Beautiful flowers may not be the only thing growing in your soil—it may also be the home to soil mites. If you've noticed small, white dots walking across the top of your soil or along the edges of your plant's pot, there's a good chance these mites have set up shop in your soil. According to the University of Illinois Extension, mites can range in size. Some mites are about the size of pinpoints, while others can reach up to 1/8-inch in diameter. Fortunately, mites are typically just nuisances and do not bother the plant; however, there are a few ways in which to remove the mites and allow your plants to be the only tenants in the soil.
Clean and filter the soil. According to the University of Illinois Extension, mites feed off of leaf mold, decaying plant material and peat moss. Therefore, removing any debris in the soil will give the mites less to live on, which may lead to their elimination.
Re-pot your plant into sterile soil. Moreover, make sure your pot is clean and void of any soil or debris.
Soak the plant's roots to remove the old soil before placing it inside the new soils and pot. While it is important to remove as much of the old dirt as possible, you must re-pot the plant quickly before its roots dry out or the plant could die.
Apply insecticides that contain pyrethrins to the soil. Note any dilution instructions and follow the directions on the label.
