Clover mites are common, tiny arachnids that often become unwelcome guests in homes. These minuscule creatures are frequently mistaken for other small insects due to their size and rapid movement. While they do not pose a health risk to humans or pets, understanding these small pests helps in managing their appearance indoors.
Understanding Their Size and Appearance
Clover mites (Bryobia praetiosa) are plant-eating mites that are incredibly small. Adult clover mites measure between 0.75 and 0.85 millimeters long, equivalent to 1/30th of an inch. This makes them smaller than a pinhead, often appearing as tiny moving specks to the naked eye.
Their bodies are oval-shaped and can range in color from reddish-brown to dark greenish-brown, sometimes appearing olive or pale orange, especially after feeding. Like other arachnids, clover mites possess eight legs. Their front pair of legs are considerably longer than the others and often extend forward, leading them to be mistakenly identified as antennae.
Where Clover Mites Are Found
Clover mites primarily inhabit outdoor environments, thriving in lush vegetation such as lawns, gardens, and well-fertilized turf. They feed on a wide variety of plants, including clover, grasses, and ornamental flowers. These mites are found across every continent except Antarctica.
As temperatures fluctuate, particularly during late spring, early summer, and fall, clover mites may seek shelter, warmth, or new food sources indoors. They gain entry into homes through small cracks and openings around window frames, doors, and foundations. Their small size makes screens ineffective at keeping them out.
Why Clover Mites Become a Nuisance
Clover mites become a nuisance primarily due to their tendency to invade homes in large numbers. While they do not bite humans or pets, carry diseases, or cause structural damage to homes, their sheer presence can be unsettling. The main problem they present is the reddish-brown stains they leave behind when crushed.
These stains are not blood but rather the mites’ body pigments, and they can be difficult to remove from surfaces like walls, carpets, and upholstery. Attempting to wipe them away can inadvertently create more mess. Their rapid reproduction rate, with females laying approximately 70 eggs at a time, contributes to their growing populations indoors.
Managing Clover Mite Presence
Managing clover mite presence involves both preventative measures and direct control strategies. Sealing cracks and openings around windows, doors, and foundations is an important step to prevent their entry into homes. Creating a vegetation-free barrier of at least three feet around the house, using materials like mulch or gravel, can also deter them from reaching the foundation.
Once indoors, vacuuming is an effective method for removing clover mites without crushing them and causing stains. Use a wet cloth to dab them up or a vacuum with a crevice attachment, disposing of the vacuum bag immediately afterward. For severe infestations or recurring problems, consulting with a professional pest control service can provide more comprehensive solutions, including targeted insecticide applications around the home’s exterior.
