Clover Mites

Clover mites are tiny, reddish-brown pests that can become a nuisance for homeowners, especially in early spring and fall. These mites, which are about the size of a pinhead, thrive in heavily vegetated areas and are often found in lawns and gardens. While they are harmless to humans and pets—they do not bite or transmit diseases—clover mites can invade homes in large numbers, causing concern for residents.

What Are Clover Mites?

Clover mites (scientific name: Bryobia praetiosa) are arachnids, closely related to spiders and ticks. They primarily feed on plants, including clover (hence their name), grass, and various flowers. In large numbers, they can cause damage to your lawn and garden by sucking the sap from grass and other plants. They become a problem when they enter homes through cracks and small openings, especially around windows, doors, and siding.

Where Do Clover Mites Come From?

Clover mites are most commonly found outdoors in areas with lush vegetation. They thrive in well-fertilized lawns and can reproduce rapidly, particularly in early spring when temperatures are cooler. When the weather becomes too hot or too cold, clover mites often seek shelter indoors, leading to infestations inside homes and businesses.

Signs of a Clover Mite Infestation

Visible Mites: You may see tiny red or brown dots moving around window sills, walls, or floors, especially in sun-exposed areas of your home.
Stains: When crushed, clover mites leave behind reddish stains on walls, furniture, or curtains.
Outdoor Presence: If you notice large numbers of these pests on the exterior walls of your home, particularly around windows, you may have an infestation on the way.

Why Are Clover Mites a Problem?

Though they do not pose direct health risks, clover mites can be an annoyance because of their sheer numbers. Once they invade your home, they can be difficult to remove, and the stains they leave behind can damage surfaces. Clover mites can also be a sign of over-fertilization in your lawn, which may lead to other pest problems.

How to Prevent Clover Mites from Entering Your Home

Seal Cracks and Gaps: Use caulk or sealant to close gaps around windows, doors, and foundations.
Maintain Vegetation: Keep plants and grass trimmed away from your home's foundation. Creating a vegetation-free zone around your home can act as a barrier.
Reduce Fertilization: Over-fertilizing your lawn can attract clover mites, so use fertilizers in moderation.
Professional Pest Control: Hiring a pest control service ensures that your home is properly treated for clover mites, both indoors and outdoors.
