
How do you know if wood has mites?
If you see tiny white or brown specks crawling on wood or notice fine, dusty powder nearby, you probably have wood mites.
Are wood mites and termites the same thing?
No, wood mites aren’t the same as termites—termites damage wood, while wood mites mostly eat mold and don’t harm structures.
Can wood mites infest a house?
Yes, wood mites can infest your home, especially wooden furniture or floors, and might lead to mold if not dealt with.
What smell do wood mites hate?
Wood mites hate strong smells like cedar, eucalyptus, clove, and tea tree oil—these scents help keep them away naturally.
How to stop mites from coming back?
To keep mites from coming back, wash everything in hot water, vacuum often with a HEPA filter, and use protective covers on your bed.
How do you get rid of wood mites?
To get rid of wood mites, clean the area well, lower the humidity, and use treatments like boric acid or vinegar; for big infestations, call a pro.
