Each spring and fall, the sunny side of many DC homes sees an invasion of clover mite crawls across siding. These clover mites are a persistent turf pest and a nuisance indoors. Better Termite & Pest Control is a local pest control company with decades of DC metro experience.
Here are a few clover mite facts to help you understand the threat.
A clover mite is a brick-red arachnid no bigger than a pinhead. They look bright red and use a pair of front legs like antennae. Although clover mites feed on plant leaves, they cause only cosmetic marks. This is one of the main types of mites reported in turf.
Per UF/IFAS Featured Creatures, they develop through four stages before adulthood. They reproduce by parthenogenesis, and each mite lays about 70 eggs in sunny cracks and crevices on warm walls.
This clover mite life cycle lasts from egg through adult clover mite in a few weeks. They overwinter behind flashing, bark, or siding. A clover mite infestation shows up as masses of little red bugs along the perimeter of the house.
In my years as a licensed technician with Better Termite & Pest Control, I’ve seen key conditions that attract clover mites. They are a nuisance on warm sunny walls. Moisture, dense vegetation, and yard care all play a role. Like millipedes, clover mites thrive in humidity (see Millipedes).
A single clover mite can cross several siding panels in minutes when conditions suit it.
Clover mites are attracted to sun-warmed brick and siding. Urban heat island spots heat walls faster, so mites go to warm areas. According to the National Weather Service, mid-Atlantic wall temps often hit their sweet spot by mid-morning.
Healthy clover in turf and clover ground covers offer a food source. Clover mites eat sap from clover, grass, and ornamental plants. New or heavily fertilised lawns with lush turf push up numbers. University of Maryland Extension notes that thick thatch by walls creates humid pockets ideal for mites.
A study by Virginia Tech Publications lists key grasses and clover that mites favor.

Spring rain followed by warm, dry days drives mites from wet turf to sunlit walls. Moisture under ground covers and near foundation cracks fuels high humidity. Clover mites live in small crevices before they crawl indoors.
Leaves from ivy or ornamental plants can touch siding and form a bridge for mites. They slip through cracks around windows, door frames, and weep holes. Sealing these entry points cuts off their path into your home.
The DC area has lush turf on clay loams and warm, humid springs. Construction boom sites with new sod flush to brick drive infestations. Strong tall fescue lawns and clover mixes can multiply pest populations fast.
Seasonal peaks send each clover mite to seek fresh crevices on sunlit walls.
Every clover mite in the DC metro finds plenty of lush turf and warm walls to thrive.
Activity picks up in March–May and again in September–November. Warm days above 50°F trigger new activity after eggs overwinter. I track timing by checking south-facing walls after early spring rainfall.
Dark pavement and roof materials amplify sun’s heat, pushing mites to cooler north walls later in the day. These pests search walls by 2 PM when west facades get the hottest.
Lawn fertilization often exceeds recommendations, boosting turf nitrogen. Over-fertilized grass and clover blends near foundations provide ample food and humidity for mite growth. Adjust soil tests and water deeply to reduce pockets.
Small red bugs along window sills, baseboards, and at wallpaper seams spell trouble. If you find clover mites on light curtains, you may see streaks. When clover mites leave behind a red stain on fabrics or walls, don’t scrub or you spread pigment.
If you spot a lone clover mite in a corner, expect more to follow soon.
These tiny red arachnids move in clusters across sills. When they crawl indoors, vacuum them up. Mites don’t bite humans or pets and die quickly away from sunlight.
This tackles mites in your home quickly.
Crushing mites can smear a red stain on drywall or fabrics. These marks are carotenoid pigment, not blood. Cleaning with mild soap and water lifts the mark.
Clover mites are a nuisance but not harmful to people, pets, or structures. They don’t bite and carry no diseases. Any damage is cosmetic, mainly slight turf stippling that mimics drought.
It’s key to know about clover mites: unlike spiders, clover mites do not bite or tunnel into walls.
Although clover mites can swarm, they don’t harm structures.
Clover mite identification hinges on eight legs and a pair of antenna-like front legs.
Clover mites are tiny compared to red bugs or ticks. You can identify clover mites by their size and the long front leg pairs. Unlike spiders, they never spin webs.
The best way to get rid of clover mites is a targeted barrier treatment by a registered technician. Start by vacuuming indoors and sealing cracks around the perimeter of the house.
Knocking down a clover mite with soap spray is less effective than vacuuming.
When dealing with clover mites, never crush them to avoid red stains.
Vacuum visible mites in crevices, then discard the bag. Light soap sprays on window tracks also knock down survivors. Remember, mites leave a red stain if crushed. For more tips on dealing with clover mites, see our How to Get Rid of Spiders: Easy Steps for Homeowners.
Our registered technicians treat the perimeter with an EPA approved non-repellent product. This step kills mites as they crawl from turf to walls. Usually one or two treatments bring a clover mite infestation under control.
Better Termite & Pest Control pest control services use targeted miticides at around the perimeter to stop mites before they enter.
Prevent clover mites from coming back with these prevention tips. Proper clover mite prevention starts with removing vegetation that touches walls. A dry, gravel buffer keeps clover mites at bay. Per MU Extension, an 18–24 in. barrier works best.
Seeing a clover mite near a window means it used that spot to slip inside.
Use high-quality silicone caulk to seal cracks and entry points around windows and foundation. This step cuts off major routes for mites crawling in.
Keep vegetation at least 2 feet from walls. Replace clover ground cover with ornamental plants that mites avoid. This landscape tweak can reduce populations long-term.
Tracking a clover mite surge keeps your home free of cascading red stains. If clover mites in your home concern you, we’re ready to help.

Clover mites appear when sunny walls heat up and lawns have lush clover or grass. Moisture followed by warm, dry days triggers them to move inside.
They’re drawn to sun-warmed masonry, cracks around windows and doors, and nearby ground covers that touch walls.
Non-repellent perimeter treatments applied by a licensed technician work best. DIY soap sprays help indoors but won’t stop new mites outside.
Left untreated, a surge can last a few weeks until hot summer or cold weather sends them into dormancy.
They do not bite humans or pets. Clover mites don’t have the mouth parts to pierce skin.
They only cause minor spotting on turf; they feed on plant juices but rarely harm overall plant health.
