The tiny clover mite feeds on clover and grasses, as the name suggests. The minute invaders sometimes enter homes, although they pose no threat at all to pets, people or other animals. Mostly considered a nuisance because of the rust-coloured stain they leave when crushed, these mites can infest in large numbers during spring and summer. Controlling them is often best done without the use of chemicals -- changing your landscape around, altering your landscaping habits and physically removing the mites are ideal methods for preventing and destroying these mites.
Move any grasses at least 3 feet away from the foundation of your home or building, particularly on the sides of the building that have the most direct sunlight.
Seal and caulk any openings on the exterior of the building, particularly cracks in and around windows. The mites will use these cracks as entrances to infest your home.
Sprinkle talc-based powder or diatomaceous earth around the windows or other entrance points to prevent the mites from coming inside.
Sweep up mite populations indoors with the crevice tool of your vacuum cleaner.
Supplement the areas the mites are attacking with more water. Clover mites prefer dry, sunny locations and patches to feed on, so adding more water to the area can send them on their way. Areas of damage are almost always near vertical structures such as buildings or trees -- the mites climb out of the grass to shed their skin and lay their eggs.
Mix 2 tbsp of dishwashing soap with 1 gallon water to make a spray for the outside of your buildings. Directly spray any spider mites crawling up the sides of your building with this mixture to kill them before they lay eggs or enter.
Spray or apply insecticides labelled for clover mites in areas where they develop. Bifenthrin, lambda-cyhalothrin and dicofol may all provide relief from the tiny arachnids.
Plant zinnia, marigolds, salvia, mums, juniper, arbor vitae and yews around your property. These plants are unattractive to clover mites and may help deter them from choosing your property.
