The next day, wash the plant with fresh water, and repeat the process until you no longer see evidence of spider mites. It may take four or five treatments to eradicate these pests. Always begin with the least toxic method of insect control. If it doesn't work, you can take stronger measures. If you notice the presence of insects but they don't appear to have caused a major infestation, try washing plants with warm soapy water.
Gardeners often move tender plants outdoors for the summer and then back inside during winter.
When moving plants back inside for the winter, reverse the process. First take them to a protected outdoor area, then inside but away from heater vents and drafts. Wash the pots to remove insect pests and dirt before bringing plants back inside. Always check the soil on container plants before you water. The soil should be dry to the depth of the first knuckle on your index finger before you add more water.
