How to Stop Spider Mites on Outdoor Plants


If you've ever had a problem with spider mites, you know the telltale signs of their existence. You see cotton webs woven around the leaves of your plants, and the leaves begin to turn yellow and then brown. Usually, spider mites are a common problem for indoor plants, but they can become outdoor pests as well. They are most common in locations that have lower outdoor humidity. With a few rare practices, you can eradicate spider mites on your outdoor plants.

Step 1

Isolate the affected plants, if possible, and spray them with water. Hose off all the leaves and stems. Make sure you also spray the undersides of the leaves.

Step 2

Introduce natural spider mite predators to the affected plants. Ladybugs and predatory mites feed off spider mites, and they can be purchased online or at local nurseries.

Step 3

Spray the affected plants with neem oil or insecticidal oil. These substances cling to the plant and will drown the mites.

Step 4

Provide shade to plants during the late hot afternoon sun. This can be accomplished by moving the plants to a shady location or erecting shade cloth to block the sunlight. Doing this helps the plant maintain moisture easier and ward off the spider mites.

Tips and Warnings

  • Failure to stop spider mites may result in plant death. Once a plant shows signs of spider mite infestation, its health can deteriorate quickly.
