Wash Bugs Off Plants

Remove as many insects as possible with a strong stream of water. In the case of clinging scale insects, you might have to use a soapy cloth or toothbrush to wipe the plant clean. If the plant is small enough, it is even more effective to submerge the foliage in water. Fill a bucket or sink with lukewarm water. Then place a rag, or a piece of paper over the top of the pot to hold the soil in place. Next, with your fingers spread around the plant's stem, turn the plant upside down, and swish the leaves in water for two or three minutes.
