The spider mite is an arachnid that is commonly found feasting on houseplants. Spider mites are so tiny they are difficult to observe, but they are usually brown, green, red or yellow. You can determine if your houseplant is infected with spider mites by the appearance of the houseplant's leaves; spider mites leave plants with numerous tiny, light flecks, making the leaves appear speckled. If you have mites on your houseplant, you will need to kill them before they do any more damage.
Use gardening scissors to remove infected leaves. Once your plant become healthy again, it will grow new leaves.
Wet a cloth and use it to wipe down any leaves that remain on your houseplant. This will wipe away some of the mites, as well as any dust that may have collected on the plant. Dust can attract mites.
Spray the plant with a 2 percent horticultural oil insect spray. The University of Colorado recommends this spray as the most effective treatment method for indoor plants. Horticultural oil is safe to use around pets and humans, which makes it ideal to use indoors.
Repeat treatment in seven days to make sure you got all of the spider mites.
