What Are Clover Mites? Everything Texas Homeowners Need to Know

Clover mites (Bryobia praetiosa) are tiny arachnids that show up in large numbers during the cooler months of spring and fall. You might notice them as reddish specks crawling around window sills or walls, especially on the sunny side of your home.

They’re about the size of a pinhead—less than a millimeter long—and have an oval shape with a reddish-brown or greenish tint. One of their more noticeable features is their front legs, which are longer than the others and often mistaken for antennae.

These mites reproduce without mating. Every single one is female and capable of laying up to 70 eggs in sheltered spots like cracks in walls, under siding, or in tree bark. When the temperature climbs above 45°F, those eggs hatch, and activity picks up fast.

What Attracts Clover Mites?

There are a few common reasons these mites show up around homes. The biggest factor is how the landscaping is managed. Well-maintained, fertilized lawns with dense ground cover are exactly what they’re looking for.

Here’s what tends to draw them in:

• Regularly fertilized grass, especially near the home.
• Clover, ivy, and other low-growing plants.
• Sunlit areas near windows and walls.
• Cracks and gaps around the foundation or siding.

Once outdoor conditions shift—whether it’s getting too hot, too dry, or too cold—they’ll start looking for ways indoors.

Clover Mites Indoors vs. Outdoors: What Changes and Why It Matters

Clover mites behave differently depending on where they are, and understanding that difference helps you know what you’re really dealing with—and how to get ahead of them.

Outdoors

This is where they thrive. Clover mites feed on plant sap from grass, clover, and other ground cover. You’ll usually find them:

• On sun-facing walls, patios, and siding.
• Nestled in dense, fertilized grass or shrubs.
• Around window frames and foundation cracks.

They don’t cause visible damage to plants, but large numbers can be an eyesore. And once the weather changes—getting too hot, too dry, or too cold—they start looking for shelter.

Indoors

Once inside, they’re not feeding or nesting. They’re simply trying to survive. The indoor environment confuses them, which is why they:

• Congregate around sunny windows and walls.
• Appear sluggish and die off quickly without access to plants.
• Leave red stains when crushed on walls, curtains, or furniture.

They can’t breed indoors. So, while their presence is frustrating, the good news is they aren’t establishing a population inside your home. It’s a temporary intrusion—not a full invasion.

Do Clover Mites Bite?

No. Clover mites don’t bite humans or animals, and they don’t spread disease. They’re not a threat to your health or safety.

That said, they can be frustrating. If crushed, they leave behind red stains due to their body pigments. These marks can be difficult to remove from walls, curtains, or furniture. While they won’t hurt you, they can definitely make a mess.

Clover Mites vs. Chiggers: What’s Crawling on You?

They’re both tiny. They’re both red. They both show up around the same time of year. But clover mites and chiggers aren’t the same—and confusing the two can send you down the wrong path when it comes to treatment and prevention.

Here’s how they compare, side by side.

Appearance

• Clover Mites: Reddish-brown or greenish, oval-shaped, with eight legs. Their front pair of legs is much longer than the rest and is often mistaken for antennae.
• Chiggers: Bright red and rounder in shape. They’re usually too small to see clearly without magnification. Larval stage has six legs.

Where You’ll Find Them

• Clover Mites: Outdoors in grass, clover, and ornamental plants. Indoors near sunny windows or on walls.
• Chiggers: Tall grass, weeds, brush, and wooded areas—especially in humid conditions.

Behavior

• Clover Mites: Feed on plant juices. Harmless to humans. Don’t bite, sting, or burrow.
• Chiggers: Larvae attach to human skin and inject enzymes that cause itching, irritation, and red welts—usually around tight clothing areas.

Biting or Irritation

• Clover Mites: Do not bite humans or pets.
• Chiggers: Absolutely do. They cause intense itching that can last for days.

Indoors?

• Clover Mites: Common indoors during seasonal transitions when they’re looking for shelter.
• Chiggers: Rarely enter homes. If they do, it’s typically via clothing or gear, and they don’t survive long.

The Bottom Line?
If you’re dealing with itchy bites, it’s not clover mites. Look to chiggers—or another biting pest. But if you’re seeing tiny red bugs near windows or crawling up your siding without any bites or rashes, it’s likely clover mites making themselves a little too comfortable.

How to Get Rid of Clover Mites

If you’re seeing them indoors, the first step is cutting off their entry points. Because of their size, they can slip through tiny openings.

Here are the most effective ways to control them:

• Seal cracks and gaps around doors, windows, and the foundation with silicone caulk.
• Remove vegetation directly against the home—consider a 2–3 foot plant-free strip around the base of the house.
• Reduce fertilizer use near the building, especially in early spring and fall.
• Use perimeter treatments outdoors with products labeled for mite control.
• Vacuum indoors instead of wiping or crushing them to avoid staining.

Persistent or large-scale infestations may call for professional pest control, especially if they keep returning season after season.

How to Get Rid of Clover Mites Naturally

If you prefer to avoid chemical treatments, there are a few low-impact options that can help discourage clover mites without introducing harsh products into your space.

These methods include:

• Peppermint oil spray: Mix a few drops with water and apply near windows, doors, and baseboards. The strong scent helps repel mites.
• Diatomaceous earth: Sprinkle around known entry points. It’s safe for people and pets but abrasive to mites.
• Vacuum regularly: Focus on windowsills, corners, and other bright indoor areas where mites tend to gather.
• Limit plant growth indoors, especially near windows where mites might enter from outside.

With consistent attention, it’s possible to manage clover mites without turning your home into a treatment zone. Staying proactive with sealing, trimming, and light deterrents goes a long way.
