When moving potted plants into the house from outdoors, there’s no need to use chemical insecticides to prevent insects and other creepy crawlers from getting a free ride. Use this trick instead: Fill a large bucket with water and submerge the potted plant for about 15 minutes. This will give the plant a good drink and force whatever insects may be living in the leaves or pot to rise up. Allow the plant to dry out, and you can bring it indoors safely. Just don’t submerge arid-loving plants like cactuses and succulents; you’ll have to carefully inspect those leaves and remove insects by hand.
