How to Get Rid of Spider Mites Indoors
- 1). Separate all plants that have spider mite damage from the ones that don't, keeping the damaged plants in one cluster far away from the others; moving them to another room works best. This prevents the mites from getting to the other plants.
- 2). Place the infested potted plants in platters filled with water, or hang them directly over such platters to maintain a high level of humidity. Place and run a humidifier near the plants if you have one.
- 3). Spray the plants with a mist of cold water from a spray bottle two to three times each day to help keep the plants moist and the mites away.
- 4). Mix the water with equal parts isopropyl (rubbing) alcohol and spray it on the plants at least once a day while continuing the regular water spray described in Step 3. The alcohol kills the mites on contact and shouldn't damage the plants because it evaporates quickly.
- 5). Get a supply of predatory mites from a horticulture retailer and place them on the plants if the problem persists. These mites are carnivores; they will eat the spider mites and not the plants themselves.
- 6). Use a miticide chemical to the plants if nothing else works, applying it once every five days. This method is safer for indoor plants than outdoor ones; your indoor plants likely aren't garden vegetables whose taste and nutrients can be affected by the chemicals.
