Clover mites are tiny insects, about the size of the head of a pin. They are usually bright red. Clover mites can infest a variety of plants in your garden and can even make their way into your home. While clover mites are not a danger to humans or to pets, they can invade a home in such large numbers that they become a major problem, and if they are squashed they leave a bright red stain on carpets, walls, drapes and furniture. They invade homes primarily in the heat of summer or in the fall as their plant hosts are dying back. Clover mites can kill a wide variety of garden plants. Killing these tiny insects can take patience.
Vacuum up clover mites that have invaded your home. Vacuum into cracks and around doors and windows, as well as vacuuming up any major infestations covering walls, floors, drapes or other visible areas. Check any damp areas under sinks or in areas where water pipes may "sweat" and vacuum clover mites from those areas, too.
Remove the bag from your vacuum cleaner and place it inside a large zipper bag. Close the zipper bag and place it, with the vacuum cleaner bag, into the trash. Remember that adult clover mites only live for approximately 48 hours once they enter your home.
Remove all vegetation from around the base of your home for a distance of approximately 24 inches to slow the spread of clover mites from the outside into your home.
Spread a 24-inch-wide swath of granular pesticide (consult with your local nursery or home center for the best granule pesticide for your area) around your home. Use a hand spreader to spread the granules and then water the area to activate the poison.
Kill clover mites in your entire yard and garden if desired by spreading the pesticide granules over your entire yard. Water after spreading to activate the poison in the granules.
Spray a liquid pesticide in place of the granular pesticide if it is more convenient to use a liquid. Use a lawn sprayer and mix your pesticide according to the manufacturer's specifications. Spray a 24-inch-wide barrier around your home, spraying into cracks in the foundation as well. Spray your entire lawn or garden to control a major infestation.
